Pokémon Crystal Tips

Help getting entei and raikou
What you do is get a ghost pokemon that knows mean look, get a bunch of max, super, or just plain regular repels, and then you use the repels in a grassy area and just look places, and you MIGHT (i'm not really sure if it works) find a raikou or entei. If it doesn't work i'm sorry you wasted time and money. =-(
