I saw on the wikipedia page that Pokemon from the honey tree have a
big chance of being shiny, but I want to know if that information
is up to date since I haven't see any screenshot proof of it being
on the up-to-date artwork and I've been trying for a good 2 weeks
to get a shiny from that tree and I haven't yet..
Although it's still kinnda luck based in my opinion, even if it is
the easiest way to get shiny's. You do need to keep at it and I do
recommend using Super Honey to speed it up a little (Super Honey
makes Pokemon appear faster and more frequent).
