Current Shaddolls can go a lot of ways. Tearlaments are probably the best option right now with them. They mill the Shaddolls and can also fuse with them to summon stuff like Winda. Shaddolls are usually a smaller engine in this deck, but you can use more of them and the in-archetype ways to fuse to go Shaddoll centric. People usually don't do it because the Tearla and the generic fusions are a bit stronger
