Hey! I'm new at this game so I'm thinking about spending some money in the game.
The question is: The mini-set gives you 66 cards, but some of them I got it by opening packs, so if I'm going to purchase it, should I dust that cards? I mean, for example, If I already have 1 legendary, If I buy it, It won't give me a second one of the same I already have, I guess, but If I dust it, it will give me the legendary and I'll have 400 dust. I wanna make sure it works like this!
