Sefris of the Hidden Ways + Radiant Solar + Dack's Duplicate + Omni-Changeling
How it works
- Put any nontoken creature onto the battlefield.
- When the creature enters, Radiant Solar, Omni-Changeling and Dack's Duplicate each trigger.
- 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.
- Resolve the Omni-Changeling trigger, venturing into the Oubliette room, causing you to discard a card and then sacrifice Radiant Solar.
- Resolve the Dack's Duplicate trigger, venturing into the Cradle of the Death God room, creating a 4/4 legendary The Atropal creature token and completing Tomb of Annihilation.
- If you control two or more The Atropal tokens, put all but one into your graveyard due to the legend rule.
- Sefris' second ability triggers, returning Radiant Solar from your graveyard to the battlefield.
- Repeat from step 2.
This clever loop hinges on Sefris of the Hidden Ways and her ability to resurrect creatures whenever you complete a dungeon, which is fueled by a cascading wave of dungeon-venturing triggers whenever a creature enters the battlefield. By casting any nontoken creature, you trigger Radiant Solar, Omni-Changeling (copying a relevant piece or setting up the chain), and Dack's Duplicate simultaneously. This multi-trigger allows you to rapidly advance through the Tomb of Annihilation: Radiant Solar ventures into the first room, Omni-Changeling's entry triggers a sacrificial setback by discarding a card and ditching Radiant Solar into the graveyard, and Dack's Duplicate pushes you across the finish line into the Cradle of the Death God. Completing the dungeon triggers Sefris of the Hidden Ways to immediately pull Radiant Solar right back out of the graveyard onto the battlefield, restarting the entire engine and letting you generate near-infinite enter-the-battlefield, death, and sacrifice triggers alongside sweeping life loss for your opponents.
