A Dark Magician deck that Focuses on protecting Eternal soul with Dark Magician the Dragon Knight, which is also protected by eternal soul. This is a difficult board to out, but it is still possible by tributing or battling the dragon knight or non-destruction, non-targeting removal of eternal soul, such as evenly matched. Also included the DPE engine and Red-eyes Dark Dragoon, which can be made by eye of timius or secrets of dark magic. Can also make Baronne de Fleur with DM and ash.
The side deck is just other possible inclusions to the main deck rather than an actual side deck. There are a few cards that could be replaced with better cards, like Magician of Dark Illiusion and Magikuriboh, but I don't know what would be better in their place.
