How do you actually play this game? I’m not into card games in general but this one seems oddly interesting

I unironically have a wallpaper just like that. I love taking screenshots of games I play and putting them on my desktop. Some of them tend to be rather bright, but they get covered by other windows most of the time so they aren’t really a bother.

And I still refuse to use the ‘Complete and Instant Annihilation of the Final Boss’ potion since I may need it in the future.
