This intricate loop turns a humble creature into a self-sustaining mana engine by leveraging how copy effects interact with alternate casting permissions and replacement effects. Once Infinite Reflection is attached to Treva's Attendant, every other nontoken creature you control—including any Flourishing Fox you cast—enters the battlefield as a copy of the Attendant, stripping away its original text box and cycling ability in the process. Because Abandoned Sarcophagus lets you repeatedly cast spells with cycling from your graveyard, and the copied creature's lack of a cycling ability prevents the Sarcophagus's exile replacement effect from triggering, you can recast the sacrificed Fox endlessly. Meanwhile, while the Fox's own text might be overwritten on the battlefield, the presence of cards like Flourishing Fox in the overall setup anchors the mechanical identity of the pieces that make this magical machinery hum.
