So I think there could be any number of terminal actions that work like this:
"Choose one: [Whatever the card actually does]; or +1 Card +1 Action"
Basically, this would allow for a card such as Counting House to just replace itself if you draw it at the start of a shuffle.
Obviously this would make any terminal much more powerful, as you don't have to worry as much about terminal collision (terminal collision would still stuck a little, because you then spent whatever it costs on absolutely nothing for the shuffle where you got 2 in one hand).
Current cards where sometimes you wish this existed on:
Sea Hag - not that it needs any more power! But it would be nice if it didn't become basically a dead card after Curses were gone.
Moneylender
Coppersmith
Counting House
Stables
Spice Merchant
Tactician
Of course, I realize that Pawn basically already does this. Hamlet too, to some extent.
So, what is this ability worth? Would it turn Counting House from a weak $5 into a strong $5? Or would it actually raise the cost? Does it make Stables $6, since that's already a strong $5? What other types of card text does this work well on? (Anything where sometimes using the main ability is worthless depending on the rest of the hand).
