C'est Feedback Time.
Professor Shroomish - I feel calling it the Golden Wing Pokemon showcases the wings whilst detracting the main body of the pokemon. I'm not to keen on that intention, and so I'd stick with a word or two which sums up the whole of Aurumoth. I'm more than a little sceptical on your Black entry. It seems unnatural for a pokemon with the graceful prowess of Aurumoth to be diving. Gliding or floating is much better. Even then, though, I feel you should decide on a new description; this one seems a little odd and uncharacteristic for Aurumoth. The White entry seems too ordinary. Interesting descriptions means a chance of being slated! Your Black 2/ White 2 is the only description I have no problems with.
Korski - Celestial implies space and stars, which I find unfitting for Aurumoth. Although I think the "mystery" aspect of your descriptions have the potential to become scapegoats, I'm alright with this idea for the moment. Your entries are good, but I feel you should add a "yet" before "been confirmed", to imply that it is being studied.
RabidChipmunk - I love your descriptions the most so far, good job. The "Bright Flash" description has been used too many times before however. Try brainstorming for a more unique addition to the first part of the description.
Verminator - Not too sure about these, I'm afraid. I think you're trying too hard to include the abilities. Either imply the abilities in a subtle way, or talk about Aurumoth's actions differently. The Black description makes it sound like a stroppy teenager, and the White description... is better. By the way, the second sentence on the White description should start with "Its" instead of "It".
UllarWarlord - I like the unique twist you've taken to differentiate yourself from other descriptions. Nothing much else to say.
Deck Night - Good so far, but you could include variety by describing other attributes of Aurumoth. I feel the Black entry is awkwardly worded, but I'm not sure how I can suggest to improve it.
Quanyails - Eh, too much to do with light. I think you have a knack for descriptions though (Oh, you and your big, fancy words) and so I suggest taking a new direction when describing Aurumoth.
fryfrey - Good, all-round descriptions. I particularly like the B2/W2 entry, although it does limit pre-evo art (If we decide to take that route).
