Tainted Treats

Food is an artifact type. Even though it appears on some creatures, it's never a creature type.

If an effect refers to a Food, it means any Food artifact, not just a Food artifact token. For example, you can sacrifice Pizza Face (a Legendary Artifact Creature — Food Mutant) to activate Maraleaf Rider's ability (an ability with "Sacrifice a Food" in its cost). 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.

Use the mana cost of the artifact or creature as it last existed on the battlefield to determine whether its mana value is 4 or less. If it had X generic mana in its cost, X is 0 for the purpose of determining its mana value.
