Restore the Peace

The reset button that only fires after combat is committed. A symmetrical bounce keyed to creatures that have dealt damage is a strange beast: it does nothing during the declare-attackers window, nothing to a board sitting back on defense, and everything to two armies that have just swung into each other. Cast it after blocks and damage, and every creature that connected (yours and theirs alike) goes back to its owner's hand, undoing the tempo of the entire combat while leaving untapped blockers and creatures that sat out the turn right where they were. The damage-this-turn condition is the whole pivot: it punishes the player who provoked the swing more than the one who held back, because returning a creature to hand demands the mana be spent again, and the attacker who committed more bodies and more mana to the assault has more to recast. It is closer in spirit to a Fog that also unwinds the board than to a clean wrath, since surviving creatures return to their owners' hands rather than being lost, but whoever overextended eats the larger tempo bill. The blue-white pairing is the natural home for this kind of trick: a tempo or control plan that wants to absorb an alpha strike, hand the aggressor a fistful of recast costs, and reset to a position where its own answers line up better. Instant-speed answers that hinge on a turn-defining combat have always been niche, but the timing puzzle here is real and specific.
