Phthisis [Time Spiral Remastered]

Destroy target creature. Its controller loses life equal to its power plus its toughness.
Suspend 5 — {1}{B} (Rather than cast this card from your hand, you may pay {1}{B} and exile it with five 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.)
