the strategy here is to combo Eternal Soul with Dark Magician The Dragon Knight since both are going to protect each other from being affected by other cards effect, and using Dark Magical Circle ( if you are lucky enough) for card removal but since Eternal Soul is going to protect your Dark Magician monsters you want to focus on clearing your opponent's monsters instead of spell/trap cards so you can direct attack him quickly.
this deck was tested against most of YuGiOh Legacy of the Duelist Link Evolution challenging campaigns!!!
use Left Arm Offering to search for the eye of timaeus and Magician's Rod,Dark Magical Circle and Soul Servant to search for the rest of your combo cards to win the duel.
