Dawn Charm

Three white instants that already existed in isolation, stapled onto a single mode selection: a Fog, a regeneration shield, and a counter narrowed to spells aimed at you. Each mode is individually playable but unremarkable; the trick is that you commit two mana without committing to a problem, then answer whichever one shows up. The alpha strike you didn't see coming gets fogged. The removal aimed at your blocker gets eaten by the regenerate. The burn spell or edict pointed at your face gets countered outright. That last mode is the most interesting structurally, because it functions as a narrowed relative of the spells that protect a player from being targeted: it does nothing against a sweeper or a creature kill spell, but against the specific class of "you, the player, are the target" effects it is a clean Negate that the opponent cannot play around by sequencing. The trade for that flexibility is that no single mode is the best version of itself, and you only ever pick one per cast. It is a card built for the deck that wants to leave white mana up and refuse to telegraph what the answer is, then choose the answer on the stack once the threat declares itself.
