I had a shiny Groudon on Johto (which you can see in my third party slot in the screenshot). I got it from a crate. I can't really remember much about its stats, other than a -attack nature, and a very low attack IV (it was probably 0) It had 31 in 3 other stats which I can't remember. When I tried to fight a mega Latias, it didn't appear in the switching pokemon screen. Sometime between losing to the mega Latias and claiming an egg from a ranch block, an egg replaced where my Groudon was. I searched through all 100 boxes in my PC, and the Groudon wasn't there. I used the search function as well, and it didn't appear. Is it recoverable?
