Skarmory

Skarmory's Flying typing makes it an even more effective check than other Steel-types to all the physical attackers such as Metagross and Snorlax that rely on Earthquake to hit Steel-types. This comes with the added bonus of being hit neutrally by Fighting and Rock, too, making it an effective check to Superpower Deoxys-A and Rock Slide Groudon and one of the sturdiest physical walls in the metagame. Skarmory's utility movepool allows it to fill multiple roles by offering Spikes support, phazing, and Taunt backed up by a decent Speed tier. However, Skarmory's Flying typing makes it even more susceptible to being trapped by Magneton than Forretress, and it takes neutral damage from Latios's, Latias's, and Mewtwo's Ice Beam. It also faces stiff competition from other defensive Steel-types due to lacking both Explosion and reliable recovery. Primarily, it competes with Forretress, which offers Rapid Spin support on top of Spikes, better base HP, and Explosion.
