Preston, the Vanisher

Delney, Streetwise Lookout

Sefris of the Hidden Ways

Woe Strider

Ravenloft Adventurer

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 Ravenloft Adventurer from your graveyard onto the battlefield.
5. When Ravenloft Adventurer enters, it triggers once and Preston triggers twice due to Delney.
6. Holding priority, activate Woe Strider by sacrificing Ravenloft Adventurer.
7. Resolve a Preston trigger, creating a token copy of Ravenloft Adventurer that is a 0/1 Illusion.
8. When the Ravenloft Adventurer token enters, it triggers twice due to Delney.
9. Resolve the Ravenloft Adventurer token triggers, venturing into Undercity twice.
10. Resolve the second Preston trigger from step 5, creating a token copy of Ravenloft Adventurer that is a 0/1 Illusion.
11. Repeat steps 8 and 9 one additional time.
12. Resolve the Ravenloft Adventurer trigger from step 5, venturing into Undercity and completing Undercity.
13. Repeat from step 2.

This intricate loop turns Sefris of the Hidden Ways into an absolute engine for dungeon-delving dominance, fueled by the recursive sacrifice outlet of Woe Strider. Delney, Streetwise Lookout acts as a vital amplifier here, doubling the triggered abilities of both Sefris and your entering creatures so that a single dungeon completion snowballs out of control. When Sefris pulls Ravenloft Adventurer from the graveyard, Preston, the Vanisher swoops in to multiply those entry triggers into an avalanche of Illusion token copies. Meanwhile, Delney's passive power-based evasion and Ravenloft Adventurer's graveyard-hate and attack triggers ensure your board stays protected and your opponents slowly bleed out as you loop endlessly.
