• WOTC Official Reminder Textofficial rules
  Ward — Whenever this permanent becomes the target of a spell or ability an opponent controls, counter it unless that player pays [cost].

• WWizards of the Coast2024-07-26
  Official Ruling
  The affected creatures retain their other types and abilities.
• WWizards of the Coast2024-07-26
  Official Ruling
  Creatures that die while you control Ygra are still Food artifacts as they leave the battlefield, so Ygra's last ability will trigger whenever a creature affected by its second ability dies.
• WWizards of the Coast2024-07-26
  Official Ruling
  Replacement effects that modify artifacts as they enter will apply after you apply Ygra's effect. For example, if you control Ygra and there is an effect that says artifacts enter tapped, creatures will enter tapped.

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