Cauldron Familiar
Creature — Cat
When this creature enters, each opponent loses 1 life and you gain 1 life.
Sacrifice a Food: Return this card from your graveyard to the battlefield.
Every day the cat returns to kill the same mouse, which sinks again into the cauldron's brew.

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 (an Artifact Creature — Food Golem) to activate Maraleaf Rider's ability (an ability with "Sacrifice a Food" in its cost).

In a Two-Headed Giant game, Cauldron Familiar's first ability causes the opposing team to lose 1 life twice, and you gain 1 life once.

You can't activate Cauldron Familiar's last ability unless it's in your graveyard.
