Murkrow

Murkow's Dark / Flying typing lets it hit most of the metagame relatively hard with its STAB moves plus a coverage move. Murkrow can also function as a revenge killer and late-game cleaner with Sucker Punch. On top of this, Murkrow gets access to Prankster, a rare but useful ability in PU, allowing it to paralyze many of the faster Pokemon in the metagame and stop a variety of utility moves with Taunt. However, a look at Murkrow's defensive stats reveals a big downside; its poor bulk doesn't go well with its weaknesses to common attacking types in Electric, Rock, Ice, and to a lesser extent Fairy. Common Pokemon such as Rotom-F and Zebstrika can take advantage of this. Although it has good offensive stats, they are not amazing, forcing Murkrow to run Life Orb to give it the boost it needs to get some KOs. Another downside is that Murkrow is weak to Stealth Rock, and when this is combined with Life Orb recoil, Murkrow can be revenge killed quite easily. Murkrow faces competition from Dodrio, which is more potent in typing and stats, but Murkrow has Prankster as well as a much more powerful priority move, and Dodrio lacks the Special Attack that Murkrow has.
