Apparently, over 6 MILLION Shiny Wo-Chien were defeated in the Raid event. So now, Shiny Wo-Chien is available via Mystery Gift over the Internet. No code, just use the "Internet" option to download the shiny snail and a bunch more Tera Shards. It lasts until September 30, but get it now before you forget!
And, don't forget, there's a Chien-Pao Raid going on right now, too. If you had something that worked agaisnt Wo-Chien, chances are it'll also be pretty effective against Chien-Pao. Grass and Ice have a lot of the same weaknesses. These Raids are actually a pretty decent way to grind some Herba Mystica for shiny hunting, if you care about that.
