Murkrow

Murkrow is a potent wallbreaker in PU. It can hit most of the tier neutrally with its coverage and can be difficult to switch into with Brave Bird. Sucker Punch is helpful against offense as well, preempting threats like Magmar that outspeed Murkrow naturally. While extremely frail, Murkrow does have a sliver of defensive utility in the form of Insomnia, letting it aggressively switch into some of the tier's Grass-types like Tangela and Victreebel, which use Sleep Powder. However, this is rather risky. Murkrow also struggles with sustainability between Stealth Rock, Brave Bird, and Life Orb recoil.
