Tap two untapped creatures you control: You may put a creature card from your hand that shares a creature type with each creature tapped this way onto the battlefield.
Rulings:
- 10/4/2004 For this to be useful, either both creatures have to have a common creature type that the one in your hand also has, or the card in your hand needs to have at least two creature types so each tapped creature can match a different one.
