If you were able to pick on ability what would it be? Why?

[popintarts]

I would want the power to duplicate because then i wouldnt have to do my homework  

[adrena_extermina]

I want the ability to be time travel or control things by mind and be good at figures or Mathematics.

I think others tend to like the abilities related to powers because we want something instant like we could finish something like magic.

Remove tumors and repair broken bones and torn ligaments.
