Looking for portrait card games

I’m a big fan of Hearthstone, MTG and card games in general. Hearthstone takes too long for my commute and I got fed up Marvel Snap around the time they changed to the collector cache system.

Football Manager has served me well for a year but I think I need a card game. Portrait would be ideal though not essential, and something that can be put down fairly promptly when I realise I’ve got to my stop. Any suggestions?
