Mortuary + Blasting Station + Crimson Kobolds + Gwenom, Remorseless

Mortuary

Blasting Station

Crimson Kobolds

Gwenom, Remorseless

How it works

1. Activate Blasting Station by tapping it and sacrificing Crimson Kobolds
2. When Crimson Kobolds dies, Mortuary triggers, putting Crimson Kobolds from your graveyard onto the top of your library.
3. Resolve the Blasting Station ability.
4. Cast Crimson Kobolds from the top of your library by paying 0 life.
5. When Crimson Kobolds enters, Blasting Station triggers, untapping Blasting Station.
6. Repeat.

This ingenious loop turns a zero-mana creature into a relentless engine of destruction by leveraging Gwenom, Remorseless to completely bypass mana costs from the top of your library. When you sacrifice Crimson Kobolds to Blasting Station, Mortuary instantly intercepts the creature on its way to the graveyard and stacks it right back on top of your library for re-casting. Meanwhile, Blasting Station's own untap trigger resets the artifact every time Crimson Kobolds re-enters the battlefield, letting you repeat the cycle indefinitely to machine-gun down any target with endless damage.
