Consecrate // Consume

Each split card has two names. If an effect instructs you to choose a card name, you may choose one of those names, but not both.

If an effect allows you to cast a spell with certain characteristics, consider only the characteristics of the half you're casting. For example, if an effect allows you to cast a sorcery spell with mana value 2 or less from among cards in your graveyard, you could cast Assault this way, but not Battery.

If you copy a spell that's half of a split card, the copy copies that same half. For example, if you copy Assault, the copy is also Assault, not Battery.

If the creature's power is negative, you don't lose or gain life.

The amount of life gained while Consume resolves is equal to the power of the creature as it last existed on the battlefield.

If the target player controls more than one creature with the greatest power among creatures they control, that player chooses which to sacrifice.
