I just bought the core set today. I will use it to play draft (like in Magic, not as in the rule book) with my friends. Therefore my question to you are: What should I buy to get a good pile of drafting cards? I will buy the delux packages (maybe not the Legends), but what else? What will be best for this draft format?
I advice You 3x Core Set, 2x Assault, 1x March and 1x Legends that should works well. Remember that core set and Assault have many important cards as singles, so You need two or three of them to play effectiv. I am old magic player and I also advice You to separate destruction from order, and if You draft with 8 players, choose at random who draft order and who draft destro, without separation drafted card pile could be unplayable or just not fun.
