Arya Stark, the Faceless Heir

First strike, deathtouch.

Whenever a creature dealt damage by Arya Stark, Faceless Heir dies, exile it with a Face counter on it.

{2}{u/b}: Arya Stark becomes a copy of a card exiled with a Face counter on it, except it has first strike, deathtouch, and this ability. Activate only during your turn and only as a sorcery.
