Ah, thank you. Now that's going to make masuda methoding for useful shinies way more useful...
Added the balls to the spoilers.Best balls for each of these ORAS Shiny Megas?
Hidden beneath spoilers for anyone who doesn't want to see:
Heal ball or Luxury ball?
Timer ball or if you have access to johto balls a Fast one? Good old Premier ball too
Assuming this one might be catched like we did with FS this game... Heal ball? Dream ball is really nice too but it would be a illegal ball. Both for contrast.
Luxury ball. Maybe friend ball.
Mmm heal ball? Maybe love ball or heavy ball too, again going with apricorns
