The deck focusses heavily on getting El Shaddoll Construct or Michael the Archlightsworn out early on in the game using Lumina, Lightsworn Summoner to get a lv4 tuner (Felis or Raiden) to synchro Michael out, Shaddoll Fusion to get out Construct using whatever's available and if sending cards from the deck, I suggest Shaddoll Beast to get an additional card in hand, Dragon if your opponent has an annoying spell/trap blocking you, or Falco if you already have a bunch of shaddolls in the grave for whatever reason. Super Polymerization works to take out opponent monsters that can't be gotten around, while activating grave effects. Minerva is useful at getting more cards in either the grave or hand, Curious is good for sending specific cards to the grave, and Shaddoll Construct is good for getting another fusion Shaddoll out. Judgement Dragon and Chaos Emporer Dragon - Envoy of the End are the two good beatsticks that can special summon themselves thanks to cards in the grave.
Biggest flaw is the chance of sending too many to the grave too fast, causing your own defeat, which I'm trying out different ways to avoid it.
This deck is still a work in progress, and if anyone has any tips, I'm open for suggestions
