Undead Crew

Whenever Undead Crew attacks, if you control
another Skeleton or Pirate, Undead Crew gets
+1/+1 until end of turn.
Undying (When this creature dies, if it had no +1/+1 counters on it, return it to the battlefield under its
owner's control with a +1/+1 counter on it.)
Risen enemies, called from death to fight once more.
