Preston, the Vanisher

Delney, Streetwise Lookout

Sefris of the Hidden Ways

Woe Strider

Feywild Caretaker

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

This intricate loop starts humming once you complete a dungeon, allowing Sefris of the Hidden Ways to bring back Feywild Caretaker while Delney, Streetwise Lookout doubles up the trigger to also recur another creature from your graveyard. As Feywild Caretaker enters the battlefield, Preston, the Vanisher creates a 0/1 copy of it—doubled thanks to Delney's static ability—while Woe Strider stands ready to sacrifice the original to feed the engine. By repeatedly copying the Caretaker token and cycling through the Undercity dungeon, Delney's amplification ensures you infinitely venture, ultimately generating an overwhelming cascade of mana, tokens, card draws, and permanent recursion.
