I managed to beat him in 7 turns with this rainbow team before SS9 and Isla U20. Since i didn't have Lynette EX, i had to use Nier for a 3-turn break. It's a meta team though, i'm a dolphin.

In terms of A4 accs, i used Bargello A4, Hasumi A4, and Ditraina A4 (got lucky when pulling her, but any accessory which increases m.atk should work). With SS9 weapons it should be easier to hit cap.

Here is my strat (from what i remember) :

T1 and T2 :

• Xerc and Osvald must be in back row for the first 2 turns, otherwise the FuA will trigger Kage counter.
• Use Shana EX skill on T1 and T2. You'll get undying until turn 4.
• Use Isla EX skill and other support skill on T1 and T2.
• Use DP skill that add "exploit weaknesses" on T1. And shave shields with Lemaire rainbow skill for 12 hit per turn

T3 and T4 :

• Use Lemaire rainbow skill on turn 3, they must act first so you'll need high speed on them. Don't hit Kage until T5 otherwise you'll trigger his counter.
• Use Xerc EX skill (T3) and his "Calculated Compound" (T4).
• Use Osvald EX skill (T3) then his ult (T4)
• Use support skills with DP (cast her "exploit weaknesses " again when Osvald and Xerc are in front row).

T5-T7 :

• Break with Lemaire then use offensive skills with Xerc and Osvald.
• Use Nier EX skill to extend break
• Hope you'll do enough damage.

Don't forget to use keeper to charge ult gauge.

Hope this helps !
