Preston, the Vanisher + Delney, Streetwise Lookout + Sefris of the Hidden Ways + Undermountain Adventurer + Carrion Feeder
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 Undermountain Adventurer from your graveyard onto the battlefield.
- When Undermountain Adventurer enters, it triggers once and Preston triggers twice due to Delney.
- Holding priority, activate Carrion Feeder by sacrificing Undermountain Adventurer.
- Resolve a Preston trigger, creating a token copy of Undermountain Adventurer that is a 0/1 Illusion.
- When the Undermountain Adventurer token enters, it triggers twice due to Delney.
- Resolve the Undermountain Adventurer token triggers, venturing into Undercity twice.
- Resolve the second Preston trigger from step 5, creating a token copy of Undermountain Adventurer that is a 0/1 Illusion.
- Repeat steps 8 and 9 one additional time.
- Resolve the Undermountain Adventurer trigger from step 5, venturing into Undercity and completing Undercity.
- Repeat from step 2.
This intricate loop is entirely supercharged by Delney, Streetwise Lookout, whose static ability doubles every single creature-based trigger you care about, letting Sefris of the Hidden Ways and Preston, the Vanisher pull double duty on every cycle. When Undermountain Adventurer enters the battlefield—initially brought back by Sefris of the Hidden Ways completing a dungeon—its own initiative trigger and Preston's token-copy creation both double to maximize your dungeon progress. By utilizing Carrion Feeder to neatly sacrifice the original Undermountain Adventurer, you keep the graveyard stocked so Sefris of the Hidden Ways can endlessly loop the adventurer back to the battlefield while Preston, the Vanisher floods the board with 0/1 Illusion copies of it.
