La Comarca

The legendary creature must already be on the battlefield as the land enters the battlefield. If it enters the battlefield at the same time, the land will enter tapped.

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.

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

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