"[spoiler] How to get event exclusive z Crystals"

On the second island in the Tide Song Hotel, take the elevator to the 3rd floor and go to the first room to your left, talk to the man in the room. If you show him a mew you'll get the mew z crystal, if you show him a marshadow you'll get a marshadow z crystal and if you show him a snorlax you'll get the snorlax z crystal from the SM early launch event. via /r/pokemon http://ift.tt/2ia9J6M
