I was able to reset my password so I could log into my account on here, but the new password doesn't work on the client to let me login and play the game.
If you really want to take it to deoxys, catch a tyrogue a few routes earlier with fake out and evolve it to a hitmontop. Start with top, fake out, switch, put top back in once other pokemon faints, fake out, switch rinse repeat.
My favorite pokemon is baby Mewtwo from the movie because it's just so darn cute. That headset should be mine because I'm getting tired of my cheap earbuds crapping out on me.
The way I beat him was quite easy (after two conventional losses).
I started with Hitmontop, fake out, switch out to a pokemon that will faint, then switch back for the fake out. Really cheap but so was Deoxys.
