My facedown Penguin Soldier removes both your monsters from the field, sending them back to your hand, though that piercing damage hurts me something fierce. Your field wiped clear, you are left open to my counterattack. May I proceed?
((In retrospect, it would have been a better idea to let the attacks go through and flip summon Penguin Soldier on my turn. I didn't realize you had piercing, and that I take MORE damage this way... Oh well.))
