On my journey to the top 5, most of my views of certain Pokemon were solidified and others were changed.
Cresselia: Leaning towards "not broken". Cresselia is hard as fuck to take down, but it still loses to so many offensive threats, namely Moltres, Absol, and Drapion. Swellow + Absol is almost a foolproof counter for Cresselia without having to even prepare for it. Absol is definitely not overcentralizing >.>. On top of this, Cresselia is essentially set up bait for Froslass, who can switch in, Taunt, set up Spikes, Pain Split, and switch to Absol for an easy kill.
Porygonz: Not broken. It hurts, yes, but being locked into a normal-type attack is less than ideal most of the time. On top of this it is easily revenge kill able if it isn't Choice Scarf, and Absol, Blaziken, Hitmontop, etc revenge kill it either way.
Raikou: Undecided. I mean, I sweep (when I use it) with it easily but that's usually because other people just suck and keep Pz and non CM Cresselia in on it. It sets up on so many Pokemon and is so hard to take down, but I'm not sure if it's absolutely "broken" anymore since Cresselia can beat it. I'm still leaning towards broken. If Cresselia is deemed broken just because we follow the characteristic as a "rule", then Raikou should be as well.
Froslass. Absolutely broken; more broken than in the last metagame. This metagame is swarming with set up bait for Froslass, and the viability of Rapid Spin is becoming more and more questionable. Stall in particular has no defense for Froslass's Spikes. Spikes are almost always on the field, and they are there to stay. The one major thing that Froslass has trouble with this the omnipresence of strong Dark-types, particularly Absol, and NP Missy. However, I still strongly feel Froslass is broken.
Moltres + Swellow: When used with Froslass, they are nearly impossible to stop. Moltres in particular has 0 safe switch-ins once Spikes and SR are set up. 0! Swellow abuses Spikes with U-turn, and is a monster late game.
Absol: THE Anti-metagame Pokemon. It beats so many top threats, especially anything remotely defensive. If I'm against a stall team, I will usually sacrifice Froslass on something like Cresselia or Spiritomb after I taunt them, and simply Swords Dance and destroy the remaining members of their team without breaking a sweat. Sucker Punch works great against offense as well. The only thing really holding Absol back are fast Substitute users, who can still be beaten but they do have a decent shot of beating Absol. There are also fast priority users, like Swellow for example. Absol is just "great", it isn't anywhere near broken.
If a vote were to happen right now, I'd vote Raikou and Froslass BL, abstain on Cresselia, and vote Pz UU. Most likely anyway.
That is all for now.
