Sewers of Estark (PHPR-2) is a rare instant from the HarperPrism Book Promos set. It targets a creature and, on resolution, gives that creature either unblockable if it's attacking or prevents all combat damage it would deal and receive if it's blocking. The spell can target any creature but only has an effect if the target is attacking or blocking when the spell resolves.
