Molten Echoes + Thoughtweft Trio

Molten Echoes

Thoughtweft Trio

How it works

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

This clever loop revolves around setting Molten Echoes to the Kithkin creature type so that every arrival triggers an endless cascade of copies. When you cast Thoughtweft Trio, its entry triggers both the enchantment and its own champion ability, allowing the resulting token copy to champion the original. As the token leaves the battlefield to exile the nontoken version, it immediately sends the original Thoughtweft Trio crashing back onto the battlefield, creating a self-sustaining cycle of endless enters-the-battlefield and leaves-the-battlefield triggers.
