Garnet, Princess of Alexandria

Sagas were designed to spend themselves: each added lore counter marches the chapter forward until the enchantment sacrifices itself, and the whole clock is one-directional by construction. This is the payoff for interrupting that clock. Instead of letting a Saga read its final chapter and leave, the attack trigger cashes a lore counter from each into permanent stat growth, converting an enchantment's countdown into a creature's size. That is the wrinkle worth dwelling on: the trigger fires on attack, so the +1/+1 counters land before combat damage, and each Saga you drain pauses one chapter closer to keeping it on the battlefield. A Saga that would soon complete and die instead lingers longer, and the attacker swings bigger for it. The design asks a genuinely unusual question of a green-white board: whether you would rather a Saga finish its story or feed the princess. Lifelink is the quiet multiplier here, since every counter added widens the life swing on the same attack that grew the body. Two-mana legendary bodies that scale are common enough; one that scales by rationing the resource an entire archetype was built to burn through is a sharper piece of tension, and it makes Sagas worth running for a reason other than their final chapters.
