Who's Still on Arya's Kill List on Game of Thrones?

For: Killing her friend Mycah, the butcher's boy, in season one.

Has he been killed yet? No; although Arya thinks he's dead. She leaves him to die in pain, but in season six we see that he was actually saved by a group who takes him in.

Also, in episode three of season six, Arya says that she took the Hound off the list and had been confused about letting him die.
