>>55734717In most PvE cases shadows are better than normals, but it's acceptable to purify for some megas. Most notably when your mon is at least 13/13/13 (purification adds +2 to each stat) for a hundo. But again, IVs are a meme.
Groudon has thus far been much more frequently available as normal and only this one time as shadow, so I'd advise to hold on to it.
Also the thread is autosaged? lol
