Some suggestions from me:
SubwayJ: I think that Black could be shortened a bit while retaining the meanings. Something like: "Necturine attach themselves to trees to drain the nutrients. This sometimes causes other Pokemon to mistake them for berries." The "But" in White could probably just be changed to "However" with a comma.
Gerard: I'm not sure the entries are believable, since they portray Necturine as a moth, yet it's not a Bug-type, hardly looks like a moth, and doesn't even evolve into any kind of insect-like Pokémon.
tea_and_blues: I'm not 100% sure on this, but I think that "Liechi Berry" capitalizes both words. If there is precedent one way or the other, it could shed some light on this.
Kaprikorn: I'm not sure I like "antennae" for describing trees. "Conduit" might be better.
EVERYONE: Make sure "Pokémon" has a capital "P" in your entries!
ALSO @ EVERYONE: If you got a technical critique from another user, chances are I just let that be your criticism and didn't want to repeat it.
ALSO @ the "drains energy" people in general: I'm not really sure this is the right angle. In a vacuum it would be completely fine. However, as a consequence of both winning movepools, Necturine and Necturna must breed or use TMs to get any kind of draining move. It is an odd influence that the movepools have. This is why I personally always pay close attention to the flavour in my movepool submissions; even if I make the flavour really outlandish and nonsensical (*cough* Tomohawk *cough*), at the core it follows certain guidelines.
The thread was slowing down quite a while ago, and if not for various factors, it may have been closed sooner. Oh, well. You have 24 hours from this post to finalize your submissions and label them as such.
