Taste of Death

Each player sacrifices three creatures. You create three Food tokens. (They're artifacts with "{2}, {T}, Sacrifice this artifact: You gain 3 life.")

As Taste of Death resolves, first the player whose turn it is chooses three creatures they control, then each other player in turn order does the same, knowing the choices made before them. Then all the chosen creatures are sacrificed at the same time.

Food is an artifact type. Even though it appears on some creatures (such as Gingerbrute), it's never a creature type.

If a player controls three or fewer creatures, that player sacrifices each creature they control.

Whatever you do, don't eat the delicious cards.

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 ability of Tempting Witch.

You create three Food tokens, no matter how many creatures were actually sacrificed, even if some or all players sacrificed no creatures.
