Preston, the Vanisher + Delney, Streetwise Lookout + Sefris of the Hidden Ways + Goblin Bombardment + Stirring Bard

Preston, the Vanisher

Delney, Streetwise Lookout

Sefris of the Hidden Ways

Goblin Bombardment

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 Goblin Bombardment 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 dazzling loop relies on Sefris of the Hidden Ways and Delney, Streetwise Lookout working in tandem to multiply your dungeon completions, turning every recursion into a cascading engine. Because Delney doubles the triggers of low-power creatures like Stirring Bard, its entry takes you deep into the Undercity while Preston, the Vanisher continuously manufactures 0/1 Illusion copies of the Bard without ever needing you to cast it from your hand. You can sacrifice these Illusions and the Bards at will to Goblin Bombardment to clear the board and deal infinite damage, fueling a permanent self-sustaining cycle that completes dungeons over and over again.
