This is my super awesome dark type team. c:
Someday it will be a reality.
And I will be better than Cynthia.

Spiritomb: For obvious reasons. Normal, Fighting, and Psychich types can't touch it.
Absol: Can handle Fighting types, and with a good psychic move it can take them out. Go Swords Dance~!
Scrafty: Can learn a lot of moves and defend against fighting. Somewhat....
Honchcrow: Can take out both Fighting and Bug types.
Hydreigon: It just...just because....
Tyranitar: It's strong. c: It learns strong moves such as Hyper Beam, Giga Impact, Stone Edge, Earthquake, and Crunch. Can also learn Fire moves, Electric moves, Ice moves, and Surf.

Stuntank, Sharpedo, Weavile, Drapion, and Bisharp and Houndoom are good too!
My bro says Houndoom is garbage....
