When Phantasmal Abomination becomes the target of a spell or ability, sacrifice it.
If Phantasmal Abomination becomes the target of a spell or ability, Phantasmal Abomination’s ability triggers and goes on the stack on top of that spell or ability. Phantasmal Abomination’s ability will resolve (causing it to be sacrificed) first. Unless the spell or ability has another target, it will then be countered when it tries to resolve for having no legal targets.
