• WOTC Official Reminder Textofficial rules
  Blitz — If you cast this spell for its blitz cost, it gains haste and "When this creature dies, draw a card." Sacrifice it at the beginning of the next end step.

  Menace — This creature can't be blocked except by two or more creatures.

  Official Ruling
  If you pay the blitz cost to cast a creature spell, that permanent will be sacrificed only if it's still on the battlefield when that triggered ability resolves. If it dies or goes to another zone before then, it will stay where it is.
• WWizards of the Coast2024-09-20
  Official Ruling
  If a creature enters as a copy of or becomes a copy of a creature whose blitz cost was paid, the copy won't have haste, won't be sacrificed, and its controller won't draw a card when it dies.
• WWizards of the Coast2024-09-20
  Official Ruling
  If you choose to pay the blitz cost rather than the mana cost, you're still casting the spell. It goes on the stack and can be responded to and countered. You can cast a creature spell for its blitz cost only if you could cast that creature spell. Most of the time, this means during your main phase when the stack is empty.
• WWizards of the Coast2024-09-20
  Official Ruling
  If the creature was cast using its blitz ability, the triggered ability that lets its controller draw a card triggers when it dies for any reason, not just when you sacrifice it during the end step.
• WWizards of the Coast2024-09-20
  Official Ruling
  If the target permanent is an illegal target as Star Athlete's second ability tries to resolve, it won't resolve and none of its effects will happen. No player will be dealt damage, and no permanents will be sacked . . . er, sacrificed.
• WWizards of the Coast2024-09-20
  Official Ruling
  You don't have to attack with the creature with blitz unless another ability says you do.
