The Ring's Oppression is a largely worthless card that tries to tie together three concepts (killing companions, adding burdens, forcing the wearing of the ring) that don't generally have very much to do with one another. Although there are several Nazgul cards that work with mixing killing companions and adding burdens together (Drawn to Its Power, Dark Whispers, Nazgul Sword), these cards cannot be used effectively with The Ring's Oppression because it requires that a Orc be the one killing a companion, rather than spotting a Orc. Meanwhile other Nazgul cards that derive benefits from the Ringbearer wearing the ring, such as Wraith-World and The Twilight World, don't have the additional requirement of needing to kill a companion. On top of all of this The Ring's Oppression is expensive, and not really worth the play if it's only adding a single burden. This card has mild synergy with Orc Officer, but the three twilight spent on it would probably be better spent on a minion.
