The issue seems to happen if you go into the Deck Builder more than once. There is an overlay that keeps happening with the deck image and card image that lays on top of itself and is preventing the dragging and dropping of a card onto the area that allows it to change. I've uploaded a video and my user log to assist with this.
In this video I opened and closed the deck builder about 2 dozen times to exaggerate the issue, but as you see my mouse highlight over the deck area it moves are each overlay is hovered over until they finally all move over.
The only way to be able to change your deck image after this happens is to exit the game completely and load it back up. Then you can change only one deck image and have to rinse and repeat the above steps to change another one.
