Arya Stark.

The yet to be, assassin in training for the many faced god?
A good woven illusion magic can be a powerfull thing, in the hands of a decent fighter.

The most powerfull blow? the one you dont even see comeing.

Arya and Jaqen are definetely lethal, but i was unsure of how to rank them, since assassination is a different skill set.
