The fact that I say about deoxys not mattering if it gets one layer up because that is a worst-case scenario. Azelf can put up only stealth rock in a best-case scenario. Against any "standard" lead, such as politoed, rotom, ninetales, then both azelf and deoxys get their rocks up but deoxys gets the opportunity to put up at least one more layer. All of the deoxys counters being talked about here are being put out there in the lead spot for the purpose of making deoxys' life as difficult as possible. If these same techniques were applied to azelf, no hazards would be up. For example, leading with a prankster taunt user or a rapid spin starmie can take out azelf without any hazards, because azelf requires a focus sash and cannot hold a red card or mental herb. Azelf must try hard to obtain these rocks, because that is the best it can do. Anything that is trying to "counter" deoxys in the lead position is at best holding it to stealth rocks. When I say "it doesn't matter because stealth rocks went up", it's because something that was designed to prevent all hazards on deoxys failed. If people weren't leading with SD terrakion and Banded Tyranitar, deoxys would be already doing a much bigger number on people's teams.
