I do not know if Evil☆Twin Runick Spright is still a viable deck in the current meta, but it is a lot of fun!
Fun combo: Side in Jowgen the Spiritualist to the main deck. Get Mannequin Cat on the field. If your opponent has a light monster in their graveyard, summon it to their side of the field, then summon Jowgen the Spiritualist to your side of the field. Now your opponent can't special summon monsters (you can't either, but you should've already finished your combo by this point.).
