The main problem of empress build is that there are not many viable girls in the game.

A build that could work now could be hebihime, mei, sailor sakura or common sakura full breakthrough so that can clear all the debuffs every round, but still is nowhere as good as other lineups. The main issue is that flower barrier should actually give also some kind of boost to females, something like the new pose of duel of earth main, not only removing one stack of debuff.
