Sharae of Numbing Depths

Stun counters gave white-blue a tempo lever it never quite had: a way to keep a creature tapped down that costs the opponent two untap steps instead of one. This card turns that lever into a draw engine. The enters-the-battlefield tap-and-stun buys an initial opening, but the standing ability is the interesting part, converting your own act of tapping an opponent's untapped creatures into a card, once per turn. The precise wording matters: the trigger fires only when you tap them, so an opponent tapping their own creatures to attack does nothing, and the engine runs on effects you point at the board rather than on combat happening to you. That once-per-turn clamp keeps it from spiraling: it rewards repeatable tappers over a single explosive turn, so a board full of Merfolk with tap abilities or a well-placed Icy Manipulator each feed exactly one draw before the meter resets. Icy Manipulator is the model here precisely because it never runs dry, a permanent that can point at a fresh untapped creature every turn and hand you a card each time. It is a 2/3 that would rather stall the ground and refill your hand than trade, a role-player for anyone treating tapped-down blockers as a resource loop rather than one-time disruption.
