Immortal Obligation

Reanimation from an opponent's graveyard has historically been black's specialty, sometimes blue's through outright theft; white shows up here with a very different bargain. The terms of the deal are the design. Instead of stealing the creature for yourself or bringing it back on your side, this hands the body back to its owner and then legally muzzles it against you: the duty counter goads the returned creature while forbidding it from ever swinging at you, blocking your creatures, or menacing your permanents. You are resurrecting an opponent's threat and aiming it at the rest of the table. That reframes reanimation as a political instrument rather than a value engine, which is exactly the kind of effect white's multiplayer identity has been circling for years. The counter is what makes the arrangement stick: as long as it stays on the creature, the compulsion holds, tying the effect to the multiplayer math of goad (a creature that must attack but can never attack you is a directed weapon pointed at whoever is left). It also addresses a recurring gap in white's graveyard interaction, which has always been better at exiling opposing yards than exploiting them; rather than denying the resource, this borrows it and turns its owner's own dead into a liability. At instant speed, you can drop the returned creature into an opponent's turn, saddling them with a body that answers to your terms at a moment they cannot plan around.
