You can't change the order they display once you are actually in battle, no. So for example if you have ten cards and you are in a battle, they will show up in a random order and won't all be on your screen at once because they don't fit. If you use them all and recharge so that you may use them again, they will be in another random order. As far as I know that's just how it works for now! So you have to be tactful about which cards you use together; if you do it right, you can still use the cards together for their awakenings. It's just a little tricky!
