Sefris of the Hidden Ways + Radiant Solar + Mirror Image + Clone

Sefris of the Hidden Ways

Radiant Solar

Mirror Image

Clone

How it works

1. Put any nontoken creature onto the battlefield.
2. When the creature enters, Radiant Solar, Mirror Image and Clone 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 Mirror Image trigger, venturing into the Oubliette room, causing you to discard a card and then sacrifice Radiant Solar.
5. Resolve the Clone 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 brilliant loop harnesses the relentless dungeon-delving engine of Sefris of the Hidden Ways to infinitely recycle your key threats. Whenever any creature enters the battlefield, Radiant Solar steps in alongside Mirror Image and Clone to rapidly push you through the Tomb of Annihilation, utilizing the legend rule with the resulting The Atropal tokens to quietly tuck creatures into your graveyard. This clever sacrifice effortlessly triggers Sefris of the Hidden Ways' second ability, allowing you to continually pull Radiant Solar straight back to the battlefield to restart the cycle and overwhelm your opponents with near-infinite enters-the-battlefield, death, and sacrifice triggers.
