Place: the chessboard
Reed Richards vs. Tony Stark Winner plays winner of... Bruce Banner vs. Beast
Bruce Wayne vs. Lex Luthor Winner plays winner of... Ray Palmer vs. Cyborg
Rules: Each match-up is a best out of 3. The game is chess. If you can't tell from above, the winner of the Richards/Stark match-up plays the winner of the other match-up in their division. Similar setup for DC. Ultimately, a winner will emerge from the Marvel Division to play the winner of the DC Division.
You can tell me who wins round-by-round, or you can just tell me who you think will take home the chess championship! GO!
