Krosan Grip

The extra mana never buys the destruction effect: green has always had cheaper ways to break a Disenchant target. It buys the guarantee. Naturalize and its kin can be answered, and a sacrifice outlet, a flash-in protection spell, or a fizzle in response can turn the removal into a wasted card at the worst possible moment. Split second closes every one of those windows. Once this is on the stack nobody gets to cast a spell or activate a non-mana ability in response, so the artifact or enchantment is destroyed before its controller can do anything about it. That makes it the card you reach for not when you need cheap interaction but when you cannot afford to be answered: the combo piece that doubles as its own protection, the indestructible-granting enchantment, the linchpin permanent whose controller has held up exactly the spell that would save it. The cost line is deliberately a tax on certainty, the price of removing the back-and-forth that defines most interaction. It is also one of the cleanest demonstrations of what split second was built to sell: not value, not efficiency, but unconditionality. In a game built around the stack and the responses it enables, this strips that conversation down to a single, unanswerable sentence.
