vs
Ghost Ogre & Snow Rabbit
Card Text: When a monster on the field activates its effect, or when a Spell/Trap that is already face-up on the field activates its effect (Quick Effect): You can send this card from your hand or field to the GY; destroy that card on the field. You can only use this effect of “Ghost Ogre & Snow Rabbit” once per turn.
Dark Paladin
Card Text: “Dark Magician” + “Buster Blader”
Must be Fusion Summoned. When a Spell Card is activated (Quick Effect): You can discard 1 card; negate the activation, and if you do, destroy it. This card must be face-up on the field to activate and to resolve this effect. Gains 500 ATK for each Dragon monster on the field and in the GY.
The Verdict
Case 1: Player-B activates Dark Paladin‘s effect Player-A responds with Ghost Ogre: Dark Paladin is not only destroyed, but its effect is also negated since it is required to be on the field in order to resolve (Player-B is still required to discard 1 card as a cost for the effect activation).
WINNER = Ghost Ogre & Snow Rabbit
