Best attacker in the metagame, 2HKOes almost everything with good prediction. Stealth Rock weakness can be overcome via priority Substitute and Roost. Excellent revenge killing capabilities due to STAB Sucker Punch, and can become a dedicated revenge killer with Choice Scarf. All-around the most powerful offensive Pokemon in the metagame.
RestTalk Chinchou is one of the best special sponges in the metagame, being able to wall Staryu and opposing Chinchou, as well as being one of the few good Murkrow counters. Paralysis is an excellent status to spread, while the burn from Scald is also nice. Heal Bell is rare, and Chinchou is one of the best users of it. Volt Switch is also a fantastic move. However, it is weak to Ground-type attacks, and defensive sets can be setup bait for some sweepers, such as Scraggy (although they still fear the burn from Scald).
Gets the coveted Recover, allowing it to indefinitely wall many common Pokemon in the metagame. Its naturally good defenses, combined with Eviolite, makes it almost impossible to 2HKO. By Tracing Prankster, Porygon is likely the best Murkrow counter avaliable. Thunder Wave is again a great status to throw out, and Tri Attack (as well as a plethora of other offensive moves) hit hard even without investment. However, it is weak to the common Mienfoo and Scraggy (although the former will not enjoy Thunder Wave) and is walled by Steel-types.
"Mienfoo is a shitty Pokemon."
