Since they started IMX, you pay transaction fees twice - once you deposit into L2 and once you cash out. I am not sure what the future holds, but all the genesis cards, etherbots and TOTG have been minted on layer2 network aka IMX... so trading cards is a breeze now. The market is not 100% complete and I think they are working on implementing Forge soon. This will give the game a boost and be a true P2E game. For now people have been stacking on flux and cards, so I am expecting as soon as forge opens to have a flood of core cards to the market. We will see. I think within the next year or so the player base will at least double if not triple. That's just a personal opinion. :)
