I'm only at collector level 193 but I'm really enjoying the on reveal destroy cards that I have (Wolverine, Carnage, Deathlok). Currently I have Moon Girl and Devil Dinosaur in the deck as well. I just can't wait to get Venom and more cards that work well with a destroy deck!
I’ve been playing a lot of Galactus (less dominant since the recent nerf) but my first love is always my Wong / White Tiger / Odin deck. Moon Girl / Devil Dinosaur is fun too!
