The Sibsig Ceremony + Myr Retriever + Junk Diver + Ezzaroot Channeler

The Sibsig Ceremony

Myr Retriever

Junk Diver

Ezzaroot Channeler

How it works

1. Cast Junk Diver by paying 0.
2. When Junk Diver enters the battlefield, The Sibsig Ceremony triggers, destroying Junk Diver and creating a 2/2 Zombie Druid creature token.
3. When Junk Diver dies, it triggers, returning Myr Retriever from your graveyard to your hand.
4. Cast Myr Retriever by paying 0.
5. When Myr Retriever enters the battlefield, The Sibsig Ceremony triggers, destroying Myr Retriever and creating a 2/2 Zombie Druid creature token.
6. When Myr Retriever dies, it triggers, returning Junk Diver from your graveyard to your hand.
7. Repeat.

This clever recursion engine relies on the cost-reduction stacking of both The Sibsig Ceremony and Ezzaroot Channeler to reduce artifact creature spells to zero mana. You begin by tapping Ezzaroot Channeler for two life, making its discount large enough to cast Junk Diver and Myr Retriever for free. Once cast, The Sibsig Ceremony immediately destroys the incoming artifact creature, sending it to the graveyard and creating a 2/2 Zombie Druid token. This death triggers the sacrificed automaton—whether it is Junk Diver or Myr Retriever—to pull the other recursion piece right back out of your graveyard, allowing you to seamlessly loop the pair forever.
