I am needing some assistance in deck building. My curiosity comes in the form of determing how many multiples of a card to have in the deck. I know that I'm not allowed to have more than (3x) any card that has the same title (unless restricted by the text in the textbox of a card). But I'm curious to find out people's strategies when including multiples of unique cards (specifically characters) in the deck. One thought is to include 3x a unique for a higher chance of reveal, plus it gives you a chance to have a "Dummy" card drawn in case you lose an intrigue challenge. The only downside to that is that if the unique ends up in the dead pile before you have a chance to dupe it, you're left with 1/2 cards that are useless except for having a Dummy card in your hand for intrigue challenge fodder. The flip side of that being that if you only include 1/2x a unique card then you greatly reduce your chances of drawing that card into your hand, but you maximize it's effectiveness when you do draw it.
Where do you stand on this issue and why?
