Preston, the Vanisher

Delney, Streetwise Lookout

Sefris of the Hidden Ways

Phyrexian Altar

Stirring Bard

How it works

1. Complete a dungeon.
2. Sefris' second ability triggers twice due to Delney.
3. Resolve the first trigger, returning up to one other creature from your graveyard to the battlefield.
4. Resolve the second trigger, returning Stirring Bard from your graveyard onto the battlefield.
5. When Stirring Bard enters, it and Preston trigger twice due to Delney.
6. Holding priority, activate Phyrexian Altar by sacrificing Stirring Bard.
7. Resolve a Preston trigger, creating a token copy of Stirring Bard that is a 0/1 Illusion.
8. When the Stirring Bard token enters, it triggers twice due to Delney.
9. Resolve the Stirring Bard token triggers, venturing into Undercity twice.
10. Resolve the second Preston trigger from step 5, creating a token copy of Stirring Bard that is a 0/1 Illusion.
11. Repeat steps 8 and 9 one additional time.
12. Resolve the first Stirring Bard trigger from step 5, venturing into Undercity and completing Undercity.
13. Repeat from step 2.

This intricate loop turns the humble act of completing a dungeon into an endless engine of resurrection and dungeon-crawling. With Sefris of the Hidden Ways ready to pull creatures from your graveyard, Delney, Streetwise Lookout acts as the ultimate multiplier, doubling both Sefris's dungeon completion triggers and the creature abilities that follow. When Stirring Bard enters the battlefield, its initiative-taking ability and Preston, the Vanisher's uncast-copy trigger both double under Delney's watchful eye, ensuring you generate an army of 0/1 Illusion copies of the Bard. You can sacrifice these Illusions and the Bards themselves to Phyrexian Altar to fund your mana needs, while the repetitive dungeon ventures through the Undercity continuously complete dungeons to fuel Sefris all over again.
