When I first started this meta I ran Aero as my lead, mainly because thats what I ran in Gen 4 consistently (I swapped around between him and Machamp, and sometimes Crobat). Hes just so effective its hard to pass him up.
I found often that I could cause rage quits with in the first few turns running Aero, using taunt, stealth rocking, and getting a kill, and still hitting hard on whatever they send in next. He gets ruined by priority but he still does his job fine. I have had games where my Aero got rocks up, stopped the opponents lead from setting up, and still got 2 kills in due to flinch hax.
Im sure this is basically old news for someone who ever used an Aero lead, or even faced one... but I still am surprised by how successful he really can be.
