Oracle Text
Flying
Whenever you cast an instant or sorcery spell, you may switch this creature's power and toughness until end of turn.
Watch Out
Cast trigger fires even if counteredWatch Out
This triggers when the spell is cast, before it resolves. Even if the spell is countered, the cast trigger still resolves. Copies of spells are not cast, so they won't trigger this.
