Moving on to the Super Rares!
Black Centaur: I think it should be added as Mid to High
Queen Lamia: Move to mid-low, its very hard to sell Queen Lamia (currently)
for even a Burnclaw Cerberus, bad stats and an average skill
Azure Dragon of Spring: Move to Mid, I don't believe its in the same class as Mikhail or Black Centaur
Red Bird of Summer: Stay, I think its fair to say its mid tier, I've had it before and have been offered Azure, Crystal Golem for it
Crystal Golem: Move to Mid-High, its definitely in the same class as Black Centaur and Mikhail
Batpard: Move to Mid, while its true that no one is offering it anymore, its also true that no one is really looking for one either, not in the same class as Mikhail and Black Centaur
