To get to Team Magmas base you got to go to Mt.Pyre and go to the top of the mountain and battle team aqua grunts after that Team Aqua will steal the two orbs, you talk to the old lady and guy and they'll give you a Magma Emblam. After that go to Lavridge Town where the 4th gym leader is. You go in the place where that guy is going up and down.When you get in it your screen will shake and something will break and it will be a cave, go in it and fight all the Team Magma grunts. After that go where there leader is (Maxie) you'll see him and talk to him he will be looking at Groudon and use a blue orb on him Groudon will fly away because Maxie didn't use the Red ord. After that you have to battle Maxie but be sure to say your game before talking to him and battling him. Be sure to have strong pokemon so you don't lose, and be sure to have a Escape Rope so you can get out of the cave faster. Go back to Lilycove Town and go in the Team Aqua cave the two grunts that were blocking the way they will go away. Now you have to get a chance to get the master ball so you don't have hard time catching Rayquaza,Groudon, and Kyogre.
