Gulpin is an interesting case: it's been blacklisted for analysis reservation in XY and SM and I honestly don't understand the reasoning behind this decision.
The earliest mention of a reasoning I could dig up was
this from sparktrain:
sparktrain said:
Gulpin is on the list because it's heavily outclassed by other Sticky Hold users and Poison-types. Trubbish[...]is a much better choice overall, as it can restore its own Berry Juice with Recycle, can set Spikes or Toxic Spikes to capitalize on forced switches, has access to Drain Punch, and has a better Speed stat, all of which give it an actually usable niche in the metagame. As a wall with Eviolite + Pain Split, Gulpin is outclassed by Koffing, which has great physical bulk and Will-O-Wisp to cripple physical attackers and wear stuff down, and isn't easily trapped and eliminated by Diglett thanks to Levitate. Even if Gulpin tries running an offensive set, or like, a boosting set with Stockpile or Curse, you're better off with Grimer, which has a much better Attack stat, as well as comparable bulk and coverage options to work with. Grimer itself is pretty mediocre anyway; there are straight-up better offensive Poison-types to choose from, such as Gastly, Skrelp, and Croagunk, which offer more immediate power, secondary STAB, and several other advantages over Gulpin.
Now, sparktrain is onto something here: Gulpin
is entirely outclassed by Trubbish and Grimer, with its only notable niche at a glance being its access to a wide special movepool and Yawn. This mon sucks ass.
But I don't really understand why simply being outclassed is enough to make Gulpin blacklisted, in a category among nigh unusable Pokemon like Combee, Magikarp and Beldum. Gulpin is perfectly usable; you're just better off with other options. And that describes like 60% of the LC mons that DO have analyses in the dex.
For example: in SM LC, why use
Bonsly if it's outclassed by
Geodude who
in of itself is outclassed by Onix?:
Bonsly is overwhelmingly outclassed in its role as a Stealth Rock user. It is utterly outclassed by
Geodude, which boasts a better typing, better Speed, and the ability to viably run an Adamant nature, and
Onix mostly outclasses Geodude thanks to its higher Speed and much higher versatility.
Don't know, but Bonsly DOES have an analysis up on the site.
Or
Nidoran-F, who's outclassed by literally every Toxic Spikes user in the metagame and whose analysis even mentions that it's bad?
Although it has access to Toxic Spikes, Nidoran-F is entirely outclassed as a defensive Toxic Spikes setter by
Mareanie and
Koffing, which boast better bulk. Other Poison-type Pokemon such as
Foongus and
Alolan Grimer also outclass it defensively and offensively as well. As such, Nidoran-F is bad and shouldn't be used.
No idea, but Nidoran-F also has an analysis up on the site.
Or
Oshawott, who's outclassed by every offensive Water-type in the metagame?
As a pure Water-type in LC, Oshawott is outclassed in all aspects.
Staryu is a better special attacker due to it being faster and having more coverage, and
Corphish is a better physical attacker because it has Adaptability. Defensively, Oshawott is unable to compete against the likes of
Frillish and
Mareanie due to their reliable recovery and secondary typings, which gives them more resistances. These Pokemon leave little room for Oshawott to carve a niche in the Little Cup Metagame.
The list goes on and on, I don't exactly see why Gulpin belongs on the blacklist while stuff like these are perfectly fine to get short analyses detailing why you shouldn't use it. I think Gulpin should be taken off the blacklist and be available for mini analysis reservation for SM LC just for the sake of completion but I do understand that writing an analysis for an unviable shitmon is the lowest of the lowest priorities for the oldgens LC council and if this isn't feasible, I think Gulpin should be removed from the reservation blacklist for future gens (though that latter suggestion may be better brought up to the current LC council).
If anyone's able to provide a more detailed explanation as to why Gulpin is on the blacklist while the others I've listed aren't though, I'd greatly appreciate it! Thank you.
Gulpin deez nuts.
