Sovereign's Bite

A six-point life swing for two mana, which is the cleanest way to state what this is and also the reason it has never mattered much. Life drain is one of the effects black has printed in every era, but the rate here is the trap: three life lost, three life gained, no body left behind, no graveyard interaction, no flexibility on whether the target loses life or just you gain it. Compare the cards that built the drain lineage and earned their slots: Gray Merchant of Asphodel scales with devotion and sticks a creature, Vampire Nighthawk drains through combat over multiple turns, even a humble Sign in Blood at the same cost trades the life swing for cards, which a deck almost always wants more. Sovereign's Bite spends a card and a turn to move six total life points with nothing attached. That is fine math in a vacuum and poor math against opportunity cost, since the formats where six life matters most are also the ones where a do-nothing sorcery is least affordable. It exists as common-rarity reprintable filler for a life-drain theme: the kind of effect a beginner reaches for because the swing reads big, and a tuned deck leaves in the binder because the swing does not advance the board.
