Meriadoc Brandybuck

Whenever one or more Halflings you control attack a player, create a Food token. (It's an artifact with "{2}, {T}, Sacrifice this artifact: You gain 3 life.")

Whenever one or more Halflings you control attack a player, create a Food token.

Do not eat the delicious cards. No, not even for second breakfast.

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

Halflings attacking a planeswalker or battle won't cause Meriadoc Brandybuck's ability to trigger.

If an effect refers to a Food, it means any Food artifact, not just a Food artifact token. For example, you can sacrifice Lembas, an artifact card with the Food subtype, to activate the last ability of Bill the Pony.

Meriadoc Brandybuck's ability has you create just one Food token per player you attack with a Halfling, no matter how many Halflings you attack them with beyond the first.

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.

You can't sacrifice a Food token 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 Bill the Pony.
