You can only use the 1st effect of this card’s name once per turn.
(1) 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”.
(2) While you control any “Yubel” monsters, all opponent’s monsters must attack them, if able.
(3) Your opponent takes any battle damage you would have taken from battles involving your “Yubel” monsters instead.
