4 rulings from Wizards of the Coast
- 8 November 2024Whatever you do, don't eat the delicious cards.
- 8 November 2024You 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.
- 8 November 2024If 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).
- 8 November 2024Food is an artifact type. Even though it appears on some creatures, it's never a creature type.
