I have the feeling that the new buttons are sorted inconsistently. Sometimes the right button is the one that is used most often (e.g. Spice Merchant, +action/+cards) and sometimes it is the one that is seldomly used (e.g. Minion +2). I would like the right button to be the one used most often. I know that is not a clear distinction, but I too often have to stop and read the text.
Or maybe the right most button be the one that continues in the deck and draws more cards (Minion attack).
E.g. Pageant, the right button is "no thanks". That is so counterintuitive to me
Or Scheme, where to topmost option is "Undo"
btw I really like the new interface. I find it just not consistent yet
