Main flaw, p1 haku haha.

What is your purpose? Manual barrier ninjas in first position are typically only used vs PvE (unless you know and want to hard counter an opponents lineup). The moment you fail to get barrier off in R1, you lose the ability to skill in r2, and haku is your only ninja that has a chase trigger.

R1, you start off with 20 chakra, if you dont cast haku, he does his standard attack, so you have no chance of casting barrier. If you do, its an easy interrupt/acu. Max chakra you can get in r1 also is 60 IF both Ao clones die, and you have 100 chakra worth of skills you c*e in r1.

What you want is to have a lineup with at least 2 chase triggers, and a reliable one for p1 in r2 (like main shark bomb or skewer). 1 mystery chase trigger is doable if you have a better synergy and damage coming from the others, but not from this lineup.

Haku is ok, you just need to maximize his chances of getting barrier off.

1 option is to use Kisame. Unless the enemy has a way of generating chakra (like Sage naruto), Kisame forces the enemy to skill before getting hit and have 20 chakra stolen. With both Kisame and Ao, you can either acu the interrupter/acu in the opposing team, or just drain his chakra, then only trigger haku barrier. This would ensure you the highest chance of entering R2 with haku barrier advantage.
1 drawback of a p1 kisame is quite a number of lineups use kimimaru to tank 2 rows, which in case kisame would fail to connect on his standard attack and drain chakra, so you either have to use Ao to counter the interrupter, then barrier, or line Kisame on the bottommost row (Kimi will be in mid row almost all the time to tank 2 lines)
