Skarmory

Skarmory's great defensive typing with eight resistances and two immunities, an immense Defense stat, and a fantastic utility movepool allow it to differentiate itself from other walls such as Cyclohm and Pyroak. Skarmory is able to naturally withstand potent attackers such as Mega Pinsir, and thanks to Sturdy, it is often able to stop many setup sweepers that other walls would fall victim to. Whirlwind, Defog, Spikes, Stealth Rock, and Taunt are all great support options that showcase Skarmory's role as a team player, and reliable recovery via Roost is able to keep Skarmory in top form throughout a match.

However, while Skarmory has the tools to be a great physically defensive wall, its subpar HP and Special Defense do leave some things to be desired. Common special attackers such as Volkraken, Mollux, Heatran, Cyclohm, and even Stratagem all have the power to force Skarmory out or outright defeat it. Even powerful neutral special attacks from the likes of Keldeo and Gengar can wreak havoc on Skarmory. Magnezone not only threatens Skarmory with its STAB moves, but can also trap and eliminate it from the match altogether. Fast Taunt users, such as Thundurus and Tomohawk, can also stop Skarmory from using its great utility moves, rendering it almost useless. However, Skarmory's Steel typing allows it to get past many Fairy-types, even those that are special attackers.
