Undoubtedly my favourite blockchain-based game right now, already #1 in 30d amount being spent and the game is in it's infancy with only a handful of teams licensed across the globe. New players are allowed to enter a separate league where they use free common cards they receive at the start to insulate them and protect them while they adapt and get to grips with the game at the start. Already in place is the concept of levels which will force those with the most amount of money to continue to pay for new cards to compete in the lower divisions or be forced to compete in the higher divisions - this provides everyone who are winning cards in the lower divisions the ability to sell their cards to fund investments in better players. Love the fact it's on Ethereum and I can export my players to my Argent Ethereum wallet if I want to hold on to a player for a long time without using them.
