This thread might give you some ideas for teams (though some will require traits):
If you sign up on ashtender and use the My Collection feature you should be able to share a link that lists all your current troops that might make it easier for people to suggest teams etc.
Grab the guild guardians if you haven’t some of them are used in a lot of teams, and they don’t really need traiting. (Justice and Courage are the two prominent ones I believe)
