Radiant Solar + Sefris of the Hidden Ways + Displacer Beast + All-Fates Stalker

Radiant Solar

Sefris of the Hidden Ways

Displacer Beast

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 Displacer Beast 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 Displacer Beast to be returned to the battlefield from exile.
6. When Displacer Beast enters, it and Radiant Solar trigger.
7. Resolve the Displacer Beast 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 Displacer Beast 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 brilliant dungeon-delving loop transforms the clever use of temporary exile into a self-sustaining engine. By casting All-Fates Stalker, you trigger its own entrance alongside Radiant Solar's continuous ability to venture into dungeons. When the Stalker temporarily exiles Displacer Beast, the resulting dungeon progress forces the Stalker's own sacrifice, which in turn returns Displacer Beast to the battlefield. This re-entry sparks both Displacer Beast and Radiant Solar anew, rapidly completing the Tomb of Annihilation to trigger Sefris of the Hidden Ways' powerful graveyard recursion—pulling All-Fates Stalker right back into play to keep the endless cycle moving.
