Giant Opportunity

2019-10-04 Food is an artifact type. Even though it appears on some creatures (such as Gingerbrute), it's never a creature type.
2019-10-04 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.
2019-10-04 Whatever you do, don't eat the delicious cards.
2019-10-04 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.
2019-10-04 You can't sacrifice more than two Foods to create more than one Giant token.
2019-10-04 You choose whether to sacrifice two Foods as Giant Opportunity resolves, not as you cast it.
