Sefris of the Hidden Ways + Radiant Solar + Sun Titan + Fell Stinger + Glasspool Mimic // Glasspool Shore

Sefris of the Hidden Ways

Radiant Solar

Sun Titan

Fell Stinger

Glasspool Mimic // Glasspool Shore

How it works

1. Cast Sun Titan by paying 4.
2. When Sun Titan enters the battlefield, it, Radiant Solar and Glasspool Mimic 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 Glasspool Mimic 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 Glasspool Mimic 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 Glasspool Mimic 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 ingenious loop turns a single Sun Titan entry into an unstoppable descent through the dungeon depths. As Sun Titan and Glasspool Mimic (copying the Titan) re-enter the battlefield alongside Radiant Solar, their stacked enters-the-battlefield triggers rapidly pace you through Tomb of Annihilation. Fell Stinger plays a crucial sacrifice role here, exploiting itself to feed the engine while triggering card draw, which in turn sends creature cards into your graveyard to satisfy Sefris of the Hidden Ways. Once the dungeon is complete, Sefris's *Create Undead* ability triggers to pull Sun Titan right back out of the graveyard, restarting the whole cycle for near-infinite resources and doom.
