Picked up the game just last week here, and also introduced it to my wife, who barely plays any video games at all, but likes card games in general. We were both immediately pretty addicted.

It doesn’t start off with nearly the level of complexity you’ll see discussed here, and you can enjoy yourself with it basically immediately. The complexity will come in as you play more and unlock more cards/push to do challenges and harder stuff once you’ve won the game many times.
