300 wasnt as bad as 299 imo

I honestly cant remember now if i used naruto or temari as position 1 ninja (whichever is more tanky due to #2 fight). It makes no difference though. Make sure to put sage naruto last, so his clone doesnt get wind buff from main by accident. Pakkun as summon mystery

1st fight: R1- temari on hashirama to prevent barrier. R2 sage + gaara. Once hiruzen dies- temari on him to interrupt via gaara's chase. Once interrupted hiruzen is left, dont use mysteries and kill him with standards so you have everything ready for 2nd fight.

2nd fight: here you start with 80/100 chakra. Wait out until enemy chases end (2 out of 4 units will be immobiled). IIrc they dont absorb your chakra there (if they do, just hope for luck and queue kazekage early- hope he dodges interrupts). Best case scenario is main is able to move- queue up main reset- once dogs pop dodges, queue up every available mystery and just burst down that team. Next round fire everything again and they should be dead.

passed at 2nd attempt once i figured out team and priority point listed above. All ninjas were alive (although top right ninja barely after 2nd fight combo). Team power was around 200-210k
