Impa, Sage of Shadows

Menace
Whenever Impa, Sage of Shadows deals combat
damage to a player or planeswalkwer, you may
put a card from your graveyard on the top of
your library.
As long as your devotion to black is greater than
5, whenever a card is put into your graveyard,
create two 2/2 black Horror creature tokens with
skulk.
