Just saying the AAA LC section needs a lot of updates (esp viability rankings) since its become pretty popular.
Zigzagoon needs to go from B to like A+ at least. This thing can break through its checks without blinking an eye because it can run either Scrappy (for ghosts), Mold Breaker (for Unaware), or even shit like Sturdy or Unburden. It has coverage for its resists (Rock Smash/Seed Bomb/Thief if it isn't running Scrappy) and is the most threatening sweeper right now. Add Unburden and Scrappy to it's list imo.
Desolate Land should be added to Numel.
Regenerator should be added to Spritzee (so that it doesn't have to rely just on it's own wishes for recovery).
Aerilate should be added to Taillow, and honestly I think it should move up to A+ rank. It has a good movepool to abuse with Aerilate boosted Boomburst, Quick Attack, Return, and coverage in U-turn/Heat Wave.
Porygon should probably be around B rank, it has cool options like No Guard (it has Zap Cannon + Blizzard), Scrappy, or even Unaware. It's versatile and is super bulky + strong.
Misdreavus should probably go up to A+, and have Magic Bounce, Mold Breaker + it's clones, and Regenerator added to it's abilities. It's somewhat versatile and is very bulky, strong, and is a great sweeper/wincon/status spreader/stallbreaker.
Yanma should be in A+ or S rank. This thing is fucking terrifying, and can run stuff like No Guard, Download, Speed Boost, or Serene Grace. No Guard can be used with Hypnosis for great pivoting, Dowload can be used for potential sweeping or boosted U-turns, Speed Boost can be used for sweeping/cleaning, and Serene Grace can pretty much ruin teams with substitute + air slash + coverage.
Darumaka with Unburden + Belly Drum is pretty scary, so add Unburden to it's list.
Dratini seems pretty cool with all of the -ate abilities, so I think it should be listed, maybe B- since it's physical movepool isn't fantastic.
Surskit with Mold Breaker (or it's clones) or even Sturdy is pretty cool and deserves B+ rank.
Drilbur with Refrigerate/Aerilate should probably be like A-, unstoppable rapid spin is invaluable and hits hard with fantastic Ice/Flying + Ground Coverage.
Nosepass with Regenerator is really cool. It's extremely bulky and can pivot with Volt Switch and set rocks. It walls stuff like Fletchling (although it'll need a little SpA investment to ensure it wins 1v1), Taillow, and soft checks Doduo. Probably B+.
Doduo should be listed with Aerilate, although Taillow may be faster, Doduo is stronger, having a stronger Quick Attack and access to Knock Off.
Cacnea should be in like B, I've been trying out a Prankster set with Spikes + Dbond + Encore (to stop set up) and it's pretty effective and catches a lot off guard.
Honedge should probably be around B-, Levitate/Flash Fire/Regenator is cool but it's not an amazing mon.
Edit: Also, Shroomish/Foongus with Prankster Spore is really cool so maybe B rank or so.
