Game needs an ‘undo move’ button.

Shoot me for saying it (I'm ready for your down votes) but with how 'not serious' the battle system is in this game, I find myself playing while doing other things and occasionally place an energy incorrectly or retreat and replace the wrong card etc... Would it really hurt to have a system that lets you reverse moves until after you've ended your turn?

Marvel Snap has it and it works perfectly.
