You can purchase packs from the game with your hard earned cash but you can't buy cards from other players. I won't spend a dime on this game if i can't do what i want with what i have. Edit for clarity: if i buy MTG cards i can sell them or buy singles for other people or vendors. Why can't we do the same here? If i want to a single mythic for another player, why can't I? I rather pay him $20 for that card instead paying you $100 and never even pulling a single mythic much less the one i want.
