Arm with Aether

The clever piece of structure is where the trigger sits: it keys off dealing damage to an opponent, not off combat itself, and it limits the bounce to creatures that player controls. That makes it a one-sided unsummoning whose payout scales with how many attackers connect. Land a swing with three unblocked bodies and you can return three of the defender's blockers or threats to hand, clearing the way for a follow-up the opponent has to rebuild against from scratch. The sorcery timing is the constraint that keeps it from being a true ambush trick: you commit to the effect before attackers are even declared, so the read on whether the blocks fall your way has to be made up front rather than in response. The damage requirement is the other limiter, since a chump-blocked attacker deals no damage to a player and triggers nothing, so the whole spell hinges on connecting. It belongs to a line of blue enchant-the-team combat effects that try to convert a creature deck's clock into board advantage, but the bounce here is firmly a tempo play rather than removal: everything you return is back in hand next turn, and the effect itself expires at end of turn. The ceiling is loud on a wide board built to overrun blockers; the floor is a do-nothing sorcery the moment your attack gets walled.
