I've been using super queen too as a max TH9 bar heroes/walls, it's almost as good as before you just have to be more liberal with her cloak and rage spells. I use archers instead of minions to reduce my DE costs. In crystal at the minute but climbing.
However within 3 days I have enough DE to upgrade her again and I'm struggling to find a reliable army to farm with when queen is in the salon. Any suggestions are welcome!
Queen currently at 21 (going to 22 after war attacks), King at 20.
