Thanks to its blistering base 115 Speed and great supporting movepool, Azelf works as the second-best dual screener in the game, falling short of only Deoxys-S. This set helps more frail Pokemon such as Sharpedo and Porygon-Z set up and begin their sweeps, as it supplies them with a temporary defensive boost from Light Screen and Reflect. Taunt shuts down opposing Taunt users, walls, and in extreme cases, setup sweepers. This can also help keep hazards off Azelf's side of the field until setup is complete. Stealth Rock is great for general team support, damaging the opponent upon switching in, and breaking any stray Focus Sashes that might delay the sweep of a teammate. Read this and tell me its not outright telling you this is a mini Deoxys-S, a pokemon that outclass Deoxys-D. Azelf is way more threatining than Deoxys-D, speed means everything simply put. Has Azelf ever been suspected for BL at least? No. What makes Deoxys-D any more ban worthy to ubers?
