Anubis, god of the dead

Indestructible, deathtouch
As long as you have less than Seven cards in your graveyard, you cant activate activated abilities from Anubis, god of the dead.
Whenever a creature you control dies, you may put the top card of your library into your graveyard.
{1}{w/b},{t}: you may play target spell from your graveyard until end of turn. If that card would be put into the graveyard, exile it instead.
