Unless they're adding locations and limiting the game to 6 turns (usually), I'm not really interested.
I'm sure there's a lot of people out there excited for Marvel stuff in MTG. Good for them I guess. Personally, I'm more interested in WOTC focusing on creating new, interesting stories and planes, but that ship sailed a long time ago sadly. I guess eventually the in-game universe will collect dust next to battles, world enchantments, fortifications, and a low power standard format.
