When going through the cards that you can discard/topdeck/trash when overpaying with doctor, it says "1 more" on the last card. It should say "no cards remaining" or something like that (accidentally discarded a gold because of this! Thankfully my opponent let me undo.)
Thanks for the report, vinay!
It looks like the number is off by one the whole time, but it's most obvious when it's the last card.
This has consfused me in the past. I'm not sure whether you can call it "one-off", because the question is simply whether the card I'm looking it counts or not for remaining cards.
A clearer formulation could be "x more (after this)" and "last card".
Figured I'd bump this one since it has been 3.5 years without a fix :)
