[Pombo]

Yanmega: As many people know, I (Ephraim and Pombo) used to run a timid specsmega, and though it was broken due to the havoc it caused. It was basically a living iron ball. However, in the last days i changed to stall and discovered the yanmega is handable by a lot of special walls. Cryogo, Clefable, Munchlax, Golbat, Lickytung.... all of those can take yanmega's hits nd threaten it. Not to mention the obvious weakness to SR, which, even though can be prevented, is still present and some teams can ensure they will be layed.

Venomoth: Frail. Suscetible to spikes + SR. Lacks coverage. And, even though, broken IMO. I see it as RU's volcarona, but it has bug buzz + tinted lens to provide it "unresisted" coverage with 1 move. Also, it has instant recovery in the form of roost, and the ability to BP its boosts to PZ/Cresselia/Alakazam. On top of that, it can creep your counter/abuse mindgames with Sleep Powder. Broken.

Gorebyss and Huntail: I can say it with proud: with over 500 RU battles, i NEVER lost to a smashpassing team. Never. Ever. I always managed to beat them, in the most diverse ways. Usage should determine their tier, IMO.

Omastar: Just like Yanmega, a threat, but not a broken one. Is relatively slow and need 1 turn of setup. Ferroseed can take it all day long, and the mons i used as an option to check Yanmega can do the same to Omastar, bar Golbat.

Ok, so all those pokemon ARE threatening. You have to prepare yourself against them. But there ARE ways to check and counter them, not to mention revenge. The only exception is Yanmega who, evne though i manage to deal with most times, is almost impossible to beat with proper team support.

I would like to mention that Honchkrow and Alakazam (even though he is going to OU really soon) are close to broken, if not broken, IMO.
Honch acts pretty much as Mence in Gen IV. Specific sets can be beaten, but switch in the wrong counter once and you are damned. There are ways to play around this, of course (team preview being the best way), but its still too strong for the tier.

GUYS, DO YOU WANT A SUREFIRE TO YANMEGA? RUN SDEF CLEFABLE/LICKITUNG AND THUNDER WAVE IT. OR MUNCHLAX. OR GOLBAT AND BRAVE BIRD. OR CRYOGONAL AND ICE BEAM. OR SCARFTRES AND FIRE BLAST. OR STEALTH ROCK + A GHOST WITH TOXIC.
