When Stonework Puma enters, Haru triggers, targeting Stonework Puma as it is a land due to Toph.
Activate Zuran Orb by sacrificing Stonework Puma.
When Stonework Puma dies, Haru triggers, returning Stonework Puma from your graveyard to the battlefield tapped.
When Stonework Puma enters, Haru triggers, targeting Stonework Puma as it is a land due to Toph.
Resolve the Zuran Orb ability.
Repeat from step 3.
Toph, the First Metalbender completely redefines the battlefield by turning all of your nontoken artifacts into lands, transforming support pieces into versatile targets. With that foundation in place, Haru, Hidden Talent acts as your engine, triggering its earthbend ability whenever another Ally enters the battlefield. Stonework Puma cleverly bridges these systems as an Ally that also counts as an artifact land, allowing it to repeatedly trigger Haru when it returns from the graveyard. Finally, Zuran Orb provides the sacrifice outlet needed to send Stonework Puma away, completing a seamless loop that generates endless life and triggers.
