Yosei, the Morning Star + Gift of Immortality + Altar of Dementia

Yosei, the Morning Star

Gift of Immortality

Altar of Dementia

How it works

1. Activate Altar of Dementia by sacrificing Yosei.
2. When Yosei dies, it and Gift of Immortality trigger.
3. Resolve the Yosei trigger, causing the next player in turn order to skip their next untap step.
4. Resolve the Gift of Immortality trigger, returning Yosei from your graveyard to the battlefield.
5. Resolve the Altar of Dementia ability.
6. At the beginning of the end step, Gift of Immortality triggers, returning it from your graveyard to the battlefield attached to Yosei.
7. Repeat during each turn unless you are the next player in turn order.

This wicked loop locks an opponent entirely out of their resources by weaponizing the recursion of Gift of Immortality. Each time you sacrifice Yosei, the Morning Star to Altar of Dementia, its death triggers both its own oppressive lock—forcing the target player to tap down five permanents and skip their untap step—and the enchantment's ability to bring the dragon right back to the battlefield. Because Gift of Immortality neatly returns itself to attach to Yosei at the beginning of the end step, you can seamlessly repeat this sacrifice loop on every turn to completely freeze your opponents out of the game.
