Gourgeist, Gourgeist-L, and Illumise to D-
all of these have the same thing in common: everything they can do is done slightly better by other Pokemon. Because of this, they should all be in the same rank. Since Illumise dropping to E was opposed on the account that it wasn't bad, just entirely outclassed, D- is where they fit best.
There are a few NFEs in the D ranks that stick out to me as being really questionable in terms of deserving a spot on this list. These are
Growlithe, Pikachu, and Porygon. I haven't used any of these Pokemon, but I can't see any reason why you'd want to. Looking at them individually:
Pikachu:
Pikachu is just so absurdly frail that I can't see why you would ever consider it over Raichu or Zebstrika, which, while also frail, actually have the bulk to take a hit when necessary. Additionally, its base 90 Speed is really mediocre for something that can't take a hit to save its life. If those flaws weren't enough, it's not even that much stronger than Raichu:
252 SpA Light Ball Pikachu Thunderbolt vs. 0 HP / 0 SpD Sneasel: 207-244 (82.4 - 97.2%) -- guaranteed 2HKO
252 SpA Life Orb Raichu Thunderbolt vs. 0 HP / 0 SpD Sneasel: 188-224 (74.9 - 89.2%) -- guaranteed 2HKO
All in all, Pikachu has absolutely zero niche, so I can't see why it should remain ranked.
Growlithe:
Growlithe's supposed niche is that it is the most physically bulky fire-type in the tier because of intimidate. However, this is really quite trivial when when you consider that Growlithe has pretty much zero offensive presence, especially when you compare it to Specially Defensive Flare Blitz Flareon, the fact that it's weak to Stealth Rock without Leftovers to passively heal off the damage, the fact that a lot of physical attackers can just hit it with Knock Off and render it useless, and most importantly, the fact that Fire isn't even a good physically defensive type. The only relevant physical attackers that it walls by virtue of its typing are Scyther, Flareon (which can even switch into Growlithe's Flare Blitz and 2HKO with a bit of prior damage if it's CB lol), and Rapidash (which is pushing it in terms of being relevant). This begs the question: Why not just use a different physical wall that has a good defensive typing and can actually hurt things in return? While Growlithe is the best physically defensive Fire-type available in PU, why would anyone possibly need a physically defensive Fire-type?
Porygon:
I don't know what this is even supposed to do honestly. Defensive sets are hopelessly outclassed by Lickilicky. Tank sets have Trace and good coverage I guess, but they're very weak and aren't even that bulky at all. For example:
252 Atk Life Orb Sneasel Knock Off (97.5 BP) vs. 252 HP / 0 Def Eviolite Porygon: 149-177 (44.6 - 52.9%) -- guaranteed 2HKO after Stealth Rock
252+ SpA Porygon Tri Attack vs. 0 HP / 0 SpD Sneasel: 136-162 (54.1 - 64.5%) -- guaranteed 2HKO after Stealth Rock
252 SpA Life Orb Ninetales Fire Blast vs. 252 HP / 0 SpD Eviolite Porygon: 144-172 (43.1 - 51.4%) -- 97.7% chance to 2HKO after Stealth Rock
252+ SpA Porygon Tri Attack vs. 0 HP / 4 SpD Ninetales: 109-129 (37.6 - 44.2%) -- guaranteed 2HKO after Stealth Rock
Overall, Porygon isn't bulky, isn't strong, and overall has no real niche that I can see. I really don't see why it's ranked at all.
Will make actual relevant noms later
Also
Froggyboy sun doesn't affect the viability of sand at all, they're completely different playstyles lol. also, stoutland is horribly outclassed outside of sand. personally I think stoutland and baby hippo should be in the same rank, but that's for another post.
