Once per turn: You can target 1 "Scareclaw" monster or "Visas Starfrost" you control; it can attack while in face-up Defense Position this turn. If it does, apply its ATK or DEF (whichever is higher) for damage calculation. When your opponent activates a card or effect, while you control a "Scareclaw" monster in the Extra Monster Zone: You can send this face-up card to the GY; negate that effect. You can only use this effect of "Scareclaw Sclash" once per turn.
