80 Atk Golurk Earthquake vs. 252 HP / 0 Def Blaziken: 336-396 (92.3 - 108.79%) -- 50% chance to OHKO
(336, 338, 342, 348, 350, 354, 360, 362, 366, 372, 374, 378, 384, 386, 390, 396)
A lot of things blaziken can't OHKO. Those are the things that can revenge kill him. Golurk can NOT counter it directly since it can't guarantee survival against 2 blaze kicks. It also can't guarantee an OHKO against a bulkier blaziken build.
