I would like a feature that allows us to make a 1 for 1 trade of legendary cards with our group members. Perhaps this could also be done for epic cards as well.

So, for example, let's say I have an Inuit Kenny, but I want a Medusa Bebe. I can trade my Inuit Kenny to a group member, who gives me a Medusa Bebe that they have. Perhaps the trade only goes through once both parties have submitted their trade request.
