Board Game Arena

I play almost exclusively on my phone and the following situation has happened more than once:

I select a card to buy.
I select the big red confirm button.
I find that I have accidentally rested instead because I misclicked when selecting the card then mistook the big red rest button for the confirm button.

It's such a fast game, I don't really want to have to be encouraged to play slower and more deliberately. If also prefer to stay zoomed out so I can see the whole board.

Is there anyway that the UX could be improved to help me? Rest is just another option - perhaps no need for it to be the important red colour?

I think this happened to me once too.
Maybe program it so that an inquiry shows up if you already selected a card?

You can see a bit more if you select the hamburger menu on the right and choose to show gamelog in an extra column. That helped me tracking a few more things, but there should be more information overall and a better overview, I agree.
