Gravespawn

Descend (If you have ten or more permanent cards
in your graveyard, you get the crypt's blessing for the
rest of the game.)
Gravespawn gets +2/+2 and has haste for as
long as you have the crypt's blessing.
"A strong pair of legs may carry you far, but with necromancy and a few brutes can take you to the edge
of the world."
—Ana Iora
