Kami of Jealous Thirst

A drain ability priced at five mana is a rounding error; the card is built so you almost never pay full freight. The cost reduction keys off drawing three cards in a turn, and once that threshold is met the activation shrinks all the way to , a free two-point drain every turn. That conditional is the whole design: a payoff stapled to a deathtouch body, aimed at the kind of deck that treats a hand full of cantrips as its baseline rather than a spike. The 1/3 with deathtouch is not incidental either. It survives most early attackers, deters combat while you assemble the card-draw engine, and turns any block or trade into a threat. Where Sanguine Bond and Vito, Thorn of the Dusk Rose ask you to build around a life-loss trigger, this asks only that you were going to draw a lot of cards anyway, then rewards the surplus with an inevitability clock. The once-per-turn cap keeps it honest against storm-style burst turns: the drain accrues one activation at a time rather than emptying an opponent in a single explosive sequence. It is a slow-drip win condition for a spellslinger shell, the reward the deck earns for doing what it already wanted to do.
