Remembrance + Mortuary + Blasting Station + Ornithopter

Remembrance

Mortuary

Blasting Station

Ornithopter

How it works

1. Activate Blasting Station by tapping it and sacrificing Ornithopter.
2. When Ornithopter dies, Mortuary and Remembrance trigger.
3. Resolve the Mortuary trigger, putting Ornithopter from your graveyard on top of your library.
4. Resolve the Remembrance trigger, searching your library for Ornithopter and putting it into your hand.
5. Resolve the Blasting Station ability, dealing 1 damage to any target.
6. Cast Ornithopter by paying 0.
7. When Ornithopter enters the battlefield, Blasting Station triggers, untapping Blasting Station.
8. Repeat.

This clever loop turns the free-casting nature of Ornithopter into a lethal engine of destruction by turning a single death into a perpetual recursion cycle. When you sacrifice the zero-mana flyer to Blasting Station, Mortuary steps in to place Ornithopter right back on top of your library while Remembrance simultaneously tutors a duplicate straight to your hand. Because Ornithopter costs nothing to recast, casting it immediately triggers Blasting Station's untap ability, resetting the artifact so you can repeat the process and deal infinite damage to any target.
