Nobody is going to believe me, but I always succeed in catching Pokemon in Pokemon Diamond after complaining on an instructional YouTube video. Today, for example, I was on YouTube and commented on a video that explained how to find Meowth in Backlot's trophy garden. I turned off my DS, watched a few more YouTube videos, and then turned it on again to go back to the garden. The first Pokemon I ran into was Meowth. This is the fourth or fifth time it's happened. I go to YouTube videos to say "I'm having trouble catching [a certain Pokemon]," then play for 5 more minutes and catch it.
