team 2 wins.
Kisame is obviously weaker than itachi.
Itachi already defeated Deidara in 1 second before as well.
Deidara was almost blitz by hebi sasuke even though sasuke did not want to kill him. He also was blitzed by Sai, so
Minato who's the fastest character in the manga shouldn't have a problem with that.
Gaara won't be good either with Kisame, because if Kisame used his jutsus, that will make Gaara's sand useless, not
to mention there is a HUGE gap between his level and Minato's level. Same can be said about Kisame.
So, yeah team 2 win this with ease IMO. Zzz
