B+ -> A-/A
I feel like, even though this nom was stressed a while ago, that the metagame has only gotten kinder to Infernape as of late. This is a mon that benefits from both the Conk ban and Mega Swampert's exit from the tier, as it receives less competition overall as a Fighting type as well as loses a very solid offensive check to it. Its speed tier is very, very coveted at the moment, being able to reliably don a Choice Scarf to kill Pokemon such as Terrakion and Krookodile and dent mons like Latias and Mega Aero. Infernape is also the most versatile Fighting type in the tier, being able to threaten traditional Fighting checks such as Togekiss (Gunk Shot) and Gliscor, as well as Fire type checks such as Primarina, Volcanion, and Mega Blastoise. It also, as an added touch, is the only viable Fighting type with priority, giving it the ability to finish off mons like weakened MAero and others. Overall, Infernape's versatility, ability to threaten fire and fighting checks, and consistent matchup against offense and balance make it worthy of A- rank.
