Strix Serenade

Counterspells that give something back are an old idea: Dream Fracture drew a card back, Exclude found you a creature. The compensation clause here is more pointed than either. Countering an artifact, creature, or planeswalker spell for a single blue mana is a hard rate, and the price is that the opponent gets a 2/2 flier for their trouble. That token is not a throwaway. Against a control mirror or a durdling midrange deck it does almost nothing, but against an aggressive board it hands the beatdown player a real clock, and against a spot-removal-light deck it sticks around to chip in. The design is doing something subtle with the target restriction, too: it cannot touch instants or sorceries, so it is deliberately blind to the burn spell aimed at your face and the counterspell aimed at your play. This is permission built for the threat-dense end of the format, where the things worth countering are permanents and the tempo you buy by stopping a four-drop on turn one outweighs the two power you loan back. It is a tempo tool that punishes you for using it as a control tool, which is the whole tension: cheap enough to run in a deck that wants to be ahead, costly enough that the deck falling behind should not want it.
