Let's kick this off.
Scrafty is great, man. One of the if not, most underrated sweepers present in the tier. While it may not have the most impressive Attack or Speed stat, Scrafty more than makes up for it due to its pretty decent bulk and access to Dragon Dance. The presence of bulky, rather passive Pokemon such as Alomomola and Registeel give Scrafty plenty of chances to start boosting. Thanks to Shed Skin, Scrafty shrugs off Toxic and Scald burns like nothing, letting it boost to +6 on your ass (don't get me wrong: Intimidate and Moxie are great abilities, but they dont stop Alomomola from fucking you over). You're probably thinking "boohoo, its great STAB moves in Drain Punch, Knock Off, and High Jump Kick are resisted by Fairy types!", but luckily Scrafty has Iron Head, which can OHKO Diancie after a boost and has a high Flinch chance to let it cheese through the other fairies like Granbull (who loses its only form of recovery if it's hit by Knock Off) and Aromatisse. It also has the tools to bypass most of its checks with ease. Wanna be able to set up on Virizion / avoid being revenge killed by Choice Scarf Emboar / Choice Band Sawk? Chople Berry. Need some extra longevity and Drain Punch just wont cut it? Rest. Wanna chunk those pesky Venusaur and Golbat? Zen Headbutt (believe me, it works). There's plenty of other neat techs you could try, so give this mon a shot if you ever wanna build an ORAS team. Also Jesus Christ, guys. This guy is the literal Trifecta Slayer, 6-0's that team so hard. Why aren't y'all using Scrafty more?
