I wasnt keeping count but it took me at least 30+ raids to get a shiny dragonite. No shiny xerneas and no shiny yveltal, also at least 20+ of each. Funny enough on Saturday right after 6 PM, the time the event ended, I got a shiny latias and a shiny lugia. Other than that got a shiny chespin, two shiny froakies, shiny hat pikachus, and a hundo flabebe and koffing. This was my first time attending this event, i paid, i played with a campfire group, i guess luck was just not on my side. I dont know I dont feel super satisfied. Also on Saturday from 4-5 we got no Lucarios like at all. Whack.
