So just posting the current build I run as CF, #1 as Earth on my server and consistently place in top 15 for 9 Tails and pretty high in Sage. Think I'm ranked 11th or 12th overall in server in terms of power.

I run Small Katsuyu with this.

However I'm also planning to have these 2 teams in a bit. Only have Kakuzu to get (hate ranked coins :( ) and sign in for GNW Neji

This uses the same moves as before and the purple deer for summon

This one uses the same moves as before but with purple bull for summon

and lastly one that i really want but will take a while to get, same moves as before but summon is Kirin

but hey, thats just me.

as well I am mostly f2p, i haven't bought the jonin medal but I have spent money on ingots mostly for Gaara, some mags (i don't have anything crazy for them, still trying to get level 4s). Most of the money went into getting Gakido pain and some mood scrolls. The rest of everything I have is from grinding and grinding away so the first setup at least (might be awhile before someone 100% f2p could get gakido) or the Kakuzu setup are perfectly achievable.
