I have been breeding pokemon for competitive battling on the DS wi-fi for the last few weeks when i read on a different site that a majority of competitive battling is done on pokemon simulators that can be downloaded off the internet. It says that it is a simplified form of the game in which you can get perfect ivs, evs, and natures to create the perfect pokemon and teams that would be near impossible to get in the actual cartridge games. My questions are: Is this true? And if so what is the newest and most used simulator that i should download.
