The below info is why it’s hard to make the cards NFTs (and tradable). As there are a LOT of cards. This is also why NFTs aren’t as popular on Solana compared to EVM. On Solana, NFT "state rent" is a one-time fee paid in SOL to make the NFT's on-chain data permanent. Every account created during minting (like metadata, mint, and token accounts) must hold enough SOL to be rent-exempt, ensuring the data isn't deleted. For standard NFTs (pNFTs), this typically costs around 0.01-0.015 SOL per mint. while compressed NFTs (cNFTs), which store data off-chain, cost much less around 0.002 SOL or less. Rent is the main factor in Solana NFT minting costs. So when someone mints a standard nft, like .01 sol goes to state rent. That is what later can be recovered if nft is burnt in sol incinerator (basically recycling state rent) On launch pads it's like .04 sol though, so actually shows up much more. Regardless of mint price you pay the state rent. Credit to @LegendaryLibr for the information.
