Dark Sign

Enchant Creature
If enchanted creature is sent to your graveyard
return it to the battlefield tapped and with a -1/-1 counter on it then return Dark Sign from your graveyard to the battlefield attached to that
creature (counters added by Dark Sign are not
removed when the creature returns)
If enchanted creature would be destroyed due to
-1/-1 counters it does not return, instead create a
2/2 black zombie creature token
