The only types this leaves me are Normal, Ice, and Rock. Grass can't be used due to a previous restriction. This leaves me with a pure Normal type or Sudowoodo. Since only STAB moves can be used (another prior restriction) and Lucario 4x resists Rock, I can only use a pure Normal type for this. No Normal type available can solo Maylene without being grossly overleveled. I'm sorry, but I have to reject this unless you change it. Unless Naix changes his challenge, I will accept one more post-Gardenia challenge!
