Nihilith

Fear (This creature can't be blocked except by artifact creatures and/or black creatures.)

Suspend 7-[1][B] (Rather than cast this card from your hand, you may pay [1][B] and exile it with seven time counters on it. At the beginning of your upkeep, remove a time counter. When the last is removed, cast it without paying its mana cost. It has haste.)

Whenever a card is put into an opponent's graveyard from anywhere, if Nihilith is suspended, you may remove a time counter from Nihilith.
