If anyone is open to try a new TCG I can recommend Gods Unchained. It shares some strategy with Hearthstone and is quite easy to pick up. The main difference is that it is block-chain based meaning cards are linked to a personal crypto wallet and 100% freely tradeable/sellable/etc for any price and to whomever you like.
The game is currently in beta but is already hosting tournaments every weekend where it’s quite easy to win rare card packs (especially if you’re an experienced HS player). For every game you win in the beta you also receive tickets for a future raffle - these can be sold or of course provide a chance to win something.
The game has really grown on me in the last couple of months - I honestly think this is going to be THE future trading card game. In my opinion it has all the things a TCG needs: Fun and challenging gameplay, eSport and tournaments with very high prices, and simultaneously it gives autonomy back to players by letting them own, trade and sell cards without strings on marketplaces.
If anyone else is interested I would get in now before the beta ends and grab some of the limited edition cards - I have a feeling their value will be significant in the future.
