I've run into this problem where a card gets bent and I've been stupidly rebuying full sets instead of just replacing the card that has been compromised. I figure the chance that the same card getting damaged is quite low, but I wanted opinions of those who have run games for years. I'm guessing 3 decks (1 in use, and 2 as card replacement decks) would be the most optimal, but I want to hear from your experience what you have done.
Also, how does wear factor into replacing a single card versus the whole deck?
