Skarmory (M) @ Leftovers
EVs: 248 HP / 216 SpD / 44 Spe
- Swords Dance
- Brave Bird
- Iron Head
I'd like to preface this post by saying that this set is not a meme. It pretty much functions as a normal spdef Skarmory would, but SD serves two key functions that enables Skarm to do things it otherwise couldn't. Firstly, and the reason why I came up with this set in the first place, is to better check/counter defensive pokemon like Clefable, Gliscor, and Venusaur. Normal spdef iron head Skarm may "wall" the aforementioned pokemon, but it can't actually kill them. With SD, Skarm can easily boost up and threaten to ohko or 2hko these defensive pokemon. The second role that SD enables is that of a breaker (yes... a breaker) vs slower teams, and sort of vs offensive teams as well. Flying stab is pretty damn good, and with a strong move like brave bird, Skarm can actually threaten quite a lot. For example, if Skarm sd's vs a Lando-T, then a team of Jirachi/Latios/Keldeo/Weavile/Gardevoir can't really switch in that well. For more bulkier teams, even stuff like Starmie and Talonflame (usual Skarm switchins) take upwards of 80 from a +2 brave bird. Brave bird is key for Skarmory's raw breaking ability, but iron head is still crucial to check the things it normally checks like Clefable, Diancie, Gardevoir, and even to an extent Tyranitar. As for EVs, SD only really makes sense with a spdef set, and the speed can honestly be however much you want to creep. The above evs outspeed 0 speed M-Sciz, but you can creep other Skarms as much as you want.
