Thought Collapse (JMP-184) is a common blue Instant from the Jumpstart set. It attempts to counter a target spell and causes that spell's controller to put the top three cards of their library into their graveyard. Because the milling effect still applies even if the spell can’t be countered, it serves both as countermagic and as pressure against graveyard-focused strategies.
