did this on my 3rd attempt, first two times i didnt save..
1. I picked Domon(atk and Def(plus hes my fav character ;p)) and Knight Gundam(reach is great after special and his SP is great on crowds easy take over on bases)
2. LEARN TO SAVE after a good portion of field take overs and aces killed.
3. If your going to not avoid multiple aces try getting them at the same time with a lvl 3 SP if no your screwed if they recover fast enough..
4. be ready for a fun finale against the BOSS, no spoilers just try and have lvl 3 ready from the start and slash away.
I had while doing it and didn't feel like a chore knocked it out easy so dont stress just feels really hard because most ppl aren't saving mid game just restarting..
Catch Me On Live Ill Teach Ya!
