Vampiric Annihilator

Deathtouch, lifelink

This creature’s power is equal to the number
of card types among cards in all graveyards
and its toughness is equal to that number +1 .

Whenever this creature deals combat damage
to a player, you may mill that many cards.
If you do, you may put a creature card
from among them into your hand.
