How it works
Complete a dungeon.
Sefris' second ability triggers twice due to Delney.
Resolve the first trigger, returning up to one other creature from your graveyard to the battlefield.
Resolve the second trigger, returning Goliath Paladin from your graveyard onto the battlefield.
When Goliath Paladin enters, it triggers once and Preston triggers twice due to Delney.
Holding priority, activate Bartolomé del Presidio by sacrificing Goliath Paladin.
Resolve a Preston trigger, creating a token copy of Goliath Paladin that is a 0/1 Illusion.
When the Goliath Paladin token enters, it triggers twice due to Delney.
Resolve the Goliath Paladin token triggers, venturing into Undercity twice.
Resolve the second Preston trigger from step 5, creating a token copy of Goliath Paladin that is a 0/1 Illusion.
Repeat steps 8 and 9 one additional time.
Resolve the Goliath Paladin trigger from step 5, venturing into Undercity and completing Undercity.
Repeat from step 2.
This intricate loop relies on repeatedly cycling Goliath Paladin through your graveyard and back to the battlefield to continually restart and complete the Undercity dungeon. Preston, the Vanisher acts as your token generator, producing 0/1 Illusion copies of the Paladin whenever it enters uncast, while Bartolomé del Presidio provides a reliable outlet to sacrifice those creatures on command. Delney, Streetwise Lookout is the linchpin that doubles both Preston's copy triggers and Sefris of the Hidden Ways' dungeon-advancing triggers, allowing you to bypass normal restrictions. Finally, Sefris of the Hidden Ways rewards your constant dungeon completions by repeatedly pulling Goliath Paladin back from the graveyard, sustaining an infinite engine that sweeps through the entire dungeon layout over and over again.
