Abandoned Sarcophagus + Infinite Reflection + Morgue Toad + Hollow One

Abandoned Sarcophagus

Infinite Reflection

Morgue Toad

Hollow One

How it works

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

This clever loop transforms a humble creature into an engine for infinite mana by layering clone mechanics with graveyard recurrence. When you enchant Morgue Toad with Infinite Reflection, it permanently overwrites the characteristics of every other nontoken creature you control—including Hollow One—turning them all into exact copies of the Toad with its mana-producing sacrifice ability. Because Abandoned Sarcophagus normally exiles non-cycled cards with cycling when they hit the graveyard, the trick here is that Hollow One loses its printed cycling ability while on the battlefield as a copy of the Toad; this clever loophole ensures the creature can be recast repeatedly from your graveyard to fuel the loop infinitely.
