Stel, you and Jade launch a double Hydro Pump at Aeris. Then, Jade, I want you to use Light Screen and then for randomness hidden power o ryu unless he is still trapped then aqua ring. If Aeris is still up use sing on aeris and then light screen instead. Stel, Follow that hydro pumo up with a rock tomb to Ryu. Then finish with another dragon dance.

Jade: Hydro Pump (Aeris) ~ Light Screen/Sing (Aeris) ~ Hidden Power (Ryu)/Aqua Ring/Light Screen
Stella: Hydro Pump (Aeris) ~ Rock Tomb (Ryu) ~ Dragon Dance

Its late so hopefully that made sense,
