FINALLY! After God knows how many months spent in the swampy area of Y, between horde hunting ekans and RE'ing carnivine, and months after I got ekans, I finally got my shiny carnivine! And it was male, like I was hoping for, since James's carnivine sounded male even though its gender was never 100% confirmed. At least now I've knocked another pokemon off my Team Rocket shinydex list. Now I'm going to put AlphaSapphire to rest for a while and horde hunt on Victory Road on X and Y at the same time so I can hunt for lickitung, and I'll keep a basculin with soak in the front in case of a shiny geodude in a horde (I've found success with making geodude a water type with soak to lower its vulnerability to magnitude).
