Selene, Death Dealer

Deathtouch

Whenever a creature dealt damage by Selene dies
this turn, you get an experience counter.

At the beginning of your end step, if you have 5
or more experience counters look at the top four
cards of your library. You may put a Legendary
Vampire from among them onto the battlefield
tapped. Put the rest on the bottom of your
library in any order.
