XD The luck in this game is so Farfetch'd sometimes. No, make that always. XD I like how they structured the Mega competition this time around. Not only are they giving away more mega stones, but I really like the extra prizes they give the top players. Sure, people can look at it as the game forcing more coins from us, but it's a great way to foster competition.
If they get an exclusive dungeon or cutscene that's more than enough for me XD It looks like they're grouping trios with their masters, though, so we could get a 3-in-1 dungeon or 4-in-1 dungeon with legendaries.
It benefited from a fairly recent restock, but it's still inexplicably rare, so yeah. Probably the new Animal Crossing amiibo will increase demand for it, too, but I don't know if that will translate to supply. Probably not.
