Must be used before blockers are declared in order to affect blocking decisions. You can’t wait to see what your opponent declares and then try to stop them.

You can use it after combat or even on a creature which can’t 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.
