702.92. Miracle 702.92a Miracle is a static ability linked to a triggered ability (see rule 603.10). "Miracle [cost]" means "You may reveal this card from your hand as you draw it if it's the first card you've drawn this turn. When you reveal this card this way, you may cast it by paying [cost] rather than its mana cost." 702.92b If a player chooses to reveal a card using its miracle ability, he or she plays with that card revealed until that card leaves his or her hand, that ability resolves, or that ability otherwise leaves the stack. You can cast a card for its miracle cost only as the miracle triggered ability resolves. If you don't want to cast it at that time (or you can't cast it, perhaps because there are no legal targets available), you won't be able to cast it later for the miracle cost. RULINGS: You still draw the card, whether you use the miracle ability or not. Any ability that triggers whenever you draw a card, for example, will trigger. If you don't cast the card using its miracle ability, it will remain in your hand. You can reveal and cast a card with miracle on any turn, not just your own, if it's the first card you've drawn that turn. You don't have to reveal a drawn card with miracle if you don't wish to cast it at that time. You can cast a card for its miracle cost only as the miracle triggered ability resolves. If you don't want to cast it at that time (or you can't cast it, perhaps because there are no legal targets available), you won't be able to cast it later for the miracle cost. You cast the card with miracle during the resolution of the triggered ability. Ignore any timing restrictions based on the card's type. It's important to reveal a card with miracle before it is mixed with the other cards in your hand. Multiple card draws are always treated as a sequence of individual card draws. For example, if you haven't drawn any cards yet during a turn and cast a spell that instructs you to draw three cards, you'll draw them one at a time. Only the first card drawn this way may be revealed and cast using its miracle ability. If the card with miracle leaves your hand before the triggered ability resolves, you won't be able to cast it using its miracle ability. You draw your opening hand before any turn begins. Cards you draw for your opening hand can't be cast using miracle.
