Nebula here! While I don't technically have any affiliation with any Pokémon site, I am most often found at Serebii and Bulbagarden, as well as a handful of non-Pokémon sites.
I happily battle at any tier and have no preferences as to which Pokémon I use, but seem to find myself using Fire, Ground and/or Dark types most often. If you ask really nicely, I might give you my friend code. Don't expect much of a challenge though. Recently, I have been working on a Rain Dance-centric team, with Pokémon named after Advance Wars characters. If you wish to spoil it for yourself, here's my main team:
Speaking of Advance Wars, I am a Site Staff member of fansite Wars Central (we do not talk about Shade), and write webpages for the site. So far, I have completed character guides for the four GBA/DS installments in the series. I am currently working on character name guides for the games.
