If you haven't played Slay the Spire yet, I highly recommend it. Never thought I'll find myself playing a roguelike deck-builder, but this game is just a massive amount of fun. It's got a huge depth to it, and you can always keep learning and improving.

Beware though - it's highly addictive and can be a huge time sink ;-)

If you want to get started or improve your game, check out Jorbs - he's a twitch streamer and probably considered the best Slay the Spire player out there. He's got a YouTube channel[0] where he uploads "over explained" runs, in which he shares his thinking processes and the logic behind his decision making. Definitely helped me improve!
