They breeze through rounds 1-3. Pein could be a problem, but with Ayon's speed and resilience, he could probably get past Pain's abilities. And round 5 might go either way. I don't know how well Itachi and Kisame would deal with the Akuma's evil aura and I have doubts as to how well tsukiyomi would work against Ayon. But similarly the yata mirror Susanoo combined with the sword of Totsuka could take them out, but would Itachi's limited stamina hold up long enough to deal with them? 5 might go with way but team 1 could clear 1-4.
