Sefris of the Hidden Ways + Radiant Solar + Progenitor Mimic + Chameleon, Master of Disguise

Sefris of the Hidden Ways

Radiant Solar

Progenitor Mimic

Chameleon, Master of Disguise

How it works

1. Put any nontoken creature onto the battlefield.
2. When the creature enters, Radiant Solar, Chameleon and Progenitor Mimic 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 Chameleon trigger, venturing into the Oubliette room, causing you to discard a card and then sacrifice Radiant Solar.
5. Resolve the Progenitor Mimic 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 loop turns a simple creature entry into a relentless cycle of dungeon-crawling doom, powered by the synergy between Sefris of the Hidden Ways and Radiant Solar. Every time a creature enters, Radiant Solar, Chameleon, Master of Disguise, and Progenitor Mimic trigger simultaneously to rapidly advance you through the Tomb of Annihilation. Chameleon, Master of Disguise helps accelerate your progress and facilitates the sacrifice of Radiant Solar, sending the Angel straight to the graveyard. This death triggers Sefris of the Hidden Ways' second ability, while Progenitor Mimic ensures legendary token replication that continuously forces sacrifices and recycles your resources.
