Radiant Solar + Sefris of the Hidden Ways + Eccentric Apprentice + All-Fates Stalker

Radiant Solar

Sefris of the Hidden Ways

Eccentric Apprentice

All-Fates Stalker

How it works

1. Cast All-Fates Stalker by paying its mana cost.
2. When All-Fates Stalker enters, it and Radiant Solar trigger.
3. Resolve the All-Fates Stalker trigger, exiling Eccentric Apprentice until All-Fates Stalker leaves the battlefield.
4. Resolve the Radiant Solar trigger, venturing into the Oubliette room, causing you to discard a card and then sacrifice All-Fates Stalker.
5. All-Fates Stalker leaves the battlefield, causing Eccentric Apprentice to be returned to the battlefield from exile.
6. When Eccentric Apprentice enters, it and Radiant Solar trigger.
7. Resolve the Eccentric Apprentice trigger, venturing into the Cradle of the Death God room, creating a 4/4 legendary The Atropal creature token and completing Tomb of Annihilation.
8. If you control two or more The Atropal tokens, put all but one into your graveyard due to the legend rule.
9. Sefris' second ability triggers, returning All-Fates Stalker from your graveyard to the battlefield.
10. When All-Fates Stalker enters, it and Radiant Solar trigger.
11. Resolve the All-Fates Stalker trigger, exiling Eccentric Apprentice until All-Fates Stalker leaves the battlefield.
12. Resolve the Radiant Solar trigger from step 10, venturing into Tomb of Annihilation and into the Trapped Entry room, causing each player to lose 1 life.
13. Resolve the Radiant Solar trigger from step 6, venturing into the Oubliette room, causing you to discard a card and then sacrifice All-Fates Stalker.
14. Repeat from step 5.

This ingenious loop transforms dungeon exploration into a self-sustaining engine by leveraging Sefris of the Hidden Ways as your graveyard-recursion anchor. Every time All-Fates Stalker enters the battlefield, it exiles Eccentric Apprentice until it leaves, while Radiant Solar reliably advances your progress through the dungeon. The sacrifice triggered by the Oubliette sends All-Fates Stalker straight to the graveyard, which in turn triggers Sefris of the Hidden Ways to bring it right back—fueling a continuous loop that repeatedly completes dungeons, triggers the "Create Undead" return ability, and rapidly drains your opponents' life totals.
