From my video
Greedthorn, the full xenan variant.
I've been finding this (perhaps unsurprisingly) more reliable than my three or four color Mask lists, and the payoffs are quite meaningful. Azindel's Gift was a major inclusion I missed in the initial video, as the decks control game is strong but not as strong as an Aid of the Hooru brew. Gift gives a big helping hand against midrangey decks, especially Tavrod.
