This elegant loop revolves around Twilight Shepherd and its built-in persist ability, which normally would exhaust itself after a single recursion due to the -1/-1 counter it accumulates. By anchoring the battlefield with Vizier of Remedies, that drawback is completely neutralized—its replacement effect ensures the Shepherd returns totally clean of counters every single time it dies. To drive the engine, Bartolomé del Presidio acts as the ultimate sacrifice outlet, continuously growing larger with +1/+1 counters while feeding the graveyard to fuel an endless stream of entries, leaves, and tragic demises.
