Mortuary + Blasting Station + Bolas's Citadel + Haywire Mite

Mortuary

Blasting Station

Bolas's Citadel

Haywire Mite

How it works

1. Activate Blasting Station by tapping it and sacrificing Haywire Mite.
2. When Haywire Mite dies, it and Mortuary triggers.
3. Resolve the Mortuary trigger, putting Haywire Mite from your graveyard onto the top of your library.
4. Resolve the Haywire Mite trigger, causing you to gain 2 life
5. Resolve the Blasting Station ability.
6. Cast Haywire Mite from the top of your library by paying 1 life due to Bolas's Citadel.
7. When Haywire Mite enters, Blasting Station triggers, untapping Haywire Mite.
8. Repeat.

This loop transforms a humble artifact bug into a perpetual engine of destruction by turning death into recursion. You start by sacrificing Haywire Mite to Blasting Station, which triggers its own life-gain ability while Mortuary immediately scoops the Mite right out of your graveyard and places it back onto the top of your library. From there, Bolas's Citadel steps in to bypass normal mana constraints entirely, letting you replay the Mite from the top of your library by paying a single point of life. Every time the Mite re-enters, Blasting Station untaps itself so you can repeat the process, slowly grinding your opponents down with infinite damage while netting positive life along the way.
