I agree with all the mons you listed, especially Krook and Escavalier. Trick Room is a pretty rare move, even with the TM, but it's really good for the whole Agate-Ametrine segment because of the sudden EV-trained enemies. Jagen Kricketune is honestly why people don't really care about the earlygame's difficulty, and I'd argue is the best non-starter Pokemon for said segment, though it isn't particularly good against Corey and Shelly.
The thing with Pokemon like Garchomp, Gyarados, is that they all come at the end of a game and fill similar roles to previous Pokemon available. Yes those three are nigh-unrivaled in their field sans legends, but In-game Pokemon isn't nearly as picky stat-wise as competitive. I don't think Garchomp is anywhere near as good as the utility the likes of Krookodile, Excadrill, and Flygon bring because he isn't around for many fights that the others contribute in. Excadrill is an ungodly wallbreaker (albeit locked behind RNG for the most part) who evolves early and packs some of the highest Attack ratings available. He can start stomping teams from Shelly, whereas Garchomp comes something like 12 badges later, and then comes at like level 30, so you have to grind it up to speed, which is something that a trained Flygon or Krookodile (Who is also a good rocker if needed) wouldn't have to deal with. Garchomp's roles can also be filled by Flygon and Krookodile. Gyarados faces the same problem as DD sweepers like Scrafty, Feraligatr, and the aforementioned Flygon exist and are more readily available. and I personally don't think Gyarados brings enough. I could understand Garchomp and Gyarados, being a dominant force if there was some huge strength gap between his contemporaries that a 'mon like Aegislash has, but Garchomp and Gyarados fill roles that could have been comfortably filled long before they arrived.
Scizor gets a pass, as while sweeping two endgame fights isn't really what I'd call top-tier (my Clefable did the same thing), he's second to Blaziken as a sweeper, and like you said comes at a relatively high level. Depending on how E19 goes, Scizor could be a late-game superpower as there are very little natural SD sweepers, and who knows when we'll get the SD TM.
I always seem to sleep on Typhlosion, mostly because I personally hate it, but to each his own. Typhlosion is a real good one-trick pony, I just don't think it's really worth choosing as a starter as he's really only average until it gets Eruption Typhlosion can certainly run through Charlotte, but I'm not too sure about post E17 Blake, as he has a lot of Fire-Resists now (I think Starmie, Gyarados, and TF Walrein) and half his team is above base 100 spd (Weavile, Starmie, Slushslash). Other than that, he's really good at double battles, and has pretty good coverage thanks to Nature Power and possibly Extrasensory.
Those days are long gone, my friend.
As someone who just started recently, I have to ask why those two aren't viable anymore? Browsing old topics for relevant pokemon for team building, I was planning to include both gardevoir and magnezone in my final teams. Are there just better options now? If so, what would they be? I didn't see an electric type mentioned in original post at all. My planned team was looking something like:
