Experimenting with Water main, Sage Naruto, Chikomatsu Chiyo, and GNW Tenten.
Water main talents 2-2-3-2-2 with Gamaken summon.

AF-Sage-x
x-x-x
Chiyo-GNW Ten-x

So far in arena testing, the back to back aoe mysteries in rd 2 have been absolutely lethal.
Really enjoying the full stack of poisons, along with paralysis, and immoble.

Every now and then she is in danger, but at least for my server, most people seem to have there combo starters either for the top or middle row.

But another formation I've tried out to make up for Tenten's placement is:
AF-GNW 1010-Sage
10Chiyo-x-x
x-x-x
Sage clone gets put in front of chiyo, and combo stays the same. Now it's just mainly Naruto for getting combo'd, but that's fine, that's why AF is there for heal and debuff removal.

so i ended up switching to fire main, and now using gnw neji with sage naruto and gnw tenten.

The amount of CC is crazy. Immobolize and Imprison one target first turn, use Neji to acupuncture another ninja not in the row of Sage Naruto (this is because Naruto will start off a combo that'll acupuncture the target in his row anyways) and Tenten will paralyze two random targets. So round 1, 3 ninja are controlled, and two are paralyzed. One is ignited, and one to two will be imprisoned.

from rd 2 onward, it's all about picking and choosing who to acupuncture and ignite next ;P
