During your Main Phase: You can destroy 1 DARK monster in your hand or face-up field, and if you do, add 1 «Yubel», or 1 card that mentions it, from your Deck to your hand, except «Nightmare Pain». You can only use this effect of «Nightmare Pain» once per turn. While you control a «Yubel» monster, your opponent’s monsters that can attack must attack «Yubel» monsters. Your opponent takes any battle damage you would have taken from battles involving your «Yubel» monsters.
