The best teams for EG are ones that mostly surround him with buffs-(For example), Vanilla Konan most people have her and she helps him quite a bit. If you have Konan (AOG) I would highly recommend using her though. Another ninja that people run with him quite a bit if you have him is Kisame (Samehada Fusion Mode). I would suggest your also run a team that would get his 20 hit combo off too-a person that helps with that on top of Normal Konan if you have him is Hidan (DP) and king of hell as a summon helps a lot as well.

Good luck with your teams!
