what website is that your using on that screen?

Konoha Proxy.

All those lineups look solid, though I do think the Kushina lineup will probably work the best due to his passive which goes very well with Kushina's kit. I think the 3rd one will work best, you have barrier + kushina buffs + cc and every round you will have a mystery available. I'm personally not a big fan of this Minato but his mystery can be very effective and I think with this you could win against kakuzu with ease, assuming you get his mystery off of course.

Edit: I also recommend you try using Fire Main's Sealing Jutsu, that team has many dodges or kushina which is immune, sealing can help you against so6p naruto, edo mianto etc.

Thank you very much man,the reason I wanna use him is because I am f2p and not full time player.So getting him is important since I am also struggling skill breaking kushina and also getting yagura(edo)

i really want kushina badly if i had her i whould be abole to use that fire team.

I would do Gaara and Kushina, because they buff each other and those around them.
