I'm deeply in love with the card code being on the card; it helps a lot not needing to open up trainer whenever I want to modify a deck! However, I don't understand why the element avatar is at the bottom of each card? It seems out of place, the border continuity is broken and a tad unappealing. Also, clean up your corners: either stick with a sharp corner or rounded one. Great work overall! It's just the details make or break any design! (:
