原文If the target creature can't block for any reason (such as being tapped), then it doesn't block. If there's a cost associated with having it block, its controller isn't forced to pay that cost, so it doesn't have to block in that case either.
原文If an effect refers to a Food, it means any Food artifact, not just a Food artifact token. For example, you can sacrifice Gingerbrute to activate the last ability of Tempting Witch.
