where do the crystal and pearl versions of tfg figures come from? i have a few tfgs and know they're rare in general but i don't know much about how they were released or how you get the crystal/pearl versions? were figures just released in blind packs with a chance of pulling one? and do all the tfgs come with an alternate version or just some? i found this recently and was considering buying it but it costs $150 and that seemed too high. what's the going rate for these guys?
