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.
Static ability — always active, can't be responded toRules Note
This card has a static ability that applies continuously as long as it's on the battlefield. There's no trigger or activation — the effect just exists. Removing the permanent is the only way to stop it.
