See, there it is again with the "I CALL!!" This is not what trading in a free market is supposed to be about. Why, if you have the
Aragorn's Bow, or
Ring of Doom, or whatever hot card you can think of, would you limit your options by allowing people to call this or that just because they saw the post first? If the first person can come up enough cards that you kinda want, that trade will probably go through. But what if the next person has a couple cards that you REALLY want? Oh well, you limited yourself to only the first person in line, so you suffer the consequences.
I really just don't get it. If you've got the hot card, YOU are in control of the negotiations - whoever wants it most and is willing to give up the most should be the one you trade with. It's called market value for a reason.
