Lumis and Yami Yugi in “Unfinished Business”

Accepting our challenge was a huge mistake. When this double duel is over, you two will be banished to the Shadow Realm. Then we'll deliver both of your Egyptian God cards to Master Marik and he shall possess all three!

Wrong! We will prevail and you will release Mokuba and my friends!

Never! [draws] Just look at this. It's my Mask of the Accursed magic card. And once I place it on your monster, it will be rendered useless, Yugi! So try my mask on for size, Magnet Warrior! It's a perfect fit. As long as this mask stays on, your monster can't attack or defend! And that's not the only effect, Yugi. Until the mask comes off, you will lose 500 Life Points for every turn you take. You're finished!
