{T}: Until end of turn, you may cast creature spells from your graveyard by foraging in addition to paying their other costs. If you cast a spell this way, that creature enters with a finality counter on it. (To forage, exile three cards from your graveyard or sacrifice a Food. If a creature with a finality counter on it would die, exile it instead.)

11 rulings from Wizards of the Coast
- 26 July 2024You must still follow timing restrictions and permissions for creature spells you cast with the permission granted by Osteomancer Adept's last ability. Normally, you'll be able to cast them only during your main phase while the stack is empty.
- 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 2024Multiple finality counters on a single permanent are redundant.
- 26 July 2024Finality counters aren't keyword counters, and a finality counter doesn't give any abilities to the permanent it's on. If that permanent loses its abilities and then would go to a graveyard, it will still be exiled instead.
- 26 July 2024If Dryad Arbor (the only card that's both a creature and a land) is in your graveyard, you can't play it this way. Dryad Arbor can't be cast as a spell.
- 26 July 2024Finality counters work on any permanent, not only creatures. If a permanent with a finality counter on it would be put into a graveyard from the battlefield, exile it instead.
- 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.
- 26 July 2024Finality counters don't stop permanents from going to zones other than the graveyard from the battlefield. For example, if a permanent with a finality counter on it would be put into its owner's hand from the battlefield, it does so normally.
- 8 November 2024Food is an artifact type. Even though it appears on some creatures, it's never a creature type.
- 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 2024Whatever you do, don't eat the delicious cards.
