Maybe add Autochthon Wurm as Shai-hulud.

I think that the mechanic is more in line with self sacrificing copies like Delina, Wild Mage, Electroduplicate, and Molten Duplication color pie wise.

I wonder if there is any way to benefit from using stickers to turn other cards into demigod of revenge.

100% agree with wallisface. Imagine if you took Thassa's OracleGC, and made it an attack trigger. It would be way worse, worse than even lab man. On top of all that, even if you manage to give the ibex haste, your opponents can kill it before you go to combat.

With Barren Glory, how do you plan to get rid of your non-forest lands?

Another great deck! Personally, I think Wake Thrasher is a strong card even without infinite combos. It can easily grow to huge proportions with only a little bit of support, and is ridiculously huge late game as maybe a control deck finisher.

I like the concept, but I agree, the card as is is a little bit too powerful. I would make two key changes:

1. Knock haste off of that keyword soup or have it not trigger on etb. Twice in the same turn is too much.

2. Change the choice too the nicol bolas torment choice (i.e pay 3 life, sac a nonland permanent, or discard a card.)

Thanks for the upvote Balaam__
