I have a lot of rares but i still use the following:

Guy X X

WB Asuma Sasuke X

Light Main

Talent 3 3 3 3 2

Summon: Chameleon (can switch to guys torotoise or King of Hell but i don't have them)

The trick:

1. Do not Auto, need to go manual and observe round number and keep eye on Chakra

2. Keep Sasuke's Barrier up, do not use 2nd Kirin's myst. The trick is toward the end of every three round, hit Sasuke's Kirin as soon as nine-tails is hitting you. Immediately during beginning of the next round (round 4), Sasuke will relaunch barrier before any of your ninjas attack. Make sure you keep enough Chakra so Sasuke's Kirin can be pressed every 3 rounds.

3. Trust me, the increased dmg to elemental attacks during that 1 extra round far outweighs the dmg from Sasuke's kirin dmg and loss of barrier.

4. My rotation looks like this: Rd 1) Sasuke barrier & light main's lightning Armor Rd 2) Guy's Kick Rd 3) Nothing but hit Sasuke's Kirin right after nine-tails attacks you. Rd 4) use whatever myst is available. Lightning Armor should be available again and use WB Asuma's myst here too.

5. Sasuke's barrier is especially important if you can survive more than 4 rounds.10 rounds of barriers is HUGE. Guy's leech also helps keep team HP up for WB Asuma's buff.

I also use the same strategy/team for Group Summons.
