I noticed that shaddolls could have their effects activated by the discard of Dark World effects, and no one has tried building a deck on here using that. If you see a way that the deck can be optimized, like better extra deck cards, please tell me. Side deck was left blank cos I am not sure what to include :P.
Shaddoll fusin seemed like a good idea to use at first, but you get more consistency if you dont play any.
