Toph, the First Metalbender + Haru, Hidden Talent + Universal Automaton + Carrion Feeder

Toph, the First Metalbender

Haru, Hidden Talent

Universal Automaton

Carrion Feeder

How it works

1. Cast Universal Automaton by paying 1.
2. When Universal Automaton enters, Haru triggers, targeting Universal Automaton as it is a land due to Toph.
3. Activate Carrion Feeder by sacrificing Universal Automaton.
4. When Universal Automaton dies, Haru triggers, returning Universal Automaton from your graveyard to the battlefield tapped.
5. When Universal Automaton enters, Haru triggers, targeting Universal Automaton as it is a land due to Toph.
6. Resolve the Carrion Feeder ability.
7. Repeat from step 3.

This clever loop relies on Toph, the First Metalbender turning all your nontoken artifacts into lands, transforming Universal Automaton into both a creature and a land the moment it enters the battlefield. This dual type identity allows Haru, Hidden Talent to treat the entering Automaton as a land target for its earthbend trigger, while Carrion Feeder stands ready to sacrifice the Automaton whenever you need. Because the earthbend ability ensures that when the land-creature dies or is exiled it returns to the battlefield tapped, sacrificing the Automaton feeds right back into Haru's triggers to restart the entire cycle.
