Djeru's Resolve

The combat trick that doubles as a non-card. Untapping a creature and fogging the damage headed its way is a defensive sleight of hand: it lets a tapped-out blocker enter combat unexpectedly, or keeps a creature alive through a swing it could not normally survive. Because the prevention is broad (all damage to that creature this turn, from any source), it also blanks a burn spell or a damage-based finisher pointed at one target; what it cannot touch is the destroy-or-exile half of removal, since nothing here changes the creature's fate once a spell resolves around its toughness. None of that is what earns the card its slot, though. What justifies running a spell this narrow is the discard-for-a-card back half: when there is no profitable combat to engineer and no creature worth saving, the trick sheds itself for a modest cost, so a draw of it never bricks the hand. That dual-mode construction (a situational instant on top, a cantrip underneath) is what lets narrow protection spells be tuned aggressively, because the downside is capped by the escape hatch. The untap-and-fog effect belongs to a familiar family of one-mana white protection spells, but the ability to cash the card in is the wrinkle that decides whether the front of the card ever matters.
