Mortuary + Woe Strider + Tarpan + Gwenom, Remorseless

Mortuary

Woe Strider

Tarpan

Gwenom, Remorseless

How it works

1. Activate Woe Strider by sacrificing Tarpan.
2. When Tarpan dies, it and Mortuary triggers.
3. Resolve the Mortuary trigger, putting Tarpan from your graveyard onto the top of your library.
4. Resolve the Tarpan trigger, causing you to gain 1 life
5. Resolve the Woe Strider ability.
6. Cast Tarpan from the top of your library by paying 1 life due to Gwenom.
7. Repeat.

This ingenious loop relies on Woe Strider to continually sacrifice Tarpan, whose death triggers are intercepted by Mortuary to neatly recycle it right back to the top of your library. Meanwhile, Gwenom, Remorseless transforms that top-deck placement into an alternative casting method, allowing you to bypass mana costs entirely by paying life instead of mana. Because Tarpan's natural lifegain offsets the life payment required by Gwenom, you achieve a self-sustaining engine that endlessly cycles through the deck to generate a storm of sacrifice, death, and entry triggers.
