D/D/D has been pretty fun so far, just for being able to screw up her effect damage with Leonidas and King d'Arc. Plus she doesn't have anything that can get over the D/D/D beaters except for Bouquet, and High King Alexander can give you the 5000+ damage bonus.
I don't have max copies of everything, but I'm basically relying on 3x Leonidas + 1x Kepler, 2x Dark Contract Gate and the skill for searching, and a Pendulum Switch to get any of the non-Leonidas Pendulum beaters onto the field. Without the skill, you probably want a 2nd Kepler and some Orthroses since they can summon themselves after effect damage too.
