>>49474418Yep. Easy points and easier capture. Telling you this now because if you catch them without completing the Dex entry you'll just have to track them down again and do it later if you ever wanna get the shiny charm, which I'm in the process of doing.
>>49474422I found mine in this tree, good luck.
>>49474437Each zone has different distortion spawns, you just have to get one in each area and see what you get from them. Mirelands tends to have Porygon, Coastlands tend to have Magnemite and Magneton, and Highlands tends to have fossilmons. Eeveelutions, normal Sneasel, and the occasional starter are also possible.
