Sefris of the Hidden Ways + Radiant Solar + Evil Twin + Vizier of Many Faces

Sefris of the Hidden Ways

Radiant Solar

Evil Twin

Vizier of Many Faces

How it works

1. Put any nontoken creature onto the battlefield.
2. When the creature enters, Radiant Solar, Evil Twin and Vizier of Many Faces each trigger.
3. Resolve the Radiant Solar trigger, causing you to venture into Tomb of Annihilation and into the Trapped Entry room, causing each player to lose 1 life.
4. Resolve the Evil Twin trigger, venturing into the Oubliette room, causing you to discard a card and then sacrifice Radiant Solar.
5. Resolve the Vizier of Many Faces trigger, venturing into the Cradle of the Death God room, creating a 4/4 legendary The Atropal creature token and completing Tomb of Annihilation.
6. If you control two or more The Atropal tokens, put all but one into your graveyard due to the legend rule.
7. Sefris' second ability triggers, returning Radiant Solar from your graveyard to the battlefield.
8. Repeat from step 2.

This clever loop transforms Sefris of the Hidden Ways into an engine of endless dungeon crawls by continuously cycling Radiant Solar through the graveyard. When a creature enters, Radiant Solar, Evil Twin, and Vizier of Many Faces trigger together to rapidly advance you through the Tomb of Annihilation. Evil Twin plays a vital role by sacrificing Radiant Solar mid-journey, while Vizier of Many Faces creates a legendary The Atropal token that immediately triggers the legend rule if you control another, sending excess copies away. That death pushes a creature into your graveyard to satisfy Sefris of the Hidden Ways' first ability, which in turn unlocks Sefris's second ability to fish Radiant Solar right back to the battlefield and start the cycle anew.
