Blacephalon

Blacephalon is among the fastest usable Fire-types in VGC, and its access to Beast Boost and Heat Wave can allow it to sweep through weakened teams.

Blacephalon has enough Special Attack to deal serious damage, even before a Beast Boost

Ghost is a good secondary offensive typing that allows Blacephalon to hit Cresselia and Tapu Lele hard and avoid Fake Out, with the exception of Scrappy Kangaskhan's Fake Out.

Blacephalon's defenses are pathetic, with most strong neutral hits at least 2HKOing it.

Blacephalon has a poor offensive movepool that mostly limits it to Fire- and Ghost-type coverage in addition to a Hidden Power, so it'll almost always be walled by something.

Blacephalon becomes much easier to handle when rain is up, which is fairly common in VGC.
