Skarmory

Skarmory's impressive Defense and great typing let it check the many physical attackers in the metagame. Skarmory has the movepool to support its team with entry hazards in Spikes, phazing in Whirlwind, and passive damage in Toxic. Sturdy allows it to get a desperation move if the situation calls for it. However, its subpar HP and Special Defense mean it crumbles to practically any special attack. Skarmory also struggles to fit all of its good utility moves and thus is often extremely passive, relying on Rocky Helmet and Body Press to deal any damage. Skarmory's Flying typing is a double-edged sword, making it neutral to Fighting and immune to Ground but a target for Electric coverage such as Zekrom's Bolt Strike and Xerneas's Thunder. It also faces stiff competition from other defensive Steel-types. Necrozma-DM checks Xerneas much better, Ferrothorn is a less passive Spikes setter and answers Kyogre, and Corviknight can be used as a Defogger.
