Sefris of the Hidden Ways + Radiant Solar + Stunt Double + Vesuvan Doppelganger

Sefris of the Hidden Ways

Radiant Solar

Stunt Double

Vesuvan Doppelganger

How it works

1. Put any nontoken creature onto the battlefield.
2. When the creature enters, Radiant Solar, Stunt Double and Vesuvan Doppelganger 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 Stunt Double trigger, venturing into the Oubliette room, causing you to discard a card and then sacrifice Radiant Solar.
5. Resolve the Vesuvan Doppelganger 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 intricate loop revolves around Sefris of the Hidden Ways, whose passive venture ability converts creature movements into dungeon progression while her *Create Undead* trigger brings fallen allies back from the dead upon completing a dungeon. By casting a creature to set off a cascade of triggers, Radiant Solar immediately ventures deeper into the Tomb of Annihilation. Meanwhile, clever copy effects from Stunt Double and Vesuvan Doppelganger allow them to enter as clones and rapidly push you through the dungeon's remaining chambers—ultimately culminating in the creation of a legendary The Atropal token that finishes the dungeon. The legend rule then forces the excess token into the graveyard, which cleanly satisfies Sefris of the Hidden Ways' graveyard condition to resurrect Radiant Solar and seamlessly loop the entire sequence for devastating effect.
