MTG Salvation

I don't have much in the way of Sydri-centric combos for you, but there are a few helpful things in my Sydri deck you might find useful:

I'm slightly surprised Dispatch isnt in there.
Lotus Bloom is friends with Tezzeret, Trinket Mage, Sun Titan and Artificer's Intuition.
Reshape may or may not suit you, as well as Brainstorm.
I use a combo in mine you might try once you find your Lattice that uses the Unwinding Clock and Kill Switch to lock the table out.

I don't have the dexk in front of me but if I think of more I'll ammend the post.

Your list looks pretty good so I won't have much to say. However I will say that maybe ease up a little on the signets as artifact destruction would set you back quite a bit. In terms of the mana base are you getting mana screwed or just not the right color balance? The amount of cool combos in here is staggering and I can see how Unwinding CLock does work for you.

In my case, Lotus Bloom works with Sun Titan or Sharuum and a Dead-Eye Navigator for infinite mana. It was probably better off when Sharuum was commander though. Does also play well with your Salvaging Station but you'd need to be able to loop a creature's death somehow. If you felt you wanted to add either Master of Etherium or Tempered Steel you could animate your Bloom with Sydri, float the Bloom's mana, recur it with The Station and infinite mana that way.

Played the deck again last night and refreshed my memory a bit. Your wishlist may want to include:

Master Transmuter to swap out "trinkets for treasures" so to speak, enables etb effects, and offers a bit of evasion if needed. Best part is that returning the artifact to hand is part of the cost and camt be responded to with more removal.
Ensnaring Bridge has saved me and allowed me to combo away or in some cases plays with the Transmuter well. Pick up the bridge with the transmuter, attack, play the bridge after combat.
Glimmervoid is an Esper artifact deck's friend as well. I have so far never been forced to sac mine, but its not cheap. It was $15 when i got it, but I see its been reprinted in MM.
Getting to the bottom of the barrel here, but Liquimetal Coating allows Sydri to either offer Lifelink/Deathtouch to nonartifacts, or to animate your opponents' lands to death one at a time (I find this way keeps people from calling you out for LD while still being able to remove problem-lands)

Hi Bone_doc. Here are some thoughts on the manabase for Sydri. ETB Tap lands hurt us a little less than other decks as this one is fairly slow. I tend towards blue in my list because I think it offers the most to my strategies. I wonder if it would help if you went a similar route? UW with splash of black?

I'm sure a lot of this is on your radar already. I'm interested in your opinions. Do you agree with my assessments? What did I miss?

Manabase Crafter Website

Low cost fetches: Bad River and Flood Plain; Bant Panorama and Grixis Panorama; Evolving Wilds and Terramorphic Expanse. All three cycles require an untap step, unfortunately. That said, the Mirage cycle is probably better for you.

Non-Premium Duals In Order of Purchasing Priority (IMO):
Godless Shrine, Hallowed Fountain, Watery Grave. These were cheapest a number of months ago. Buy now or pay more later.
Temple of Deceit, Temple of Enlightenment, Temple of Silence. I think the scry is pretty great in slower decks. Look for each of these to drop if their standard decks fall out of vogue.
Nimbus Maze, Tainted Isle, Tainted Field. I like this cycle if your mana base leans towards islands.
Darkwater Catacombs, Skyshroud Expanse. Downside is obviously that you need a colorless mana to filter through this. However, these are excellent second lands if you are on a super tight budget.

Other Mana Fixing:
Thespian's Stage can double up any of your or cherry pick your opponent's best option. Surveyor's Scope if your meta is full of ramp. Armillary Sphere if it isn't. Mycosynth Wellspring if you tend to cast your general early and swing in or sacrifice artifacts for value. Traveler's Amulet and Wanderer's Twig if you go for Salvaging Station fairly often. Wayfarer's Bauble if you want to ramp in addition to fixing. Burnished Hart if you don't mind a little durdle or if you tend to end up with a lot of colorless early.
