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 Ravenloft Adventurer from your graveyard onto the battlefield.
When Ravenloft Adventurer enters, it triggers once and Preston triggers twice due to Delney.
Holding priority, activate Bartolomé del Presidio by sacrificing Ravenloft Adventurer.
Resolve a Preston trigger, creating a token copy of Ravenloft Adventurer that is a 0/1 Illusion.
When the Ravenloft Adventurer token enters, it triggers twice due to Delney.
Resolve the Ravenloft Adventurer token triggers, venturing into Undercity twice.
Resolve the second Preston trigger from step 5, creating a token copy of Ravenloft Adventurer that is a 0/1 Illusion.
Repeat steps 8 and 9 one additional time.
Resolve the Ravenloft Adventurer trigger from step 5, venturing into Undercity and completing Undercity.
Repeat from step 2.
This elaborate loop centers on Sefris of the Hidden Ways and Delney, Streetwise Lookout, whose static ability to double low-power triggers is the engine that supercharges your board. By completing a dungeon, Sefris's return ability triggers twice, allowing you to cycle Ravenloft Adventurer and another creature right back from the graveyard, while Preston, the Vanisher swoops in to instantly clone the Adventurer into 0/1 Illusion tokens whenever it enters uncast. As you sacrifice those tokens to Bartolomé del Presidio to fuel your engine, the repeated entry of the Ravenloft Adventurer triggers lets you rapidly venture through and complete the Undercity dungeon over and over again, effortlessly generating infinite resources and sweeping your library.
