The Meta Magnates vs??
What team, can take down the quad of Magneto, Majestic, Hank Henshaw and Metron?
The Meta Magnates always have a days prep prebattle.
No above top tiers please.
Whatever team you choose, gets 4 hours prep, but no getting artifacts from other beings.
Doesn't have to be an official team from canon. Just limit it to 4 members.
