Slay the Spire
Technically. It's a roguelike, so it's not really winnable in that regard and I'm likely to have a true ending SOMEWHERE but it's a cool simplistic card battle that runs up the mental math sometimes.

I will say I hate certain "gotcha" things like a power card that exhausts itself and drains your damage below baseline after a few turns of boosted, making drawn out encounters impossible if you fucked it up with no chance of escape (what killed my last Watcher round, actually. Thanks, Bias.) Or the malleable monster that shifted to Thorns in the middle of a multi attack. Or the hex/daze stacks when im playing a skill heavy deck. Blegh.
