Heyo!
I'm currently around 21k bp as Breeze and able to solo normal consistently. Here is the most common of the teams I have used, along with the talents. It is a fairly low budget team as Kabuto is farmable and Baki seems to drop at a decent rate in Survival but is also farmable, Gaara being the only one one would need from paying, but it is still very effective. The max combo potential they have is 6, so it just sc*s by in terms of usability, but the clones make up for any lapse.
Round 1:
1.Sand field and nuke middle giant.
2.Wind blade either giant and let others finish them. Just before second one goes down activate Dead Souls, this way it goes next round after Shizune poison.
Round 2:
1: Do not do ANYTHING until after Shizune heals. This is one point where my team can slip because if Gaara combos I usually just restart, since he goes before her heal.
2: After Shizune heals use Sand Spear and Hurricane. If characters are in order you should get the full 6 hit combo off. Clones and bodies then attack for decent damage.
3: Wind blade combo to cleanup. Activate Sand field and dead souls as soon as she is airborne to ensure they go off at start of next round.
Round 3:
1: Patience...This round Karin will get 2 poisons and standards off before being able to be killed. This is the point where the BP break comes in. If you and a few dead bodies survive you are golden, if not this team may not work for you.
2: After Karin gets her turn 2 posion off activate dead souls, this will give someone to tank the standard attack. After her standard attack activate wind blade to get combo and let zombies beat her up.
3: As soon as turn 3 starts you have to activate sand spear (it may help to go to 1x speed at the end of turn 2 if 2x was on) as it allows you to go before she even gets the third poison off and finish her prior to.
Round 4:
This whole fight is easy as you just rush to nuke him down.
1: Activate sand field and leave it up for the fight to increase damage output. Use all other abilities to get damage down.
2: Leave sand up until after MC and Baki do their standards to increase their damage. If it doesn't appear he will die just yet this turn leave it up until next turn.
3: If not dead just use all abilities to finish, saving spear for last again.
