Its definitely a good early build, Storm+JJ is the earliest control combo you can do IIRC. Spider-Woman is also an interesting card to play that doesn't get a lot of love IMO
I was never a fan of America Chavez but I guess her main deal is not being drawn before you need? I generally chose Hulk or Odin, for raw power or Reveal effects
I think I'd be interesting to see options in Conquest that restrict players to seasons. I miss not being able to play KaZoo or old school Patriot. Also with all the new buff and nerfs, surely it could offer new gameplay for older players.
