If your using his ult for dmg then bait the dodge first with a basic or Edo itachi ult(like many do, it's pretty useful for that if there immune ninja's) he does have super armor if i recall so that's alwayss a nice plus wih him don't really know how his dmg compares though as I don't have him. If you use him as a support be careful as i don't think he's tanky despite the super armor an the armor supression is nice but only against those that haveit Chaos is nice thhough shuts Kakuzu down.

No worries, in the future you c*ways do a quick forum search as far as I know Ice tends to have lineup for most of the released ninja's, but yeah as said above his ult isn't great on dmg so you'd have to buff him heavily but his standard lookss pretty good.

Could get founder Itachi as well for that.
