Probably Ravenclaw. I'm not evil or heroic, so it's the toss of a coin between Ravenclaw or Hufflepuff - but I think I'm intelligent enough to sneak into the former
Pottermore sorted me I to slytherin and to be honest, I would probably agree, I wouldn't call myself evil... But my ambition sometimes gets the better of me...
Loyalty from hufflepuff (though that's about it), cunning and ambition from Slytherin, a need to prove myself and relative bravery from Gryffendor, and cleverness and wit from Ravenclaw.
