Mained Crow and Avarice in Amaryllis is wack. The deck already has high brick potential. What you said about Vayu in game 2 is the reason I play 3 Grepher. It's the best opener hands down, and I feel like I always want to see it every game.
I mained Mole at nats in my Vayu list and it felt really good b/c it was around the time Hero beat was taking off heavy. Might be time to run it back 👀
