Mizi, Swarm's Beauty

Flying
Whenever this creature deals combat damage,
put a number of Egg Counters on target creature
equal to the damage dealt.
Whenever a creature with an Egg Counter on it
dies, search the top X cards of your library where
X equals the number of Egg Counters on that creature. Put target creature from amongst those
cards onto the battlefield and the rest onto the
bottom of your library in any order.
