How to get a collection of Masterballs in ORAS

So first things first, lets get real here, for those who want to catch Legendaries competitively and don't want to deal with the constant Pokéball grinding only to catch a Pokémon with poor Iv's and/or Nature would find this really useful . Heck maybe you just like to catch everything in a Masterball it's up to you in the end on how you want to use this. So lets get started, things you will need so that you can begin collecting your Masterballs. (I would like to note, you can also just go to the lottery in Lilycove and test your luck there, but this method seems to be easier in terms of luck and time.)

1) You will need a secret base, doesn't matter how big or small it is, you just need one.

2) Next you will need to at least have a bronze flag in your base, meaning you have captured 30 flags from different secret bases.

3) Look for both the guitarist(M),school kid(M, or F), Hex Manica (F), and Lass(F) Secret Pal NPC's. You must have one or both. Make sure your base only has these NPC's if you want this method to work fast enough.

4) Now here is why you need the bronze flag, according to Serebii (Source of Chart list: http://www.serebii.net/omegarubyalphasapphire/supersecretbases.shtml ) The Bronze flag will give the NPC's listed in step 3, the option/power to pick up items in your secret base. The link to Serebii's chart does list all the items you can possibly get, so check there if your looking for something else. But one of the items listed that you can get with this power is a Master Ball.

5) Finally all you need to do now, is come in every day to your base and ask your NPC pals if they can search for an item for you. Keep doing this and you will eventually get a Masterball or two.

This method does work and you can use this as many times as you want, there is no limit to how many Masterballs you can receive from this method. Anyways that is all for now, hopefully I was able to teach you how to pull this method off. If you have any questions do not be afraid to ask here or in a PM.
