Cards in your hand may be used as shield cards with 2 shield icons. When you use a card this way, remove it from the game face-down. As an interrupt your opponent may have you turn the card face-up, if it is a card with 2 printed shield icons, deal 1 unpreventable damage to a unit. If not, cancel that card's shielding effect. (Limit three times per phase.)
