Sefris of the Hidden Ways + Radiant Solar + Pirated Copy + Naga Fleshcrafter

Sefris of the Hidden Ways

Radiant Solar

Pirated Copy

Naga Fleshcrafter

How it works

1. Put any nontoken creature onto the battlefield.
2. When the creature enters, Radiant Solar, Pirated Copy and Naga Fleshcrafter 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 Pirated Copy trigger, venturing into the Oubliette room, causing you to discard a card and then sacrifice Radiant Solar.
5. Resolve the Naga Fleshcrafter 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.
