Abandoned Sarcophagus + Infinite Reflection + Rith's Attendant + Hollow One

Abandoned Sarcophagus

Infinite Reflection

Rith's Attendant

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 Rith's Attendant due to Infinite Reflection.
2. Activate Hollow One by paying 1 and 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 fascinating loop turns Hollow One into an endless mana-producing engine by leveraging the copy effects of Infinite Reflection. Because Infinite Reflection strips away the original text of your nontoken creatures, a Hollow One entering the battlefield adopts Rith's Attendant's characteristics—including its mana-producing sacrifice ability—while cleverly shedding its own cycling ability. This exemption is crucial when combined with Abandoned Sarcophagus, as the lack of a cycling ability prevents the Sarcophagus from exiling Hollow One when it hits the graveyard, allowing you to recast it for next to nothing and repeat the sacrifice indefinitely.
