Sefris of the Hidden Ways + Radiant Solar + Mirror Image + Naga Fleshcrafter

Sefris of the Hidden Ways

Radiant Solar

Mirror Image

Naga Fleshcrafter

How it works

1. Put any nontoken creature onto the battlefield.
2. When the creature enters, Radiant Solar, Naga Fleshcrafter and Mirror Image 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 Naga Fleshcrafter trigger, venturing into the Oubliette room, causing you to discard a card and then sacrifice Radiant Solar.
5. Resolve the Mirror Image 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 leverages Sefris of the Hidden Ways as your engine, transforming repetitive dungeon completions into a relentless loop of creature resurrection. By using Mirror Image and Naga Fleshcrafter to continuously copy and re-evaluate your board state, you rapidly race through the Tomb of Annihilation dungeon, driven along the way by Radiant Solar's triggers. Whenever the legend rule forces you to sacrifice an excess copy, the resulting trip to the graveyard triggers Sefris of the Hidden Ways's second ability to pull Radiant Solar straight back to the battlefield, restarting the whole cycle.
