Blitz represents three abilities: two static abilities that function while the card with blitz is on the stack, one of which may create a delayed triggered ability, and a static ability that functions while the object with blitz is on the battlefield. “Blitz [cost]” means “You may cast this card by paying [cost] rather than its mana cost,” “If this spell’s blitz cost was paid, sacrifice the permanent this spell becomes at the beginning of the next end step,” and “As long as this permanent’s blitz cost was paid, it has haste and ‘When this permanent is put into a graveyard from the battlefield, draw a card.’” Casting a spell for its blitz cost follows the rules for paying alternative costs in rules 601.2b and 601.2f–h.

If a spell has multiple instances of blitz, only one may be used to cast that spell. If a permanent has multiple instances of blitz, each one refers only to payments made for that blitz ability as the spell was cast, not to any payments made for other instances of blitz.
