Branded Befallen (PHHY-EN073) - Photon Hypernova 1st Edition

Once per turn, when your opponent activates a card or effect that targets 1 "Bystial" monster you control (and no other cards), or when your opponent activates a card or effect in response to the activation of your "Bystial" monster effect: You can target 1 LIGHT or DARK monster in either GY; banish it, and if you do, negate that activated effect.
