This Magic card removes a monster from the field for one turn , and I ’ m using it on my own monster — Dark Assailant . So your Machine King loses 100 Attack Points since my Dark Assailant is no longer on the field to give him extra power . And it gets better — check out this Magic card . Nezbitt : Play whatever you ’ d like . There ’ s absolutely nothing that can save you now . Duke : Is that so ? Not even . . . this ? " ( shows Nezbitt the Dice Dungeon Magic card in his hand ) " Nezbitt : " ( shocked ) " A Dice Dungeon Magic card ? Duke : " ( smirking confidently ) " You don ’ t know me , but let ’ s just say I know a thing or two about dice . And now it ’ s time for me to roll you right out of this Duel — because I ’ m changing this card game to a dice game ! Serenity : There are stars all over the Monster cards ? They must look so pretty , huh , Tristan ? Shizuka : They must look like a ladybug ! How cute ! ( the Japanese version of the above line ) Featured cards .
