Ezaiba, Destiny's Form

Ezaiba enters the battlefield with 5 +1/+1
counters on it.
Whenever you cast a Legendary Creature, put a
+1/+1 counter on Ezaiba and draw a card.
Remove 2 +1/+1 counters from Ezaiba: Search
your library for a legendary creature and put
it onto the battlefield tapped, then shuffle
your library.
