These buffs look pretty interesting! I'm still having some doubts about its type, since its moveset is so weird and a Dragon/Fighting type Pokémon actually exists now. I'm probably not going to buff it too much, since it's going to be even more outclassed if it's only available at the late-game, but I'll see what I can do about it!
Some of your suggestions from the first post already got added, like the Onix one! I don't get the Parasect buff, though. I get that its 4x Fire weakness makes it pretty unviable and that, as a fungus, it likes humid places, but summoning rain is a bit weird.
I like these buffs! Pokémon like Luvdisc and Magcargo need all the help they can get and I totally missed things that make perfect sense, like giving Ninetales Morning Sun. I gave the Koffing line the Fire type because their gases are very flammable, which is why they have the whole explosion theme. Wigglytuff got Fur Coat since most of its Pokédex entries mention its fur, and I'm contemplating replacing it with Fluffy once Gen 7 gets released. Also, while it's nice that most of your buffs are small and sensible, some of them are too small, like the +5 Speed boost on Donphan.
I don't think Venomoth works as a Bug/Psychic type, since learning Psychic moves is kind of a butterfly thing in Pokémon and it's all about venomous scales, and, while Serperior can be quite game-breaking with Contrary Leaf Storm, without it it's probably one of the worst starters, so I don't know what to do about it.
By the way, was the Delibird buff supposed to be +25 HP or is it actually +205 HP? It's a junk rare Pokémon, so it does need very large buffs. Giving it Chansey's HP stat seems a bit... radical, though.
I considered Dark/Fairy Zoroark too, actually! But, since I gave the same type to Absol (and by extension Mega Absol), I thought that Zoroark would get outclassed pretty badly. So, I gave it the Fighting-type, since it has ninja elements and is meant to be a Lucario counterpart. The other Dark/Fighting types are all slow, bulky physical attackers, so it's pretty unique when compared to them!
