Fraxure

Fraxure possesses a high Attack stat, which, along with high-powered moves and good coverage, makes it remarkably hard to switch into. Additionally, Fraxure's access to the coveted Dragon Dance allows it to threaten offensive builds. Fraxure's useful mono-Dragon typing gives it resistances to the common Electric-, Fire-, Water-, and Grass-type moves thrown around the tier, and base 67 Speed is enough to outspeed most defensive Pokemon. On top of all this, Mold Breaker allows Fraxure to ignore abilities such as Sturdy, Solid Rock, and Unaware. However, Fraxure is quite frail, even getting 2HKOed by strong resisted hits and relying on Eviolite for any sort of bulk. This can make it difficult for Fraxure to set up and sweep at times. Furthermore, Fraxure's Speed stat isn't the best, as it gets outrun by most offensive Pokemon without a Speed boost including Tauros, Archeops, and Jynx.
