Shai'tan, The Dark One

Indestructible
Shai'tan, The Dark One is not a creature as long
as your devotion to black is less than seven.
Eminence—Whenever a nontoken creature you
control is sacrificed, if Shai'tan, The Dark One is
in the command zone or on the battlefield you
may exile it, if you do return it to the battlefield
at the beginning of your next upkeep.
