Spell Snuff
Counterspell set the price for a hard answer at two mana with a double-blue commitment, and the design ledger has been trying to justify the extra generic ever since. This one pays for that added mana with fateful hour, a rider that only fires when you have five or less life: at that point the counter also cantrips. That is the honest tension in the card. The reward arrives precisely when it matters least. By the time your life total has cratered to the threshold, drawing one card off a counter is rarely the margin between living and dying; the counter itself was always the load-bearing half of the transaction, doing the same clean work whether the bonus fires or not. Fateful hour was a keyword built to reward decks scrapping to survive at the razor's edge, but a control shell paying three for a hard counter is usually the deck engineering its whole game plan to keep its life total nowhere near five. So the flavor and the mechanics point at a heroic last stand while the actual job is the unconditional answer any three-mana counter provides. The bonus is genuine; it just describes a board state you spent the entire match trying to avoid ever reaching.
