Chandelure

With tremendous Special Attack, a decent Speed tier, and excellent offensive typing, Chandelure solidifies itself as a dangerous wallbreaker in the RU metagame. Using Steel-types like Registeel as a wallbreaking opportunity, it finds ample chances to come in and wreak havoc. It also checks dangerous setup sweepers like Lucario and Cosmic Power Metagross. Heavy-Duty Boots Chandelure doesn't need too much entry hazard support thanks to its item, and it can weaken its checks like Incineroar and Milotic with Toxic while simultaneously strengthening Hex. Choice Specs Chandelure is a very powerful wallbreaker that nukes most of the metagame, notably 2HKOing even specially defensive Umbreon with Fire Blast after minimal damage. Choice Scarf Chandelure is a good revenge killer and strong late-game cleaner that retains usefulness against bulkier teams with Trick. However, Choice item Chandelure bears a harsh Stealth Rock weakness. In general, Chandelure struggles against Dark-types and special walls like Incineroar, Umbreon, and Snorlax, but these can be debilitated by Trick from Choice item Chandelure or, in the case of the Dark-types, overpowered by Choice Specs sets. Without Choice Scarf, it's also easily revenge killed by Pokemon like Flygon, Noivern, and Sharpedo thanks to its subpar Speed tier and mediocre defenses. Sharpedo can still outspeed Choice Scarf Chandelure thanks to Speed Boost, and Flygon commonly runs Choice Scarf itself.
