Shredder, Shadow Master [Commander: Teenage Mutant Ninja Turtles] Foil

Whenever Shredder attacks a player, for each other opponent, create a token that's a copy of Shredder tapped and attacking that player, except it isn't legendary. Sacrifice those tokens at end of combat.

Whenever Shredder deals combat damage to a player, that player loses half their life, rounded up.
