The basic idea behind this deck is artifacts and using Sydri for primarily deathtouch/lifegain. I punch through with Sphinx of the Steel Wind or Darksteel Colossus and force my opponents to make tough choices with deathtouch and keep myself in the game with huge lifegains.

The landbase isn't huge, but I almost never have mana problems thanks to a solid array of mana rocks. The best opening hand I could hope for is three lands, three rocks, and Sphinx's Revelation. The strong mana base can be used to wipe the opponents with Debt to the Deathless.

Spot removal is also a theme of this deck. I pack strong white removals. The synergy behind Venser, the Sojourner/Deadeye Navigator/Conjuror's Closet and Ashen Rider/Spine of Ish Sah is also extremely powerful.

Liliana and both Tezzerets help keep my engine running. I also run a few draw spells and Fairy Mechanist, among others. Ichor Wellspring is a fun little draw/deathtouch blocker.

I'm experimenting with more boardwipes, since I can animate my artifacts on an empty board.

I'm currently experimenting with Staff of Domination and Tower of Fortunes.

I've had some trouble with Etherium Sculptor. While helpful early on, it sometimes seems a dead draw later. I've had troubles with Skullclamp as well, but I'm hoping with the addition of Trading Post, Urza's Factory, and Springjack Pasture, I'll be able to put it to more use.

My maybeboard are cards that I've been back and forth on putting in. Lattice would be useful for spot land destruction, but that'd be about it for me. I've never felt great about having Disk. Bident could be a replacement for Thassa herself.
