So I recently realized that L’Kian can give you cards from your entire faction, not just ones you have in your deck. So my questions are:
Do these random cards have to be owned in your collection, or are they plain random, resulting in anything from your faction, owned or not?
When you replace a card got from L’Kian not normally in your deck, does that card get added to the deck and can be drawn later?
If you get a card you have in the deck, say a Makantor, while you already have 3 in your deck, do you essentially get 4?
