Its not what its how you control your Pokemon. I beat Steven with my own Pokemon not LEGENDARY Pokemon regular. As long as you train them right it should work out.
This depends. What Pokemon are you trying to defeat? Try to get all legendary Pokemon.
After you get your 7th badge go to the lake. Then to the side of hearthome city that have Mt. Coronet and go to the top where the ruins is. Beat the two people and beat the boss and the legendary Pokemon will be waiting for you.
beat all the gym leade(not including the elites)and you should be able to unlock finding a legendary Pokemon
