I think and underlying theme among teams costumes would be nice.

Iron Fist, because I love his comic, and it's doing well, and I think it's only gonna get better as it keeps going. And because if he doesn't have a good year, I may just switch publishers. lol

The next three cause they'll be with IF.

Luke Cage for the last reason, and cause he's been doing well for a couple years now, why can't his streak continue?
