How to catch Poké mon Silver Edition Three Beasts?

After releasing the Three Holy Beasts, enter the top lawn from the left passage (remember to put the hypnotic and fast Poké mon in the first one, such as Haunter), where you are likely to meet one of Shuijun, Leigong and Yandi. Be patient here, and don't give up until you meet thirty or forty times.

After the meeting, if you don't catch it, open the picture book, check the position of Shuijun, Leigong or Yandi, and follow it.

You can text me if you have any questions, and I will answer them one by one until they are solved.
