Deathrender + Myr Retriever + Scrap Trawler + Blasting Station

Deathrender

Myr Retriever

Scrap Trawler

Blasting Station

How it works

1. Activate Blasting Station by tapping it and sacrificing Myr Retriever.
2. Myr Retriever dies, triggering itself and Deathrender.
3. Resolve the Myr Retriever trigger, returning Scrap Trawler from your graveyard to your hand.
4. Resolve the Deathrender trigger, putting Scrap Trawler from your hand onto the battlefield, and attaching Deathrender to it.
5. Scrap Trawler enters the battlefield, triggering Blasting Station, untapping Blasting Station.
6. Resolve the Blasting Station ability from step 1, dealing 1 damage to any target.
7. Activate Blasting Station by tapping it and sacrificing Scrap Trawler.
8. Scrap Trawler dies, triggering itself and Deathrender.
9. Resolve the Scrap Trawler trigger, returning Myr Retriever from your graveyard to your hand.
10. Resolve the Deathrender trigger, putting Myr Retriever from your hand onto the battlefield, and attaching Deathrender to it.
11. Myr Retriever enters the battlefield, triggering Blasting Station, untapping Blasting Station.
12. Resolve the Blasting Station ability from step 7, dealing 1 damage to any target.
13. Repeat.

This loop creates a deadly feedback loop by continuously bouncing artifacts between the graveyard and hand, fueled by the recursive triggers of Myr Retriever and Scrap Trawler. As each creature falls to Blasting Station's sacrifice outlet, Deathrender immediately cheats the next one from your hand straight onto the battlefield equipped and ready to go. Because Scrap Trawler's ability continuously salvages whatever artifact just hit the bin with a lesser mana value, the loop feeds itself indefinitely while Blasting Station untaps on every entry to rain down infinite damage upon any target.
