How do you capture Mew. I know it's in the Ranger Net as a mission, but..

Well you better get friend Pokemon with you... Helpful things: try to make your circuling speed faster... You need that. And have your minun or plusle charged all the way up to the fourth energy bar. Thats all you need. But you have to get your speed up really fast... Thats it!

Actually, I just recently caught MEW by using Shedinja up by the Jungle Relic.

Simple, really, and I found this out at my own expense. Try this:

1. Find out where Mew is.
2. Avoid going into capture mode with Mew (see Part 6)
3. Go To the place where there is a big slaking and a Ghost bug thing(Where you enter the temple)
4. Catch the ghost bug.
5. Go to the area where Mew is. If you don't know where it is, talk to the people and If they Say 'Mew!' Or 'mew is so cute!' or anything that describes it, It's in that area.
6. Engage capture with Mew, But go fast and capture all other Pokemon first so that Mew is the only Pokemon left to catch.Once Mew's the only one left, Get out the ghost bug poke assist. Use it, and You'll capture Mew with ease. Just circle it fast, and a bunch of ghosts will grab it. On a side note, This is the last ranger net mission...

Hope I helped!

Ps:You do not need a fast hand for Mew's capture. You just need to be able to move your hand in a circle like this:

You got to be patient. I went all over the place chasing him. When you get to an area were he will be a (!) mark will show up on top of your caracter's head. When battleing him I used a Ghost tipe. The thing is you have to be patient and wait 'till he's in the middle.
