Magic Damper

Bundle four small verbs into one blue instant and you get a combat trick that does most of its work on defense. The +1/+1 is almost the least of it: hexproof for a turn slips the creature out from under a spot-removal spell or a targeted trigger during a moment when it would otherwise die, and the untap turns a tapped-out attacker into a surprise blocker or clears the way for a tap-activated ability to fire twice in a turn. The combination rewards initiative in the same way older protection tricks did, but it splits the payoff across three axes that rarely appear together at one mana: a small stat bump, a removal dodge, and a reset of the creature's tapped state. That untap clause is the wrinkle that separates it from a plain protection spell; it lets a single creature attack and then hold the fort, or squeeze an extra activation out of a mana dork or a tapper before the turn cycles. None of the pieces is individually remarkable, but stacking them on one target at instant speed asks the caster to read the board and pick the moment: the trick is only as good as the creature you point it at and the window you choose to fire it in.
