yeah that would explain it lol
I'll add something that isn't the tutorial just in the case, every hand you get 2 MP, but also regain 1 MP in the second bet. Meaning you can use three skills total per hand.
Since the enemies can't use skills themselves, it isn't impossible to win if you don't use them either, although odds aren't quite in your favor. It is pretty funny, tho, it becomes kind of just bullshit, lol.
