Mortuary + Daxos, Blessed by the Sun + Bile Urchin + Gwenom, Remorseless

Mortuary

Daxos, Blessed by the Sun

Bile Urchin

Gwenom, Remorseless

How it works

1. Activate Bile Urchin by sacrificing it.
2. When Bile Urchin dies, Mortuary and Daxos trigger.
3. Resolve the Mortuary trigger, putting Bile Urchin from your graveyard onto the top of your library.
4. Resolve the Daxos trigger, causing you to gain 1 life
5. Resolve the Bile Urchin ability.
6. Cast Bile Urchin from the top of your library by paying 1 life.
7. When Bile Urchin enters, Daxos triggers, causing you to gain 1 life.
8. Repeat.

This loop turns a humble goblin into a lethal engine by turning your graveyard into a revolving door. When you activate Bile Urchin, sacrificing it to drain an opponent, Mortuary immediately catches the spirit and tucks the card right back onto the top of your library. From there, Gwenom, Remorseless lets you recast the Urchin from the top of your library for a sliver of life instead of mana, smoothly bypassing traditional costs. Meanwhile, Daxos, Blessed by the Sun quietly watches the cycle unfold, generating a continuous stream of life whenever the Urchin enters or leaves the battlefield to offset any costs and keep your health total secure.
