That's a really creepy pic. I wish Wizards could print animated GIFs on cards.

It doesn't seem to make sense flavorwise. Shouldn't it at least have defender?

I'm not a Dr. Who fan, but weeping angels can only move when nobody is looking at them, correct? I feel like there's probably a better way to portray that mechanically.

Maybe can't attack or block if a spell has been cast this turn. (casting spells shows someone watching, or maybe the reverse.)
