Old Flitterfang

2023-09-01 Food is an artifact type. Even though it appears on some creatures, it's never a creature type.
2023-09-01 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 to activate the last ability of Sweettooth Witch.
2023-09-01 Old Flitterfang's triggered ability will check as the end step starts to see if a creature died this turn. If none did, the ability won't trigger at all.
2023-09-01 Some spells and abilities that create Food tokens may require targets. If each target chosen is an illegal target as that spell or ability tries to resolve, it won't resolve. You won't create any Food tokens.
2023-09-01 Whatever you do, don't eat the delicious cards.
2023-09-01 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 the last ability of Sweettooth Witch.
