Alright here's the situation:
I survive with my three players after the hell battle with Paragon and now it comes a more hell battle!
Before i can act Trema do three movements(although i have Speed Bracer to Yuna!!)and kills my three heroines!
I have Dark Night Dressphere to Paine(LV-88-9700 HP) Thief to Rikku-LV86(So i can use healings iteMs faster with the Treasure Hunt Garment Grid) and Gunner to Yuna-LV-83 so with the Cat Nip to kick ass..
But Trema execute my team before i can basically move!

Any good tips?
