蕾雅卡

在世界闇處活躍的稀有卡(舊譯蕾雅卡)竊盜集團，馬利克·伊修達爾是其首領。用武力強奪，非法量產稀有卡；獲得非法的大量利益，名字由來是伊斯蘭傳說的食屍鬼。北美版因宗教緣故，僅統稱為稀有卡獵人。

杜馬首領，也是足以操縱大國政治的巨大公司─帕拉迪晤斯的首腦，其真實身分是一萬年前的亞特蘭提斯的國王。使用奧雷卡爾克斯牌組。
由於亞特蘭提斯因奧雷卡爾克斯的緣故而腐敗，因此將其毀滅並決定使奧雷卡爾克斯之神復活讓歷史重來；雖被傳說之龍與父親艾恩哈特、女兒克莉絲的阻撓下以失敗告終，但是卻在暗處不斷的操縱歷史，也親眼看見闇遊戲的過去。而且知道讓奧雷卡爾克斯之神復活必須要打開禁忌之門以及被選中的決鬥者的靈魂做為祭品的方法，因此奪走神之卡打開禁忌之門，還派遣杜馬三槍手對付遊戲一行人藉此奪走他們的靈魂，[6]。敗給闇遊戲一行人後逃往亞特蘭提斯將自身作為祭品使奧雷卡爾克斯之神復活；被三幻神毀滅後變成地球之闇現身，在闇遊戲將地球之闇封印於起來後，終於便回原本善良的模樣並在父親艾恩哈特與女兒克莉絲前來迎接下就此安息。
