So having read the stuff about Excadrill (mainly the 1hko stuff) I think I found a decent answer to this guy in this Sp00ky pumpkin. Gourgeist has the distinct ghost typing, allowing a nifty horn drill immunity, which is fairly useful for a counter to it. Also, Gourgeist has a grass typing to sponge up most attack Excadrill can throw at it. The Ev's give Gourgeist the ability to almost always avoid a 4hko from iron head on scarf excadrill, the most effective move excadrill can use along with the ability to have a bit of breathing room in case of Iron Head flinches. Foul Play is used to 2hko adamant excadrill most of the time with shadow sneak to finish the job in case of running into a jolly one, which only have a 41% chance to 2hko. Will-o-wisp is to cripple any physical attacker that would want to switch into Gourgeist, mainly Tyranitar due to the synergy with Sand Rush Excadrill. The final slot is split between Leech seed, Toxic, and Synthesis because each helps Gourgeist cripple opponents / recover health, but any of them are useful.
