How do you get all three starters on Pokemon sapphire without trading?

1. You need safire, emerald, soul silver, or heart gold

2. What you do is as soon as you get to the first town

3. Now you need another ds [friends they might help]

4. Trade over the starter

5. You have to start the game over

6. The bad part is that you have to repeat 2-5

7. Finally your friend if he/she helped should have two starters

8. You will have the third starter

9. Catch two crap Pokemon

10. Then trade you friend the two crap Pokemon for the two starters

PS. try if you can to only teach the starters one TM it is annoying to go to move deleter then waste a hm
