So Sableye is allowed to run a unique set(posted above) but Heracross isn't?SD Guts Heracross does not run Megahorn. It runs Close Combat, Knock Off, and Facade. Megahorn is redundant with Knock Off a great deal of the time. Some people choose to run Megahorn over Swords Dance, but the SD variant is by far the most common set. This Sableye is designed to counter that.
I don't get your point. If this Sableye is common/turns out to be common why shouldn't I run Megahorn over Facade/CC instead of SD.
I mean Megahorn isn't even a bad move, it has the same basepower as Close Combat, only the typing coverage is worse than CC. If there is a major threat on stall Bug/Normal/Dark can't handle please share it.
