Sauron, the Necromancer

The Ring-bearer clause is where the whole design lives. Every attack pulls a creature out of your graveyard and copies it as a tapped, attacking 3/3 Wraith with menace, but that copy is exiled at the next end step unless this creature is your Ring-bearer. Two entirely different cards live inside that conditional. Ungirded, it is a recurring hasty-attacker generator: reanimation-as-a-loan, where the payoff is whatever enter-the-battlefield trigger the copied card carries, plus a body swinging for one turn before it leaves. The token arrives already tapped and attacking, so it never triggers an "whenever this creature attacks" ability of its own; the front-loaded value is the ETB and the combat step, nothing more. Because the token is exiled rather than destroyed, it never returns to the graveyard and never fires a death trigger, which keeps the loop from folding back on itself. Once this creature becomes your Ring-bearer (and the Ring's escalating protections make that harder to interrupt with each temptation), the exile clause stops applying and the loaned Wraiths stay. The mechanic turns Ring-tempting from flavor dressing into the load-bearing incentive: carry the Ring and your recursion stops being temporary and starts compounding. The 3/3 rewrite is what pays for all of this. Copy any creature and you get a 3/3 black Wraith, not the original stat line, so what you buy back is the textbox rather than the body. That steers the card toward high-impact triggers over large beaters and keeps it from becoming a plain reanimator returning the exact creature it took.
