Grishnakh

Sacrifice a creature: Surveil 1 (Look at the top
card of your library. You may put that card into your
graveyard.)
Put a fading counter and two fade counters on
Grishnakh (At the beginning of your upkeep, remove
a fade counter from it. If you can't, sacrifice it):
Return target artifact from your graveyard to
your hand. Activate this ability as a sorcery and
only if Grishnakh doesn't have a fading counter
on it.
