I have an idea that exists in a few other games (Madden ultimate team, NHL ultimate team, FIFA ultimate team, for anyone who plays those)
The idea is a trading block of sorts. You post a card to the trade block, and other players can offer any number of cards/clintz for the card. You can set preferred cards that you would like in offers, stuff like that. It is almost like an auction, except the owner of the card gets the final say, and it includes cards.
I think this would work if:
(I don't know how your examples relate/work in comparison to what I'm saying so what I'm saying may be completely off or redundant)
I was personally looking to trade "x, y, and z" card and was personally looking for "a, b, and c" cards. Would I filter the cards I'm trading and the cards I'm looking for and would get all of the trade blocks that fit my criteria?
Just curious how this would work if there were 100s of Trade Block offers for the same common (or rare) card?
Daxose, I'll give you an example:
Trade Block card - Armanda Cr
Looking for - Clintz
Now, players can offer for SPECIFICALLY YOUR Armanda Cr with the Cards and Clints you are looking for.
Or, you could do thisL
Trade Block Card - Armanda Cr
Looking for - (Not Specified)
Now players can offer anything they want
You, the player who posted the card to the trade block, can choose which offer they wish to accept
