Molten Echoes + Wren's Run Packmaster

Molten Echoes

Wren's Run Packmaster

How it works

1. Cast Wren's Run Packmaster by paying its mana cost.
2. When Wren's Run Packmaster enters the battlefield, its champion ability and Molten Echoes triggers.
3. Resolve the Molten Echoes trigger, creating a token copy of Wren's Run Packmaster with haste.
4. When the Wren's Run Packmaster token enters the battlefiled, its champion ability triggers, exiling the nontoken Wren's Run Packmaster until the token Wren's Run Packmaster leaves the battlefield.
5. Resolve the champion ability from step 2, exiling the token Wren's Run Packmaster.
6. The token Wren's Run Packmaster leaves the battlefield, returning the nontoken Wren's Run Packmaster from exile to the battlefield.
7. Repeat from step 2.

This clever loop centers on the recursive interaction between Wren's Run Packmaster and Molten Echoes, turning a simple creature drop into an endless cycle of arrivals and departures. When you cast Wren's Run Packmaster and choose Elf for Molten Echoes, the resulting copy triggers its own champion ability to exile the original, which immediately returns the original once the token vanishes. Because Molten Echoes keeps triggering every time a new copy appears, this creates an infinite loop of leaves-the-battlefield and enters-the-battlefield events without ever needing to recast your commander.
