Grand Coliseum

Whenever a token you control enters, you may put a +1/+1 counter on each creature you control. Do this only once each turn. WUBRG: Creatures you control gain menace, trample, and lifelink until end of turn. Partner—Character select (You can have two commanders if both have this ability.)

If one or more tokens would be created under your control, those tokens plus a Mutagen token are created instead. Partner—Character select (You can have two commanders if both have this ability.)

Menace Whenever Splinter or another nontoken creature you control leaves the battlefield, create a Mutagen token. Partner—Character select (You can have two commanders if both have this ability.)

Double all damage that creatures you control with counters on them would deal. When Raphael enters, create a Mutagen token. Partner—Character select (You can have two commanders if both have this ability.)

Trample Raid (the Fridge) — At the beginning of your second main phase, if you attacked this turn, put a +1/+1 counter on target creature and create a Food token. Partner—Character select (You can have two commanders if both have this ability.)

Vigilance, menace, trample, haste Whenever one or more Mutants, Ninjas, and/or Turtles you control deal combat damage to a player, put a +1/+1 counter on each of those creatures and draw a card.

Choose up to four target creature cards in your graveyard that were put there from the battlefield this turn. Return them to the battlefield.

Squad 1W (As an additional cost to cast this spell, you may pay 1W any number of times. When this enchantment enters, create that many tokens that are copies of it.) Whenever you attack, for each opponent, create a 1/1 black Ninja creature token that's tapped and attacking that player.
