Harm's Way
Most white damage prevention erases the hit and stops there: Healing Salve soaks it up, Holy Day blanks a combat step. This one refuses to let the damage vanish. Instead of cancelling two damage, it redirects it, peeling a chunk off whatever a chosen source would deal to you or your permanents and steering it wherever you like. The redirect pays off on both halves of the turn. On defense, an attacker's swing lands two lighter on you, and that two gets aimed back at the attacker, often killing the creature that threw the punch. On the stack, it answers an opponent's burn or damage-based removal pointed at your creature: the spell still resolves and still targets your creature, but the damage it would deal is reassigned, sparing your permanent and dropping two somewhere else, a small blocker, a planeswalker, the opponent's face. The card lives at the seam between protection and removal, a defensive spell that happens to deal damage, which is rare territory for the color. The cap of two is what keeps it from sliding into pure burn: enough to kill the small things that actually attack and block, never enough to function as a reliable finisher. It rewards reading the source-and-amount structure precisely, since the redirect names a source rather than a spell and counts damage rather than effects, which is what lets it answer threats that ordinary prevention would simply blunt rather than turn back.
