How would it handle switching from a fire-gravity to fire-gravity-earth or vice-versa.
Load a Dual-Card (it splits them back to the basics).
You add your new card in the third slot(or re-arrange and add it in second maybe).
Pay full to generate the Combined-Card, or would you only pay the difference (+ penalty). So maybe difference*1.2.
Why increase the price? Getting a deck ful of these would cost a lot, especially if you don't need one of the elements anymore and need to replace your pillars.
What do you do when you re-design your deck? Are you out all those pillars or can you just forget the cash and revert them all to basics to be swapped out?

Going fairly simply on a 1.2 multiplier for adding a card and 0.8 for removing a card, the + column would be how much it would cost to add 1 card from the current setup and the - would be the same for removing that card. The Total+ and Total- columns are the final cost of the change(not cumulative). The combined cost for multiple cards would be simple enough to calculate.
* i was bored and it was easy enough so i did the table up to 12 cards as 1 slot for each color
Then, if you choose, you could just scrap everything and fully revert the card for free (or maybe half the base cost to generate it).
Also, would it allow Quantums to be added?
