I'd rather notbut I understand the feeling.
I sometimes double-click and get a second unit spawn on the wrong row. Once, I clicked mechanically and played my last card on the 2nd round when the opponent had passed and I was winning.
So, quite often, I wish there had been a confirm button.
But I think it would make the game far too slow, so I'd rather keep cursing at myself for playing like a fool/too quickly.
