Exanimate, Navarc Undead

First strike
Whenever Exanimate, Navarc Undead attacks
you may create an X/X blue and black Spirit
Shark creature token named Spirits of Exanimate
with Trample and Myriad that's tapped and
attacking, where X is equal to the amount of
pirates you control plus the amount of pirates in
your graveyard. Exile the token at the end of
combat.
