Card Rulings

5/1/2008 The parts of the spell happen in order. When determining how many black creatures and how many red creatures you control, keep in mind that you just put a creature onto the battlefield that’s black and red.
5/1/2008 If the targeted opponent becomes an illegal target, the entire spell doesn’t resolve. You won’t get a token.
