You could try out some fun lineups like super armor team (earth main, ay, rasa, gaara/kk gaara, susanoo sasuke). You c*so try multi attack teams like lightning main with lightning armor and blood thirsty, ay, killer bee samehada, mifune lineup.

im using ay with this team: lightning main ay darui asuma wb, and this week they sell hidan black flags. if they sell him with reasonable price i'll get mine and use this team: lightning main ay hidan black danzo!

Allright,

The usuall stuff then :]

If only ay was fire or water elemental would be pretty op, but sadly is lightning and this makes him close to be useless due to how mb interacts usually with other ninjas and lineups. At most, sadly, you can make fun teams with him, but forget a competitive team that considers him a part of it.
