When you activate a 《Shadow Dragon》 Extra Card from your hand, you and your opponent place the top card of your decks in your Drop Areas.
Choose 1 black 《Shadow Dragon》 card in your hand and discard it : When this card attacks, draw 1 card, then switch this card to Active Mode at the end of the turn.
When your life is at 4 or less or 7 or more black 《Shadow Dragon》 cards are in your Drop Area : You may draw 1 card, switch up to 1 of your energy to Active Mode, and flip this card over.
