I really would love aesthetic changes you pay for with micro-transactions. I do it all the time for big name games that offer the same (Borderlands 2, Maplestory) and the changes can be simple to complex. I know this probably won't happen, or won't happen anytime soon, but Zanz if you are reading it would be really cool. Simple graphic changes/color schemes, fancy emblem around my arena deck, alternate card art/card backs, different duel area designs, deluxe fancy graphics for creature abilities/etc. I would totally pay for all of it haha
