Hmm this is an interesting topic, they should make another tournement similar to the TMB and SSB and choose a designated pokemon for that like they did for those two. I mean I give exeggutor a lot more respect now because I associate him with the TMB. Anyway there are some other trophy cards out there that we don't know about and probably never will own, there is one in the gallery here that I think looks excellent that you dont hear too much about, here is the link,

I think there are other cards out there like this that no collector has ever owned, or at least confirmed owning, I do not know how you would gauge the price on a trophy like this since it has never been sold or really seen on ebay.
