same, I'm using my Mew. He's currently level 61!I got mine yesterday. It's Timid nature, too! :D
I'm not one of those people who get an event Pokemon and never touch it again. I'm currently training my Mew along with the rest of my team in Soul Silver.
Although I did get the Mew on Heart Gold and I haven't touched it yet. But my Heart Gold is solely for Pokemon collection purposes, so...
So I just FINALLY got Soul Silver, so I missed out on Mew. I guess there's no possible way for me to get one now eh?
Last week i pick my two Mews (i've HG & SS).
I didn't pick them from delivery man because i want a good nature/iv's set, but i don't have time to do the SR (stupid work).
I downloaded about a dozen Mews with this event, all with decent natures through soft reseting. I traded them over to my Diamond game which I use for trading/breeding, and so on. If I want to use one in-game, I simply trade it to my HG or Platinum game.
I'm saving one for a competitive Uber team.
