I found out about this game a few weeks ago and I have to say it's probably the most fun and refined play-to-earn crypto game out there right now. It's basically a mix between Magic: the Gathering online and Hearthsone. Players earn cards for free by winning games and leveling up. Players can also trade cards on multiple third party marketplaces. Cards are owned as erc-721 tokens on an Ethereum wallet. It's a super awesome concept and the game itself is fun too! Since it's pretty new, there's only a core set so the gameplay isn't super diverse, but they will be releasing a new set very soon I think. Try it out for yourself it's a great game!
