Waiting you at Mt. Silver's top.
Last year, I released Overstrat, a website dedicated to Overused tiers of all generations and designed to serve as a tool to support the player through his teambuilding process. It is mainly in french, but an English section is now available for the main feature of the website.
For each generation (not all of them yet actually because I'm still working on it, but at least for RBY, GSC, ORAS, USM & SwSh), I made tables like the following one for all the common Pokemon in the OU tier. As an example, here's the one for Kartana in gen 8 OU :
I think it is rather self explanatory, but here are some in depth explanations for each rows :
- Common counters : these are Pokemon, OU by usage (or sometimes really close to), that can come in on whatever move of whatever set, even considering the worst rolls possible for them, and still win the 1v1. The only things I did not took into account are haxx (crits, flinches etc.), sleep inducing moves and moves like Destruction / Explosion in old gens. This row is always exhaustive.
- Unusual counters : same as before, but for non-OU mons. This list only shows the best options and is non-exhaustive in some cases for obvious reasons.
- Checks - Revenge Killers : the best Kartana's checks and revenge killers of the metagame, either for their good speed, priority or typing. Some of them can even counter some Kartana's sets, but not all at once. Tangrowth can often counter Kartana but is not on the counters' list because it has to rely on the bad accuracy of Focus Blast to get rid of it before being 2HKO'ed by the Life Orb version.
- Ideal teammates : some teammates' suggestions ; this could be because of their good typing synergy (Tapu Fini), combos (Rillaboom grass core or Slowbro Future Sight + Teleport), utility (Tyranitar that always counters Zapdos, Moltres, Latios (without Aurasphere), Dragapult, Volcarona etc.)... you got the idea.
If you put your cursor on Kartana's image, it displays its Base Stats :
The same principle applies for the underlined speed IVs ; you'll get the speed value at +0, +1 if the Pokemon is helding a Scarf, +2 if it is able to boost its speed :
For defensive Pokemon, things are a little bit different for the first 2 rows (common and unusual counters) since there's generally a plethora Pokemon that are technically able to come in and counter them.
So if we are considering Blissey's case, you can see that I only put the very best options, i.e. Pokemon that are not affected by statuts (poison and paralysis in Blissey's case), or at least not too much :
- Ferro, Skarmory and Corviknight can be paralysed but are already pretty slow and can recover, thanks to Leech Seed or Roost for the former two.
- Excadrill resists both statuts, can come in, SD and win.
- Aegislash can be paralysed but is also slow and can freely boost on it since Blissey can't touch it.
- Melmetal can OHKO Blissey with its banded STAB.
- Clefable isn't affected by Toxic and even though paralysis can be annoying, Seismic Toss is only a 5HKO, and Clef can set up CM to put pressure on Blissey.
As you can see, I did not put Gengar on the first row even though it is a great answer to Blissey, just because taking T-Wave can be too troublesome for the rest of the match. The rest of the Checks & RK list followes the same principle, all of the Pokemon being too vulnerable to paralysis and/or poison.
You can access to those tables from the website main page : here, simply clicking on the English flag
Or from there for every available generation :

SS - http://overstrat.free.fr/fiches-en/ss-en.html (the first group of 47 Pokemon is up to date with the Crown Tundra DLC and the recent Magearna and Cinderace bans)
If you have any question, feel free to ask. I'd be happy to give some more explanations if needed.
PS : on a side note, the website looks much better on computer with tables like these due to the reduced size of phone's screens.
