Abandoned Sarcophagus + Infinite Reflection + Verdant Eidolon + Flourishing Fox

Abandoned Sarcophagus

Infinite Reflection

Verdant Eidolon

Flourishing Fox

How it works

1. Cast Flourishing Fox either from your hand or from your graveyard by paying , causing it to enter the battlefield as a copy of Verdant Eidolon due to Infinite Reflection.
2. Activate Flourishing Fox by paying and sacrificing it, adding or .
3. If you cast Flourishing Fox from your graveyard, Flourishing Fox is not exiled by Abandoned Sarcophagus due to Infinite Reflection removing Flourishing Fox's cycling ability.
4. Repeat.

This ingenious loop relies on Infinite Reflection to rewrite reality for your team, turning your Flourishing Fox into a copy of Verdant Eidolon the moment it enters the battlefield. Ordinarily, Abandoned Sarcophagus would exile any non-cycled card leaving the graveyard, but because Infinite Reflection strips away the original cycling text from the cloned Flourishing Fox, the Sarcophagus's restriction is safely bypassed. This allows you to repeatedly cast Flourishing Fox from your graveyard for its mana cost, sacrifice the creature to Verdant Eidolon's activated ability for a generous return of three mana, and loop it infinitely to generate boundless colored mana alongside limitless death and entry triggers.
