For people who like CCG and roguelike, I can highly recommend Slay The Spire  as it combines the two in an easy to learn, difficult to master game. Its been developed and tested by Android: Netrunner players (CCG-wise I only ever played the orig. Netrunner and MtG in the 90s, orig. SWCCG, and recently Hearthstone). The game is what I wish Hearthstone would've been, and I haven't had so much fun for 16 EUR (compare to Hearthstone...). Its available early access on Steam. Third character isn't yet available.
I ended up giving up on it quickly when I got to the first dungeon/castle and couldn't figure out how to move through the diagonal passages. In later years I unlocked the secrets of the numpad.
