Mystic Genesis (GTC)

Instant

Counter target spell. Create an X/X green Ooze creature token, where X is that spell's mana value.

Reliable counterspell with upside for blue-green control and tempo decks. Mystic Genesis punishes opponents for casting expensive threats by neutralizing them while leaving behind a proportional blocker or attacker. The token scales with what you're stopping—shutting down a five-mana threat nets you a 5/5—making it efficient removal in the mid-to-late game. Solid in Commander, Pioneer, and Modern control shells where you're already running interaction and want added value from your answers.
