  Food — , , Sacrifice this artifact: You gain 3 life.

• WWizards of the Coast2023-06-16
  Official Ruling
  Some abilities trigger "whenever you cast a historic spell." Such an ability resolves before the spell that caused it to trigger. It resolves even if that spell is countered.
• WWizards of the Coast2023-06-16
  Official Ruling
  Lands are never cast, so abilities that trigger "whenever you cast a historic spell" won't trigger if you play a legendary land. They also won't trigger if a card on the battlefield transforms into a card with the legendary supertype, the artifact card type, or the Saga subtype.
• WWizards of the Coast2023-06-16
  Official Ruling
  A card, spell, or permanent is historic if it has the legendary supertype, the artifact card type, or the Saga subtype. Having two of those qualities doesn't make an object more historic than another or provide an additional bonus—an object either is historic or it isn't.
• WWizards of the Coast2023-06-16
  Official Ruling
  An ability that triggers "whenever you cast a historic spell" doesn't trigger if a historic card is put onto the battlefield without being cast.
• WWizards of the Coast2024-11-08
  Official Ruling
  You can't sacrifice a Food to pay multiple costs. For example, you can't sacrifice a Food token to activate its own ability and also to activate Maraleaf Rider's ability.
• WWizards of the Coast2024-11-08
  Official Ruling
  Food is an artifact type. Even though it appears on some creatures, it's never a creature type.
• WWizards of the Coast2024-11-08
  Official Ruling
  If an effect refers to a Food, it means any Food artifact, not just a Food artifact token. For example, you can sacrifice Tough Cookie (an Artifact Creature — Food Golem) to activate Maraleaf Rider's ability (an ability with "Sacrifice a Food" in its cost).

  Official Ruling
  Whatever you do, don't eat the delicious cards.
