Might of Oaks

Seven points of power and seven of toughness, dropped at instant speed onto any creature, is a number chosen to do exactly one job: turn a creature blocked or unblocked into a kill. The +7/+7 is not an incremental pump; it is a threshold designed to clear the math on almost any board. Block it and your blocker dies while the buffed attacker survives; leave it unblocked and the swing is usually lethal on its own. Green has a long tradition of these all-in combat numbers, the burst pumps that turn a single creature into a finisher rather than nudging a fight, and this sits at the top end of that family alongside effects like Berserk and the later Brute Force. What disciplines the card is its cost and its blink-and-it's-gone duration: four mana for a one-shot trick that does nothing if the creature is removed in response, and nothing at all to the board the turn after. The reward for paying full freight and holding it up is the surprise factor of an instant: an opponent who counts the combat math correctly still loses to the seven points they could not see, which is the entire reason the effect lives on an instant rather than a sorcery. It is a blowout printed as a single overwhelming number.
