Molten Echoes + Unstoppable Ash

Molten Echoes

Unstoppable Ash

How it works

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

By naming Treefolk or Warrior as it enters, Molten Echoes sets up a marvelous loop every time a matching creature arrives. When you cast Unstoppable Ash, its champion ability and the enchantment's copy effect trigger simultaneously, allowing the token copy to champion the original. That transient token then leaves the battlefield to exile itself, which instantly gives back the original Unstoppable Ash and lets you repeat the entire sequence for infinite entry and departure triggers.
