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.)

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.
