Vexing Shusher

A hatebear with one job, and it does that job from both directions. The body itself can't be countered, so it lands no matter how much blue mana sits across the table; the activated ability then extends that protection to any spell on the stack, yours or your opponent's, for a single hybrid pip. That second clause is the cleverer half: a player can activate it in response to a Counterspell, and because the ability resolves before the counter does, the targeted spell becomes uncounterable while the would-be answer is still waiting underneath it on the stack. Paying every symbol with either red or green keeps the design unusually reachable: a deck touching just one of its two colors fields it without a fixing tax, and the activation never strands you on the wrong source. As a structural answer it is narrower than removal and broader than a single named card, because it does not care what the counterspell is, only that one exists. The effect targets the spell rather than the caster, so it protects a combo piece, a planeswalker, or its own follow-up turn with equal ease. Goblin Shaman is the flavor wrapper on a piece of pure anti-control engineering: a creature whose entire reason to exist is to make "no" stop being an answer.
