Fazendeiro da Quarta Leste

You don't choose a target for Eastfarthing Farmer's ability at the time it triggers. Rather, a second "reflexive" ability triggers when you create a Food token this way. You choose a target for that ability as it goes on the stack. Each player may respond to this triggered ability as normal.

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

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

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.
