After play testing the deck (With Dark Prophecy replaced by Kuon, Ogre Ascendant) it seems that it provides far more usefulness when compared to the card it replaced. You have quite a bit of card draw already that has minimal or no downside (Smothering Abomination,Inspiring Call) so the loss of the card draw engine that is Prophecy has shown to not really affect the speed of the deck, so the speak, while the addition of Kuon has proved to be quite useful, thinning other peoples boards as early as turn 3. I really think you should replace the two, yes you lose a card draw engine, but you also lose the immense life loss, and the loss of that engine doesn't really end up affecting the deck. Also, I tried to find a similar card in the right colors that had a "may" clause, but such a card does not exist, and any replacements have downsides that make the slot they take up relatively "useless".
Yes, I know, have done that after putting a counter on all my lands, to make it a one sided Armageddon. Also, I found some replacements to Dark Prophecy Grim Haruspex - Similar to Prophecy, but sadly won't trigger for tokens Abzan Beastmaster - Without a doubt will be triggered, but only one trigger a turn. Triumph of Ferocity - Same as Beastmaster, but harder to destroy Necropotence - No explanation needed
You should make the swap with Revolt permanent. In all the games I've played where I ended up casting Living Plane I had far more than 4 mana so I could "combo" off with it, so its cost isn't an issue, and neither is that extra p/t boost, as Stax will rid them of everything.
I think you should cut Dark Prophecy as it has its ups and downs, and with all the sacrifices, it can easily become deadly for you. Though that card draw is relevant, the life loss ends up bringing you down quite substantially. I personally think that Dark Prophecy isn't as relevant as one would think, as the only way to gain life is Liliana, and she doesn't stay a creature long enough to make Prophecy worth playing. I've cast it 10 times, and each time it proved far less effective when compared to something like Inspiring Call and in some cases it proved fatal.
I think you could add Dryad Arbor in its place but before you decide to put the Arbor in, please take a look at these cards:
Demon of Death's Gate - 3 Sacrifice Triggers, the immediate life loss is almost irrelevant due to how small it is, and a very big threat.
Kuon, Ogre Ascendant - Not hard to kill 3 creatures in 1 turn, and once flipped, provides a constant "sac outlet"
But I personally think you have a great mana base currently and don't need to add Arbor or Tower.
P.S Dryad is a land creature, you can only play the Arbor or a land on the same turn, you can't play a land followed by a Dryad Arbor(Unless you use something like Green Sun's Zenith) just FYI.
And if I may add, you have a typo in the card choice explanation section, with Marionette Master "they life equal to Marionette Masters power"
Not only that but this line
"However, if the temptation is too much, I will give some great substitutes so as to not hurt (too much) the integrity of the deck." should be changed to "as to not hurt the integrity of the deck (too much)."
No, but if you target the Scion to have the -1/-1 placed on it with something like Plague Belcher you can sacrifice it in response to you targeting it.
I've been using this deck a lot recently and I've noticed that against any deck that runs Humility this deck sorta falls flat. As far as I can see only 2 cards can destroy enchantments that aren't creatures, those being Freyalise & Golgari Charm (Wave of Vitriol has no benefits in this situation, as Mazi won't trigger from it). Since your tutors are also creatures, you can only hope to draw into those 2, or get card draw like Arena or Dark Prophecy. Even with those two draw engines, an early game humility will just ruin the deck, and a late game won't be as devastating, but if your creatures with counters are removed after humility then it will almost stop the deck in its tracks. Also, same goes for Solemnity, though it doesn't remove any already existing counters, an early game one will pose a giant threat, but it's far easier to deal with than humility.
To sum up, you kinda need more non-creature enchantment removal or more ways to tutor?
I change the decklist to the non infinite non budget creatures matter build, and still went infinite. Primal Vigor + Sac Outlet that gives mana + Animation Module + Mazi means this is gonna make a giant army of 1/1 servos that become infinite/infinite beasts. Granted this combo isn't really efficient as a real infinite combo, but it got me a win so im fine with it
The creature clique fetches isn't because of his ability (Well it is, but the reason for it isn't), but it's rather fodder to remove the -1/-1 counter so the infinite sac begins. As without that, I won't have an infinite way to remove his counters unless I have a token generator that generates tokens in response to permanents going to my graveyard.
From reading the card a few times, it seems that Bitter Ordeal in a deck that can have an infinite sac engine (Puppeteer Clique + Mazirek, Kraul Death Priest + Phyrexian Altar + A creature in an opponent's graveyard) would allow you to completely empty all opponents libraries, right? As gravestorm would allow you to make infinite copies of bitter ordeal, having 100 instances targeting 1 player, 100 targeting another, and the last 100 targeting the last player (In a 4 player EDH game, 100 is generic)
I mean, I'm pretty sure that's how it would work, due to how gravestorm is worded, BUT safety first amirite?
