So I knida cheated by getting someone to trade their Latias to me, but I still really need a master ball! People keep saying "win at the lottery!" but I don't understand how to do that! Is it possible? Coz I've tried (I played non-stop for 4 hours trying to get it 5 in a row!) but now I'm just confused. Can someone please tell me how to get the master ball!!
PS. I missed my chance picking it up in Team Magma/Aqua's hideout, so this is why I need to get it through the lottery.
