Unless you use a spell card or trap card that lets you see your oponent's trap and spell cards, even face down, in which case you would detect it even if the oponent didn't play it.

Since one of your Marty Stuish powers is using spell and trap cards, I assume such a skill could be in your hand (probably literally). So you could detect the gun's deadliness even if it wasn't fired, if you use said cards.

Right?
