The deck features 3 copies of Yorvo, Lord of Garenbrig, which is already a very strong creature at 4/4 for 3 mana, but also gets stronger each time you cast a green creature (and all your creatures are green!) The deck adds 3 copies of Thunderous snapper, which is already a 4/4 for 4 mana, but also draws you cards each time you cast big creatures
Wheel of Fortune has the advantage of filling your graveyard and enabling discard payoffs, while Timetwister nerfs graveyards
This also means there isnt much reason to put our commander into the graveyard should it die, since we dont get its cast trigger if we cheat it into play by some other method
Hydroid Krasis is probably the biggest offender out of all of those
The people expecting Xenagos to stay at $40 were betting on a two-color planeswalker being so good that it would see play as a four-of in multiple tier 1 decks, which never seemed likely to me
I also apologize if I missed anything you like, but Im sure youll let me know in the comments
