Yours Force of Will - You added it after our discussion about counter spells. I think I may have been going down the wrong path by thinking of counter spells, but this is arguably the best one ever printed so it might be worth keeping even if Niv can't fish for it. Wilderness Reclamation - I gave some thoughts about it above, I think it's too narrow for my tastes and I don't like that Niv can't fish for it. Angel of Despair - I needed to cut one thing from Orzhov and this seemed like the right choice over Ashen Rider because exile is more potent and it can trigger twice situationally.
Mine Astral Drift - I put in a proxy of it to test with, it definitely feels good to hit the Astral effect more consistently while also providing an enabler or one time use version of the effect. Molderhulk - I wanted to round out Golgari a bit more, and this guy provides some ramp if you've been cycling or discarding to hand size. He also ends up being a much easier to cast version of Rakdos' 6/6 body. Rhythm of the Wild - I found a unique answer to the "counter war" problem I was facing, and it also acts as a haste enabler or an anthem if you already have a haste enabler. I kept it in my opener for the turn three play and it ensured Niv hit the table, I felt really good about it.
Do you mind sharing your thoughts about the recent changes you made and if you have any on these few cards?
I will be adding Soulherder (to both decks) and of course Astral Drift once I get my hands on them.
As far as mono-colored cards, they have to do something special for the deck for sure. Seedborn Muse is normally better than Wilderness Reclamation, but the curve of Astral Slide, Wilderness Reclamation, Niv-Mizzet Reborn is what we are aiming for. Have I eve had that? No, lol. But Wilderness Reclamation has proven to be fine.
I have to say just drawing Force of Will naturally does feel pretty good. However, if you're a good player, you can find opportunities to slip a cascade under a counterspell, especially with Violent Outburst at instant speed.
I thought about New Perspectives as a mono-colored alternative, but the cost isn't really worth it. Archfiend of Ifnir is another mono-colored card that would be great.
Too be honest it's a bit too much of a can-of-worms thinking about mono-colored cards, as one of the simplicity of Niv-Mizzet Reborn is that you can concentrate on color-paired cards. If I have to think about the 15,000 odd cards I think my mind will explode
Rhythm of the Wild could definitely be a winner. Time and time again haste to all creatures has been a winning combination.
I found Swans of Bryn Argoll is often a liability as opponents have turned it around and used it for card draw by targeting it for damage. So you can't play it out. Even with the combo of Niv-Mizzet, Parun or Niv-Mizzet, the Firemind I've not used it because by that stage I've already combo'ed. Angel of Despair was fine, but I'm putting in two Orzov cards so.. Leave // Chance is the slowest of the discard lot.
Hey darrenhahib, I was reading and saw where you said you've played around 50 games with the Astral Genesis deck. Are you playing on Magic Online? Just curious what platform you're testing on
Very much interested to see how this version develops!
Yes Magic Online is where I get reps in, but I have a commander group for paper as well.
The thing with online is that people don't know what you're playing fully, so the Living End and Hypergenesis is totally unexpected and not planned for by opponents, so in this respect it's not a true indication of play testing, but I don't play these sorts of decks for any serious competitiveness.
What about Reflecting Pool? So many dual colored lands it should work. Doesn't cost life to tap.
I've never invested in a Reflecting Pool, as it doesn't fix a color that you might be missing in certain situations. I've always been a fetch-land into duel lands, with the 5-color lands that deal damage almost having no downside in 40 life commander. I guess sometimes it's just a preference thing.
How do you consistently get Astral Slide in to play? I was using tutors in the first draft of my deck, but you only seem to have a couple of cards that are able to get Astral Slide for you.
Hey SirGregarious. Well I've been playing the Astral-Living-Genesis deck a lot, and the thing is that I hardly ever play Astral Slide unfortunately due to...well hardly ever drawing it.
But that's OK, it turns out you only need to get a single to a few activation of Niv-Mizzet Reborn to probably set yourself up. If you can get more then great.
I should really change the thread explanation, and have the idea of the Astral Slide as kind of a bonus, rather than the name sake of the deck. But I would have never gotten the core idea of the cascade plan without it, so just left the thread as the original theory-crafting explanation.
I've probably played like 50 games and had a proper Astral Slide setup twice. But I still win a lot of games, because the Living End or Hypergenesis just end up being too much for opponents, with just a single/few Niv-Mizzet Reborn triggers.
With all that said however, the cyclers are fantastic, especially the land cyclers. You get land drops off Niv-Mizzet which is great. But what I've been doing is removing the non-land cyclers (because Astral Slide isn't a huge factor to the reality of most games).
I should add a section "How to play" now that I've got a lot of experience under my belt. That'll be my next task for this thread, and it'll explain things more clearly.
Rasputin Dreamweaver - I'm not even really sure how this card helps the game plan. It's a seven CMC card that makes one colorless mana every turn after sort of paying for itself if you hard cast it. If you're getting it off of Hypergenesis or Living End, you're probably already about to win the game. Azorius has the most cards in your list, and I think he's one of the least helpful cards in the deck overall.
I've had good interactions with Rasputin Dreamweaver. It's not always that your Living End of Hypergensis is a massive one if you're going for it early. Setting up for further things does happen. He is not a key card however and it's a $124, and Azorius is on 7 color-pairings (highest), so this is easily replaced if you want.
Actually as it turns out Rakdos, Lord of Riots has been the least useful of the creatures. Never cast it on Turn 4 (of course) and the colorless portion can only be used on creatures. Where I've used Rasputin Dreamweaver for things like Eldrazi Displacer activation's.
Then Golgari Findbroker has also been something I just never used. Really need fetch land to get any use, as I don't want to put creatures back into my hand just in case of Living...stuff.
Underrealm Lich - This card isn't in your deck, but I imagine it lets you filter your deck and pitch more stuff into the graveyard, as well as fixes your hand way really well. Golgari also has the least cards in the deck, do you think it would be worth it to include it?
Too be honest I misread Underrealm Lich and thought it only grabbed creature cards for some reason. It's definitely a powerful slot for Golgari and worth a try with adding The Gitrog Monster to the mix already.
Yeah I guess because it doesn't have an ability that is very relevant to commander, that I didn't end up adding it, although haste to all creatures is suuuuper great if you have it. Just killing off the person that could deal with your board means that you normally win the game in that situation.
I have to say much like Astral Slide, I have cast Immortal Servitude only a couple of times. Casting it for 9 mana to get the 6 drops has only happened when I had Cadaverous Bloom to fuel the mana to cast it.
So in the end, distributing your casting costs, doesn't really matter long term for the deck.
In general, I felt I would be happier with some more counter spells to protect the combo pieces better. Counterflux, Ionize, Render Silent, Absorb, Psychic Strike, Undermine, Voidslime are all 3CMC counters that don't interfere with your Cascade plan. I imagine if you ran some combination of them, it would be almost impossible to not have at least one counter spell ready each turn. Do you find that just Perplex is enough most of the time? Or do you just find yourself not in counter wars or not in need of protection very often?
I NEVER have mana spare, certainly not three in opponents turns. I was thinking about Force of Will as a non-color paired card that I might naturally draw, and I just did a count of 26 blue cards, which is fine considering Niv-Miz draw into blue cards as well. There is also Force of Negation, which could be worth considering as well.
I also noticed that you have all the shock lands except for Blood Crypt. Would it not be better to use it instead of Grand Coliseum just to avoid lands that enter tapped? Or is Grand Coliseum good enough to ignore the fact that it enters tapped?
It is nice having colorless sources for Eldrazi Displacer, which I have used.
Then the last thing I could think of is that you're a little light on Orzhov cards, having the least in the deck tied with Golgari. Are there any more Orzhov cards that you think could be worth running? Ashen Rider and Angel of Despair are the only two that come to mind for me.
Well as I was saying about hardly ever casting Immortal Servitude, that you can really switch your creatures to something that you are straight up think is a great core. This might just be better to run Ashen Rider and Angel of Despair over others.
Just a suggestion, but I think Mina and Denn, Wildborn might be worth looking into for players doing a budget list when it comes to the mana base. The ability to drop more than one land on to the battlefield is really good when running all ten of the Ravnica bounce lands. might even be worth putting in one or two more effects like it such as Rights of Flourishing, Azusa, Lost but Seeking, Wayward Swordtooth or maybe The Gitrog Monster (with perhaps a crucible of worlds style of effect) depending on the collection and budget.
I'm inclined to try Mina and Denn, Wildborn in my Astral-Living-Genesis deck, because of the land cyclers, it is possible to grab multiple lands in a turn.
There are a tons of different ways to play a 5 color land base and certainly if you were running the bounce lands then you'd certainly look to play out the additional land cards per turn.
Great deck! I've been fascinated with optimizing a Niv-Mizzet Reborn deck ever since the card was spoiled. I was disappointed by the number of non-two-color cards in the initial deck lists I saw.
Steward of Valeron is something I should play over Wildfield Borderpost for a Selesnya pick as it's probably one mana less to cast.
Yeah 9 out of 10 times I'm hard casting the borderposts. Returning a land to hand feel pretty bad if you have other lands in hand. But I am only running 35 lands, so if I'm super disciplined I can fetch for my one basic, but that is pretty hard to do when you want to be color-fixing as well.
I like the perfect 6 for each color-paring, I'm not that disciplined Had to go for a bit of quality, but I still feel conformable with the distribution (we are talking hairs of percentages).
Unbender Tine looks like a very versatile card, mana being the first port of call, but of course can untap anything. It's a shame that I already have 8 in Azorius.
I did have Draconic Disciple lined up for Gruul but I went with planeswalker options for mana generating instead. I a bit of a sucker for walkers.
Thanks again for sharing and keep us posted on how you go.
What about Underrealm Lich for the cycling? The only downside I really see is the fact that it cost 5 instead of 6. Lets you control draw better and feed the graveyard.
There is a massive payoff with Underrealm Lich. Even if you just use your one draw for the turn, and put 2 cards into graveyard, that is pretty good. Helps to even the color-pie distribution as well.
I'm going to try it over Architects of Will as Dimir has the most cards.
I really love your deck brew. I tried a few test plays and thought it was fun in a way I don't usually play. I was wondering a few months ago how to use Astral Slide in a fun way.
I might have missed it, but can you get Astral Slide with Bring to Light?
Thank you, it does attack tha game on quite a few different levels, that's for sure.
Yes you can use Bring to Light to get any card 5 mana or less, as long as you have enough different colors to pay for the amount you want. So as long as you use three different colors to pay for Bring to Light you can get Astral Slide.
Drawing Living End or Hypergenesis is a pain, and suspending them just gives the game away waaay too much. As Foretold allows you to cast them if you draw them. Also As Foretold can just be used to cast other cards eventually, so seems worth it.
I also wanted a way to cast Living End or Hypergenesis from the graveyard. Goblin Dark-Dwellers allows you to do that.
This give you alternatives further into the game.
I actually find that I will always having multiple cascade cards, so it's fine to fire one off even if you're not sure if it will be from the hand (Hypergenesis) or graveyard (Living End). You can just choose not to cast it. Then later on in the game you can potentially use Goblin Dark-Dwellers to cast it again. Also insurance against your spell getting countered as well. Further to that you might just want to cast it again later on if the board has been dealt with.
Rasputin Dreamweaver has been a nice 6 mana creature that can provide mana. I see it's a $128 these days so understand if you don't run it.
Sorry to bother, I've been doing a bit of proxied testing with the Astral-Living-Genesis list because I have Reaper King Slide and had many of the pieces. I was wondering if instead of one of the other rainbow lands in the deck if [[Grand Coliseum]] would be a good include. The deck struggles without Slide, and Displacer is a very good alternative. I just have struggled to get 2+ colorless lands consistently, and think Coliseum could help that greatly.
It might be that it's better to bite the bullet and just play a few more tutors like Demonic Tutor and Vampiric Tutor to have a few more shots at getting setup with Astral Slide. It means that these will be possible cascade targets, but let's face it, you can just get something that will allow you to do what you want anyway with these. I mean you could literally just get another cascade card and go for it again.
So I'm pretty tempted.
Heartwarming Redemption is perfect for the Astral-Living-Genesis deck, allowing you discard cards to make the mass reanimation cards work.
Also it gives Boros another card which only had 4, so now 5.
Having the spare mana to actually use the The Scarab God ability is not going to happen very often, and not a 6 drop creature either, so doesn't fit into the Immortal Servitude plan of aiming for 6
Dimir had 8 cards as well, so wanted to take from the highest color paired.
Decimate frustrates me lol. Too often no one has an enchantment so you can't even cast this card, or you have to destroy your own enchantment
Casualties of War is a new spoiler which fills a similar role but in Golgari and has the upside of not needing all the targets, however much more mana intensive. But still very powerful card.

Pretty much the recurring thing that has happened in games is that I wish I had ways to remove creatures from opponents graveyards during longer games with Astral-Living-Genesis with setting up Living End, Living Death and Pyrrhic Revival.
So I've added Ashiok, Dream Render, Kaya, Orzhov Usurper and Kaya's Guile to do this.

Other cards to look at to help with colorless are Kydele, Chosen of Kruphix, Weaver of Currents.
Another slightly strange option is that three of the cards have basic land cycling, Ancient Excavation, Grave Upheaval, Sylvan Reclamation, so you could run a Wastes.
But once you start dedicating cards to colorless in a all color deck it becomes a bit of a nonbo.
Bounty of the Luxa is a nice option as it gets colors and colorless.
It might be that it's better to bite the bullet and just play a few more tutors like Demonic Tutor and Vampiric Tutor to have a few more shots at getting setup with Astral Slide.
