Haunting Hymn

The hidden lever here is the timing clause, and it cuts against the grain of how black discard usually works. Most targeted hand attack rewards you for acting on the opponent's turn or in response to something: instant-speed flexibility is the selling point. This one inverts that, paying you double for casting it the slow way, during your own main phase, when you have no idea what the opponent just drew and no reaction to punish. Cast reactively it strips two; cast proactively it strips four, a near-emptying of a hand in the midgame. The design wants a tempo plan over a held-up response, and the six mana means that by the time you can fire it on your main phase with intent, the opponent has likely spent down to a few cards anyway. That is the tension the card is built around: the bigger effect demands the worse window. As a piece of discard it sits in the heavy, top-end tradition of mass hand disruption rather than the surgical one-mana strikes that define the archetype, closer in spirit to symmetrical wipes like Mind Twist than to a precise Thoughtseize. The reward is real (four cards is a wrecking ball) but it is gated behind sorcery-speed discipline on an instant's frame, an unusual ask that has kept the card well outside the disruption mainstream.
