Soul Caliber IV (360) - Win 50 online ranked matches in a row - Cannot use Astaroth or Cervantes

I love this game, but my X-Box is currently in the shop. The, um... Pawn shop. I'm getting it back next week, though.

I got to I think 25 or so once with my custom female Kilik (black chick with wings, "Martha Jones"). I challenge someone to win 50 online ranked matches, accepting whoever you come across - whether they're level 1 or 115.

Good luck!
