When you are building a deck, how many unique characters do you think are too many?
I understand that playing 3 x copies of each card improves the chances of drawing it when needed. I also understand that "extra" copies drawn can be used for resourcing or as a back-up for when a key card is destroyed. However, I am concerned that a significant number of unique cards (3 of each) will result in games/hands where I have nothing but multiples copies of two or three characters and nothing to play.
Do you have a "rule of thumb" or unofficial guideline number you use for how many unique characters vs. non-unique characters you use?
