But when they only ever come up as a SDCC exclusive it can be heartbraking. However, in the end I just get over it, I'll probably never get a Phoenix or Shazam minifig, but at least someone will. In the end of the day, I can collect Marvel/DC minifigures which I never thought would happen 2 years ago.
As I said before I don't understand why these figs can't be realeased without the backing card later. Look at Superman - he was a comiccon exclusive and now you can get him for peanuts in the Luthor set, does that mean the Comic con ones are worthless. Superman with backing card $150-$250 without $10? I'm pretty sure it's exactly the same figure but it's the packaging that makes it valuable.
it's the same principle as other carded toy figures. without the card they are "common".
I'm really only fussed about Venom and it appears he will be coming out as a fig in another set anyways. :)
