Showdown in the Badlands Cards List & Guide
If you want to get really reductive every game is just repetitive drivvle after a short amount of play.
It's definitely not a high skill game as ranking up is just a matter of understanding that the higher the rank the higher the try hard so you have to get more precise with your decisions.
While saying the game is rigged is a bit of a stretch, it's definitely not chess either. Probably closer to those "tap" games where you aren't really doing anything but the rewards activate dopamine.
One thing this definitely is is addictive. And battlegrounds is more laid back than the other modes.
