If you want to scratch a similar itch, and have not already, try Guild Wars 2.
It does have microtransactions, but only because they have no subscription fee and they are mostly cosmetic with a few rare exceptions.
It also has no FOMO except cosmetics from certain festivals, which you can also buy in the next year.
It is still the best MMO on the market IMHO, because it values your time and money compared to other games in the genre.
As an alternative that does not require booster packs or such nonsense i can highly recommend Compile and the Vale of eternity. Both very good cardgames that capture different feelings of playing a deckbuilder.
Never cared for CCGs since they are by definition pay to win.
