Nice work! Will try it out as soon as it gets more stable and the crests get reintroduced (liked the idea from rejuvenation).
Unfortunately I dislike some of these buffs though as they don't seem very well balanced. Especially those who get both a crest and another boost (like some combination of new/changed abilities and crests are very op). Don't know if that is intended or not. Especially because some other Pokémon just get pretty inconsequential changes which seems odd.
Still good job for introducing gen 8, Aevian forms and crests!
