Abandoned Sarcophagus + Infinite Reflection + Morgue Toad + Sandbar Merfolk

Abandoned Sarcophagus

Infinite Reflection

Morgue Toad

Sandbar Merfolk

How it works

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

This ingenious loop centers around Infinite Reflection, which transforms your entire team into a copy of whatever creature it enchants. When you target Morgue Toad with the Aura, every nontoken creature you control—including Sandbar Merfolk entering the battlefield—becomes an exact copy of the Toad with its mana-producing sacrifice ability intact. Crucially, because Infinite Reflection overwrites Sandbar Merfolk's text box as it enters, the card loses its printed cycling ability entirely. This circumvents the exile replacement effect on Abandoned Sarcophagus, allowing you to repeatedly cast Sandbar Merfolk straight from your graveyard using the red mana generated by sacrificing the creature it just became.
