Phantasmal Bear — ruling 1

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