5 rulings from Wizards of the Coast
- 26 July 2024If you don't have enough cards in your graveyard or a Food on the battlefield, you can't choose to forage.
- 26 July 2024Once you announce that you're casting a spell or activating an ability, players can't take actions until you've finished doing so. Notably, opponents can't try to remove cards from your graveyard or Foods you control to stop you from foraging.
- 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 2024Food is an artifact type. Even though it appears on some creatures, it's never a creature type.
