u/Low-Sherbert-8176

I'm returning to the game after an extended break and just want to raise my umas to be nice and strong. My only problem is I have no idea what cards are good, or what I should be considering when building a deck around certain characters.

Is there any chance I could get some help? Or at least be pointed in the right direction? My main focus would just be completing URA careers to learn more about each uma, and building a good TT team for a steady allowance of carats.

For reference, here's all the cards and umas I own. All cards are uncapped as much as they can be.
