Dragonmaid combo deck with dragoon you don't need dragoon but it helps just about any deck
Going first:
Most combo lines are trying to get to spheres with some back row assistance. Spheres is strong and with a solemn or tidying in the back row it adds another negate/pop
Best starting combo line is to get out spheres and Sheou for a return and negate destroy
Going second
If you can combo off enough without interruption going into borrelsword should win you most games this deck produces enough most of the time to do that
If your opponent has interaction you can always default into spheres
If your feeling like a menace to society you can play through the negates with the dragonmaid combos and then verte into dragoon
