Idea is same as usual; fill and refill until you can close you the game with savage roar. Goru the Mightree and Greybough is if you go late (you'll only wanna get this late in the game against aggro) and they're to give your treants better ability to trade and to defend your token board respectively.

I may add Poison Seeds as an answer to taunt boards (although that sounds like an already unwinnable board state tbh) and might add Voracious Reader if I'm out of fuel too many games in a row.
