Grymm, Necromancer

Flying, vigilance, haste, deathtouch
Whenever Grymm enters the battlefield or
attacks, search your library for a basic land
card and put it onto the battlefield tapped.
Whenever you cast a creature spell from your
hand, surveil X where X is its mana value.
When you do, you may return a creature card
with mana value X or less from your graveyard
to the battlefield.
