Hi!

You could try the following team with Yagura :

Wind main will generate some clones, same with Kushina, which they'll buff wind main even more as well. If you want, you can run the wind main as position one instead and use the wind enchant passive. Make sure to copy with Yagura either a good support or a buffer from your opponent such as Iruka for example.

Yagura can be mostly combined with Roshi, since he is a easy trigger or his chase or add him inside a shark bomb team with water main and copy another healer or support ninja/main from the opponent.

I wouldn't really add Yagura in another except in a water main shark bomb team or inside a fire main position one team for you, only for the same purposes always, copying a supporting ninja.

You can try any main you want as position one for now, till you acquire a stronger ninja such as Minato, Naruto Six Paths, etc ninjas.
Also more about teams for the start, I did write a doc some time ago which is under the link https://goo.gl/DMdELn

I am working on one more like this, which will have a more clear guide about teams. If you got any more questions, feel free to let me know.
