I've been going through all of my analyses to check for any changes that are needed. I've now gone through all of them and I'm happy with most of them.
I have some changes though:
Seel
-Seel - Top Tier
-Availability: Seel is catchable in the Seafoam Islands, but the best way to obtain this is from the trade on Cinnabar Island. In RB, you trade Ponyta for Seel. In Yellow, you trade Growlithe for Dewgong. Cinnabar Island seems a bit late, since you need to at least beat Koga to get there. However, Seel/Dewgong is still great because it comes at the right place at the right time. The Pokémon you are trading away is found easily in the Pokémon Mansion nearby. It will generally be caught in the mid-30 level range. Once you trade for your Seel/Dewgong, you can teach it Surf and then head back to Pokémon Mansion. It will happily beat the Fire trainers here, gaining a ton of experience as a result. If you have Seel, it should evolve into Dewgong quite quickly. At the end of it you’ll have the Blizzard TM which you can use if you like (it isn’t necessary though). Once the Mansion is done, you can head straight to the Cinnabar gym and gather experience there. At the end of this, you should have a Dewgong that will have caught up to your team (and then some, should you choose to go overboard). You now have a powerful Water type obtained with little effort to assist you through the last trainers of the game (i.e. the Elite 4).
-Stats: The best way to describe Dewgong’s stats would be ‘good enough’. 95 Special gives it great power to abuse its nice STABs, and 90 HP and 80 Defence give it a good amount of bulk. 70 Speed is decent by in-game standards and you should be moving first most of the time.
-Movepool: Dewgong’s movepool is basically the default one for Water types but it has all it needs. Surf and Ice Beam/Blizzard provide plenty of coverage. Body Slam (or another Normal move) can be used to cover Water types if you want, although there are better choices for Body Slam than Dewgong. A thing to note about Dewgong is that it has Aurora Beam and Ice Beam by level up. This is useful because it allows Dewgong to run an Ice attack without using up a TM (so you can use them on something else). However, if you have it free then you should use it on Dewgong.
-Power: When you first get it, it has enough power to beat what it needs to beat: Fire types. Once you defeat them, you’ll gain a massive level/power boost, allowing you to contribute against everything else. Conveniently, Water/Ice is an excellent type combo late game so you’ll be powering through things easily regardless.
-Type: Again, Water/Ice is excellent at the point you get it in the game. It covers most of the Elite 4 by itself. From a defensive point of view Water/Ice is a bit shaky (weak to Rock, Fighting, Grass and Electric), although this isn't really that important against most regular trainers.
-Match-ups: Blaine – You can potentially sweep him with Surf. In Yellow it is a bit more difficult since Ninetales is stronger than Growlithe and Ponyta, but you’ll definitely contribute and even if you lose this particular battle you’ll still beat all of the other trainers.
Giovanni – Surf has perfect coverage against everything except Persian in Yellow, who you can still beat if you are in good shape. Just watch for Thunder and Rock Slide and you’ll be fine.
Lorelei – This is probably the worst match-up that Dewgong will likely face. You can’t do much to each other. If you have a Normal move like Body Slam it will help you out a bit, but there are better choices for Lorelei than Dewgong. Surf is fine for Jynx though.
Bruno – You beat Onix with Surf and you can even beat the others with powerful special attacks. Machamp is probably the most dangerous thing since it is the best prepared for surviving Surf, but at a good level (which isn’t unreasonable given the boosted experience) you’ll beat that too.
Agatha – Ice Beam/Blizzard hits Golbat and Surf is sufficient for Arbok. The Ghosts are trickier thanks to higher Specials and annoying status moves. It isn’t an auto-loss situation though.
Lance – Your STABs cover absolutely everything except Gyarados. Lance is a joke match-up in RB. In Yellow you also have to watch for Electric attacks, but you have the bulk to take at least one.
Blue – Your STABs cover Pidgeot, Rhydon, Exeggutor, Charizard, Arcanine, Sandslash, Ninetales and Flareon. The Water types can be taken on, although there are more efficient choices.
-Additional Comments: With the exception of RB Squirtle, Seel/Dewgong is the best Water type in the game. It just has a perfect combination of convenient availability, acceptable power and helpful match-ups, and the boosted experience it gets from being a traded Pokémon makes it a breeze to train and also saves some experience for its teammates to use. The only thing wrong with it is that it comes later than many other Pokémon, but Water types aren’t even necessary before then. It is the late game where Water types really shine, and the game has been designed so that Dewgong arrives just when it is needed. This is a Top tier Pokémon for sure, and is highly recommended.
For Pikachu, I added Seismic Toss. I think someone suggested it when I first submitted Pikachu's entries but I didn't include it because I hadn't used it before. I have since tested it and found it to be useful, particularly before those powerful moves it gets come along (which isn't actually that long after Seismic Toss but I still think they should get at reference).
For Shellder, I slashed Bubblebeam with Surf for the benefit of Yellow players since you'll probably be getting Shellder as soon as you get the Super Rod (i.e. before Surf). Cloyster doesn't actually need Bubblebeam because it starts with Aurora Beam, which has the same power and arguably better coverage for the routes to Fuschia, but it should still be mentioned I think.
Seel's entry wasn't really "improved" per say, but I was personally unhappy with... just the way it read, which didn't seem quite professional enough for me. This is just me though, and I only made very minor changes of wording to it anyway. Meh...
Other than that I'm done with them. I hope to test out Yellow Amnesia Poliwag soon, but I have other projects going on that may get in the way of this. Not really a priority though.
