That's what cards are supposed to do: change mechanics all the time.
that's right (that happen every time a new expansion for a game is released.. causing many decks to a complete rebuild)
but it works better on a card game not structured on pc or console
because.. it's simply more free
a program have rules that can be modified by countless rows of code
now.. it's wrong to say that is not possible.. but it can be too hard doing it or it can took too much time..
but if you can write an operative sistem.. well.. i guess you can even do something like implement a mechanic that give you the possibility to hit a pillar eh..
but.. it must be seen if this is achievable without change and rebuild the entire game..
so.. i can't answer if it's possible or not, and maybe neither can you..
