Detritivore (Foil)

Detritivore's power and toughness are each equal to the number of nonbasic land cards in your opponents' graveyards.

Suspend X-[Variable Colorless][3][R]. X can't be 0. (Rather than cast this card from your hand, you may pay [Variable Colorless][3][R] and exile it with X 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 time counter is removed from Detritivore while it's exiled, destroy target nonbasic land.
