The Sibsig Ceremony + Myr Retriever + Scrap Trawler + Armor Wars

The Sibsig Ceremony

Myr Retriever

Scrap Trawler

Armor Wars

How it works

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

This clever loop feeds on itself by leveraging mana-reduction to cast free artifact creatures over and over again. The Sibsig Ceremony provides that crucial cost reduction while instantly sacrificing your newly cast creatures upon entry, feeding the graveyard to fuel continuous recursion. Whenever Myr Retriever bites the dust, its death trigger pulls Scrap Trawler back to your hand, and when Scrap Trawler meets the same fate, it reaches down to grab Myr Retriever right back. Meanwhile, Armor Wars can help draw you into the pieces or reduce costs further along the way, turning this endless cycle of sacrifice and recovery into an infinite stream of tokens and death triggers.
