“Fake Trap” may only be activated in a chain to your opponent’s effect that would destroy a Trap card on the player’s side of the field.
“Fake Trap” will protect any Trap cards from destruction, regardless if it is face-up or face-down. Any face-down Trap cards must be revealed to the opponent to verify they are Trap cards.
“Fake Trap” may not be activated in a chain with “Seven Tools of the Bandit.”
