All-Stars: I don't believe anyone is really overpriced. Striker is their best non Cr card and is worth it.
Fang Pi Clang: Ryuichi, Lost Hog
Freaks: All are cheap, but if I had to pick it would be Crassus and Akendram
GHEIST: Lin Xia
Jungo: Like others said. Most Jungos
La Junta: None really stick out. Emeth and Jane Ramba maybe by a couple thousand, but both well worth it if you play La Junta
Nightmare: Kolos, Kenny. Seems they are only that high because of Cr speculation. I say Kolos is overpriced by at least 10k, Kenny by at least 5k. Totally worth it IF one actually goes Cr though
Pussycats: Maybe Charlie, but not by much
Sakrohm: To me nothing really sticks out
Sentinel: Chloe, Melvin, William!
Skeelz: Jay, Praxie, Corvus. Caelus stays. He's one of the best cards in UR. He's worth it.
Ulu Watu: Tana by about 10K, Wee Lee by maybe 5k, Lulabee
Uppers: Don't really see a problem with the prices. Jackie and Zatman are worth it
It's like what BD_subclavian said on comment #58, it's bec of Cr speculation and rumors. Many of the Jungo should not be as high as they are. I can live with some of the prices but a couple obvious ones are Ongh and Sylth (I can live with 10K each though). Kreen, Bragh, Chill and Greow are REDICULOUSLY higher than they should be. Niva is a bit high too, but to me she's not severly overpriced as the ones previously said.
