Deck Helper comment: This deck was posted before the 1.32 game update and as a result may work very differently now. Use at your own risk.

GravityWell, I have been testing a 30 card - Otydeck even before the sundial nerf but ended with a 60 card one (as can still be seen in the FG-section).
After the nerf I tried some variations and ended up with this. I replaced the Feral Bonds with Shard of Gratitude, as they are better in early game and reduce the need of Life quanta (FFQ and FD need enough of it; though you get less EMs). Gravity as a mark (in a deck without Hourglasses and Supernovas) assures that you can eat your opponents creatures or destroy his shields/weapons with your pulverizer, even if you have no pillars (because of quicksands for example).
As the deck has nothing to draw cards it needs two of every key card - expect Eternity which is mainly meant to prevent decking out. It needs a relativly high amount of Pillars, too, but I think the balance is ok now.
I use this deck against FG and AI5 - it has an almost 100 % win rate against AI5 (IIRC I only lost against immortal creatures once or twice and because of decking out once and due to Fire Storms / Plagues once or twice which can be normaly prevented by playing only 2 creatures). Concerning FG it has some problems against Scorpio and Rainbow and even Morte if he get's an early Arsenic, but I'm thinking of adding Quintessence when it's available to protect one or two Otyughs which may help. I haven't made statistics against FG yet, but it may win perhaps about 50 % (but that was mainly played with FB instead of SoG). Of course you can play the deck with FBs instead of the SoG - I would take 2 of them and a Phase Shield or third Bone Wall in that case. I don't know if it works unupgraded, but I think you really need the upgraded Otyughs.
edit: the version with sundials I'm using against FGs atm: I started statistics against FG before 1.17 and had a win rate of about 70 % (20 games) may be a bit less with the new version against some gods.
edit: As the imagehoster doesn't show the images anymore and the deck is still a great AI5-farmer and good FG-deck, I repost the deck codes (and hope I remember them correctly)
