Text (IN/10): Target creature can't block this turn. ; Draw a card.
Must be used before blockers are declared in order to affect blocking decisions. You cannot wait to see what your opponent declares and then try to stop them. [D'Angelo 1998/01/06]
You can use it after combat or even on a creature which cannot possibly block this turn because it's that player's turn to attack, but it generally has no effect other than to let you draw a card. [D'Angelo 1998/01/06]
