I have been earning money playing this game:
You don't need any depo to play.
You start with a free core pack of starter cards (NFTs) and as you progress to the next level, you unlock free packs FOR FREE,
You can keep levelling up and unpacking until you build a good deck, then you can forge cards and sell them for higher prices....
You can forge the free cards you earn and sell them for ETH
There's an actual market.
Their main token is Immutable IMX
I earn around $40 a week, apart from the cards I earn everytime I level up
