Vanishing

Vanishing is a Planar Chaos keyword ability that represents three abilities.

"Vanishing N" means "This permanent comes into play with N time counters on it" and "At the beginning of your upkeep, remove a time counter from this permanent." and "When the last time counter is removed from this permanent, sacrifice it."

Vanishing without a number means "Vanishing 0". Multiple instances of vanishing trigger separately, but they work with the same counters.

The sacrifice ability triggers when the last time counter is removed in any way.

Vanishing works in a way similar to Fading, except that they work with different types of counters and that "Vanishing 2" means "Fading 1".
