Harry Potter and the Chamber of Secrets

This deck is themed around the second book in the Harry Potter series, and tries really hard to choose cards that Voldemort would put in a deck if he were entering a local tournament.

The flavor revolves around the Chamber of Secrets, a secret stone chamber deep underground, in which was a basilisk. I managed to score a quick 1-on-1 with Voldemort for some Q&A time:

-Who built this place? It's rather labyrinthine.

The Architect of course.

-You seem to like snakes.

Indeed I do. That's why almost all my ice are snakes.

-This is a pretty dark deck. Bad Times, Snatch and Grab, Subliminal Messaging... you took cards that are themed after innocent corporate fun and made them legitimately terrifying.

That's what I do. I'm evil. I'm Lord Voldemort.

Comments and suggestions on ways to make this more evil/playable while keeping with the theme? Justification necessary :)
