Team ShazamvsTeam Hulk

Team Shazam Quicksilver, Spider-Man and Captain Marvel get taken out almost immediately, and then Thor and Hulk get completely stomped by the five on team 1.

Team Hulk Supes vs Quicksilver (low-mid diff)
Flash vs Thor (high diff)
WW vs Spider-Man (low diff)
MMH vs Hulk (high diff)
Shazam vs Captain Marvel (mid diff)

Supes vs Thor (high diff)
WW vs Hulk (mid-high diff- also MMH vs Hulk 50/50 imo, chose Hulk to even out)
Shazam on the side

Shazam vs Thor (high diff- Thor mainly wins from experience)
Hulk on the side

Team 2 wins- If MMH won against Hulk, then Team 1 would have one. Could go either way imo!
