There is uncertainty in every booster pack
Ral Zarek, Guest Lecturer, and Professor Dellian Fel are both mythic rares , and given that there are only two of them in the entire set, they just about beat out the elder dragons for scarcity, although we'll have to wait to see what the market decides on in terms of their value
As the set name suggests, Dragon-type Pokemon are the undisputed stars of Dragons Exalted, but they're not the only type of Pokemon allowed into the set
I suppose a future metagame could develop where this card ends up seeing play in a deck like that, but control brews arent going to like how conditional this is and the aggro/midrange decks are skewing red
A cards condition also significantly impacts its value, whether holo or non-holo
