The first thing I noticed was that cards could be bought individually, rather than in packs like in Hearthstone
Owning an NFT digital card is similar to owning a physical basketball card: both can be looked at whenever desired, traded with others, sold on a marketplace, and but the NFT can be authenticated without needing a 3rd party.
We still don't know how many Michael Jordan rookie cards there are in the world. There's an estimated 40 more in this case that was sold in 2020.
Blockchain solves this. If this digital Michael Jordan rookie card was created as a NFT, we would know the exact number that exists when it was first created.
Go try Gods Unchained and build a deck.
