Thankfully the answer is no...The shadow card is flipped when the enemy attacks. In the case of the Forest Snare, the shadow card would just be discarded at the end of the round.
Why would you do it then you ask? Well there are times when that "burnt" shadow card loses you the game. My wife and I lost a Ranger of Ithilien in the massing at Osgiliath as a burnt card and, as a result, we didn't get very far.
