Fell Stinger

How it works

1. Cast Sun Titan by paying 4.
2. When Sun Titan enters the battlefield, it, Radiant Solar and Mirror Image trigger.
3. Resolve the Sun Titan trigger, returning Fell Stinger from your graveyard to the battlefield.
4. When Fell Stinger enters the battlefield, its exploit ability, Radiant Solar and Mirror Image trigger.
5. Resolve the Fell Stinger trigger, causing you to sacrifice it.
6. Fell Stinger's second ability triggers, causing target player to draw 2 cards and lose 2 life.
7. Resolve the Mirror Image trigger from step 4, causing you to venture into the "Trapped Entry" room of Tomb of Annihilation, causing each player to lose 1 life.
8. Resolve the Radiant Solar trigger from step 4, causing you to venture into the "Veils of Fear" room, causing each player to discard a card or lose 2 life.
9. Resolve the Mirror Image trigger from step 2, causing you to venture into the "Sandfall Cell" room, causing you to sacrifice Sun Titan and each opponent to either sacrifice a creature, artifact or land, or lose 2 life.
10. Resolve the Radiant Solar trigger from step 2, causing you to venture into the "Cradle of the Death God" room, creating a legendary 4/4 The Atropal creature token and completing Tomb of Annihilation.
11. Sefris' second ability triggers, returning Sun Titan from your graveyard to the battlefield.
12. Repeat from step 2.

This elegant loop hinges on Sun Titan repeatedly pulling Fell Stinger from the graveyard to fuel exploit sacrifices, which are doubled up by Mirror Image copying the action alongside Radiant Solar's continuous venture triggers. As you blaze through the Tomb of Annihilation dungeon, Sefris of the Hidden Ways watches creature cards enter your graveyard to trigger dungeon progress and ultimately resurrect Sun Titan once the dungeon is complete. This creates a self-sustaining engine that cycles your permanent back into play while churning out near-infinite card draw, life loss, and death triggers.
