Hey, sorry it's taken me this long to respond (I've been consumed by this Pikachu hunt lately). EdDaBoss responded to you on my wall with pretty much what I would have said. Here's what they posted, in case you didn't see it:
"1)Get a false swipe user
2) Get a trevenant with ha harvest, skill swap and trick
3)Lead with Trevvy holding Leppa berry, then hit skill swap and trick
4) switch to op false swipe Pokemon and get it to 1HP
5) use adrenaline Orb to get it to call for help
6) wait and kill it's non-shiny friends."
This is the same method I use, although it can also be replicated with an HA Exeggcute/Exeggutor knowing Skill Swap and Bestow. I prefer Trevenant, though, since Bestow fails if the opponent is already holding an item, while Trick works either way.
