Without prep time, Thanos kicks the shit out of team one.
Team two wins.
Current Magus had trouble taking a full blast from Dr Doom.
Warlock?
Goddess? She's getting creamed.
Warlock and Magus got knocked by Doom already. I doubt Goddess is any more durable. Thanos takes shots from Odin.
Make it a prep time fight, throw in Reed or Kang to replace Morg and it'll be an interesting fight. Heck, make it an artifact collecting prep fight and you've got something.
