I found a couple shiny Pokemon there looking for HA's. One happened to be a Gyarados, and I did manage to get a HA Bold Tangela that I trained into a Tangrowth. Sometimes you get lucky with the Nature and IVs they choose to give you. Also I really can't wait till they have an Event or allow Zygarde to be Shiny. Its the only Ground-type I need Shiny. Plus I'm definitely going to be either getting one with good IVs and Nature, or looking for one.
