Im a f2p ninja with a bit more luck and dedication to grinding than your average player.

This is my lineup:

X-X-X

Konan-Hokage Minato-X

Wind Main-Gaara -X

My talents are:

3-2-4-3-1, using serpent as summon (knockdown to high float x2)

Essencially konan is a miniature minato. Last night in GNW I showed up with this particular lineup and managed to help beat up people to whom our group strategist said, and I quote, "we are dead". Gaara, in the mean time, is super tanky and in case minato gets nuked too early, he happens to be my Plan B guy and causes hell of a lot of damage. Also good for nullifying enemy barriers. Yes, water teams are still a problem but I am working on increasing my ini, which has always been a bit on the low side. Occasionally i switch gaara either for Iruka or Kushina, who works surprisingly well with this lineup, since her clones give extra tankiness and she also has a decent (and super hilarious to boot) ult.

As for the whole masked man question, I am currently gathering fragments for him, planning on using him instead of Gaara. I think it will be a cool lineup.
