you actually play pokemon.. so sad.
After you defeat the dragon type gym leader, go to the route to Pokemon league you will be stopped by the professor and she will give you the Master Ball.
Go to Dragon's Den. Talk to the Dragon Den Master, which turns out to be Clair's grandfather. He will ask you some questions. If you get all the questions right (I forgot the precise answers at this moment) then, if you visit him later, will give you an ExtremeSpeed Dratini. Regardless of whether you get all the questions wrong, he will still give you a Dratini. Exit Dragon's Den and Clair will finally award you the Rising Badge, and TM59 (Dragon Pulse). Now you're ready for the Pokemon League!
after you beat the eighth gym it is simple. go to the dragon's den and answer the elder's questions. then Clair comes and she will give you the eighth badge. after that go to new bark town and go to the lab. professor elm will then give you the master ball.
by completing all the gym battles in johto( then finding the dragon fang) and you will get a phone call from prof elm,fly to his lab,then he will give you a master ball,to get more balls equip a Pokemon with a master ball and duplicate that Pokemon
if you give it to a pokemon yhat has dragon attacks its power will increase
you give it two a Pokemon that knows dragon type moves.
Unfortunately, Clair won't give the badge directly since she thinks you don't deserve it. So you surf to the back of the Gym (Dragon's Den) and surf to the left, never mind the battling trainers. You go down the stairs and surf again, and go to the entrance of the Dragon's Den. Talk to the Master (Clair's Grandfather) and answer questions truthfully. Clair will then come in and ask if you failed, and her Master forces her to give you the Rising Badge. When you come back to the entrance of the Dragon's Den, Clair will talk to you and give you TM Dragon Pulse. She will then tell you how to get to the Pokemon League.
Your dragon Pokemon has to love you, keep training it or give it rare candys
Clone your Pokemon and give them the master ball
give one to a Pokemon and trade the Pokemon with the master ball.
Well once you beat the game you can give master ball to one of Pokemon that you trade then you will have 2. Or you could copy your Pokemon in emerald when there holding masterballs then give the master balls to your real Pokemon and trade them over!!
first you get amaster ball give the master ball to Pokemon copy that Pokemon over and over again then take the master balls from the Pokemon
