Magicthegathering.com officially (or shall we call it intentionally) spoiled the first rare card of their upcoming set, Shadowmoor. When you visit their site, you'll notice a Shadowmoor booster pack on the right side on the products section. Clicking it brings you to this page which shows the 15 cards with pics, casting costs and no card text. As you'll see, there's one card that is clickable and that is the rare card on the bottom. When you click that card, you'll see this:
Great art, great ability, and splashable to both black and red decks. Both aggro and control decks can really utilize this card. Hmmm... maybe I'll use this card for my future Rakdos sligh deck. Thanks Wizards!
