Sounds like there's plenty of value to be extracted here! If only there were some kind of niche market where people could trade just these items, perhaps some kind of Magic: the Gathering Online Exchange.
I just checked to see if the domain name was available mtgox.com, but some weird fake money site is using it for what looks like a pyramid scheme.
Considering these pyramid schemes always come crashing down at some point, maybe we can grab the domain after them?
In other words, not an online exchange for Magic: The Gathering cards, but rather an exchange for Magic: The Gathering Online cards.
