Rotom

Unlike its appliance counterparts, Rotom doesn't have access to any special moves and it remains a Ghost-type. Rotom's defenses and Special Attack are also lower than that of the appliances. Rotom's Ghost typing is a blessing in disguise, as not only does it grant Rotom an immunity to Normal- and Fighting-type moves, but it also renders Rapid Spin's effect useless. In place of its lower defenses and Special Attack, Rotom has higher Speed, allowing it to outrun faster threats, such as positive Speed natured Moltres. Rotom's support movepool isn't too shabby either; a combination of Trick, Will-O-Wisp, Pain Split, and Volt Switch can royally screw the opponent while aiding Rotom's teammates in sweeping. Rotom is unpredictable, and if you're not prepared for it, you'll be in for a shock.
