Synergy guide for monster teams?

Is there anyway to get a little bit of help with team compositions? I'm still a noob and learning everyday as I play. Having a way to test team set-ups and equipment outside of the Arena, Ruins, and Exploration without cost would be something to possibly keep in mind?
