I've been looking at Nugget Bride recently, and I've been seeing teams with 2 megas. Is it possible?
While you can't Mega Evolve two Pokemon in a match, you can technically have two Megas. You'll only be able to use one though, so it's wasting an item slot to have two Megas unless you want to be able to choose for each different match.
Hope this helps! :)
Yes, it's possible. While I've never seen it myself, my source states that you can indeed have two Mega Evolutions.
Hope I helped!
