Ranger's Guile

Protection that arrives at instant speed, folded into a combat trick small enough to leave one mana open all game. The hexproof is the load-bearing word: a single green mana spent in response neutralizes a targeted removal spell, a bounce, an aura, or an Act of Treason effect, and the +1/+1 means the same card doubles as a blocking surprise or a reach-the-finish-line pump when nobody is trying to kill the creature. That dual purpose is what keeps the slot earning its place. A pure protection spell can sit dead in hand for whole games; bolting a stat bump onto the back of it gives the card a floor, so the green deck holding it up is never wasting the slot. Then there is the bluff: with just one mana held open, an opponent eyeing a clean removal spell has to weigh whether that untapped green source means a one-mana answer they cannot afford to walk into, so the card does work even on turns it stays in hand. It does nothing proactive and cannot save a creature from a board wipe or an edict, the two things hexproof was never meant to cover, but as cheap insurance for the one creature a green deck has committed to, it occupies a slot the color keeps wanting filled.
