It took me a while to decide the colors for this card, but in the end I'm certain black/white is the way to go. After the colors were decided, I infused a bit of flavor to make it fit. Let me know if you think it should be recosted, and what you put as its mana cost.
EDIT: I forgot about Crack the Earth. It doesn't feel red to be able to destroy enchantments, though. I have altered the card slightly to make it feel much better for you, and worse for every other player.
A small change makes this card much better. (Also notice the new flavor text.)
