When you get to the end of the game and you have to catch Entei from Gordon. Entei is the hardest to catch but, I know how to catch it. Here is how you do it: Try to catch about 3 Electric types, 2 Ghost types, and 2 Fighting types. The Electric types will charge your styler, the Ghost tpes will send out little ghost that scare the pokemon you are tring to catch, and the Fighting types will double your circle power. First use a Fighting type, then use a Ghost type but , if your styler is low on power use a Electric type. Guess What? you have Entei!
