Milu, The undestroyable

Milu, the undestroyable cannot be Destroyed. (Affects that say destroy, exile,
or remove from the game do not affect Milu.)
Milu’s power and toughness are equal
to infiniy plus the number car counters on each creature.
Whenever Milu attacks, destroy every permenant except for Milu. Whenever Milu attacks, put a car counter on each creature destroyed this way.
