Vanishing

Vanishing is a keyword that represents three abilities. "Vanishing N" means "This permanent comes into play with N time counters on it," "At the beginning of your upkeep, if this permanent has a time counter on it, remove a time counter from it," and "When the last time counter is removed from this permanent, sacrifice it." See rule 502.60, "Vanishing."
