Just place Danzo in front of Ay,position 2 or 3,and he will chaos him.

hinata/neji pos1 could also easily counter ay, or any ninja with immobile since ay isnt immune

or since you are water main, you c*e the water clone to take the hit

well, i also have danzo on BT;

should i chaos Ay with that, and hope he hits another ninja in the same row as Ay?

choasing him is prob the best option

you could also use iruka suit, the no cheating will cancel ay's buffs and he wont do much damage

Danzo for chaos to control Ay and if you like water main then use Shark Bomb spam I guess if you have the talents unlocked (don't remember on which lvl you have all needed stuff) with Kabuto healing and prob Iruka suit or Sasuke just for ignite or some additional dps or nasty stuff. Depends what you like more.
