azelf should stay at a-. It's pretty much the face of hyper offense, being the best suicide lead in the tier, outspeeding a large portion of offensive threats, preventing opposing hazards from being set up with taunt, and crippling a lot of the tier with knock off, and it's immensely easy to keep its hazards up due to Explosion, letting it switch into common spinners like Stoise or Donphan with a check, such as Shaymin. however, the reason it shouldn't be A is because the things that do manage to outspeed it fuck it entirely. sashzam can check it with shadow ball, and with the popularity of mega aerodactyl, which just happens to be one of the biggest fuck yous to HO in the tier and can pretty much rape azelf in any shape or form (unless you're a retard and running 4 attacks dactyl, in which case you're doing it wrong). there's also the fact that fast taunt is p popular in the current meta, with things like the aformentioned dactyl, crobat, and /especially/ that fucking (BAN ME PLEASE) sableye, you're forced to counterlead them and hope you can somehow get rocks up later in the match.
