Vara-Hero-Scream

It could be alright but I don't really know what to cut and it doesn't really synergize with the deck. The Flying/Berserk is really nice for Hero, but there isn't any way (other than Ripknife) to buff the crow itself so you can't use it to wombo people out of nowhere. Also the only synergy with extra spells is the Merchant and that's pretty weak. The extra spells can be really useful in their own right but I feel like Crow's stats make it hard to justify for that alone. These factors make me feel like it won't work very well in this deck, but it might be worth a shot. I just don't know how you'd fit it in.
