I used:

x AGK x

BD Kurama naruto Kisame samehada

x x x

talents: 32414, summon: gamaken, summon mystery: giant katsuyu.

worked by giving over 10k initiative to AGK (so that is able to interrupt roshi even by staying in move 2 and with the fact there are two ccs per round due to the unlinked chases) (185k power right now here).
