Lord Malzebeth

When Malzebeth enters the battlefield choose
Artifacts, Creatures, or Enchantments.
Whenever Malzebeth attacks, mill cards equal
to his power. Once per turn, whenever a
permanent of the chosen type enters your graveyard this way, put a +1/+1 counter on Malzebeth.
At the beginning of your end step, return a
permanent of the chosen type with mana value
less than Malzebeth's power to the battlefield
under your control.
