One of the finest blockchain-based cards in the game is Splinterlands. If you're a magical and strategic enthusiast, you have that one. You may buy/sell cards from the market here, or you may open booster packs if you want to play games.
The game has multiple 3rd party card markets, they are game dealers and give various forms of kickbacks. It's easy to learn and anyone can play this game.
The fundamentals of the game are at first easy to learn but soon you'll see that the game is extremely deep. Because there are almost unlimited cards, mana, and rules, always something new may be tried that leads to a game that is both rather easy to pick up first, but also leads to high depth for longer-term players that I absolutely see.
Splinterlands' overall pricing is a superb, engrossing game. You absolutely should verify whether you are interested in crypto or card games. You won't be deceived, I can guarantee you.
