Definately agree with Galbia's post. STAB BoltBeam Coverage, Access to a typing which let's it wall the (probably) most used Stealth Rocker in the tier as well as an above average Power, mean it really does deserve a rise. I also agree with Swanna rising. A powerful offensive defogger with coverage to ruin balance (hazard setting) teams is invaluable at times, its suffers from being frail, but honestly you only ever Defog when you are forcing a switch, so it isn't a big deal. Scald Burns + Hurricane Confusions are some good secondary effects for its main STAB combo too. I'm just gonna throw out some nominations so this post isn't a useless as fuck dicksuck.
Machoke ==> A+
Fighting + Knock Off coverage in this tier ruins teams. Whether you are using the fucking annoying Dpunch set or Guts CC, this thing breaks down walls. It's final two slots can be
dedicated to luring its perceived counters or just some priority if needed. I've used Thunder punch and Heavy Slam to lure Pelipper / Clefairy respectively, and although the later is really quite niche, it fit my Clefairy weak team perfectly. Machoke switch ins in this meta that can take it on effectively are in essence non existent. The counters for each set differ, as a result a lot of scouting and risky pivot switching is required. Machoke is also one of the most splashable mons in this meta, it isn't quite Throh splashable, but its a great successor to that broken piece of shit.
Klang ==> B+ / A-
This thing really thrives in this meta. With Mega power houses running the tier like Stoutland and Dodrio, having a good normal / flying resist is crucial in this meta. Klang fills that void perfectly. It's great mono-steel typing, good bulk with Eviolite and access to shift gear make it one of the most underrated mons we have at the minute. Most peoples counters for this are either Stunfisk / Frail Water or Fire like Floatzel or Simisear, so as the game wears on, its bound to get much much more scary. It was also majorly buffed when 2 major counters to it, Poliwrath and Torterra left this tier. Ability to settup on THE S rank Mon is also a boon, its certainly higher than B rank at the minute.
Final One is a bit more subjective
Beheeyem ==> B
It might just be me, but I feel like this Pokémon is really undervalued at the minute. Sure its frail(~ish) and slow, but that doesn't detract from the fact
it doesn't have switchins. Between Psychic , Signal Beam and Thunderbolt (+ HP Fight / Ground if you hate the mediocre Probopass)
literally nothing switches in. The set I have been using was Timid Specs Analytic to somewhat overcome the speed issue. But this thing is so fucking strong, switching into a Psychic is a tough ordeal
even for "resists". Vs Offense teams (which is the meta right now I know) its kinda dead weight, but the fact it has the potential to KO anything that comes across its path, or resisted or not, makes me really enjoy it as a Pokémon.
Other things I want looked at is Scraggy (BU Rest Scraggy has like, 1 viable fairy to full on counter it) and Krokorok (Mon with no switchins #2 as
Detect Marowak can testify.) But I CBA to write up a full report :D
