Cards, the plan is for each monster to have a deck of cards, as you train them, the cards will shift based on the way you train them. Right now we only really have the basic data, and some of the ui, no interactions yet, or animations. We really like how many card games look these days and are hopeful for something similar, but only later, for now it will be ugly and prototype like.
