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

This intricate engine turns the act of completing a dungeon into an endless cascade of value, completely breaking the game wide open. Delney, Streetwise Lookout acts as the ultimate amplifier, doubling the creature-based triggered abilities of both Sefris of the Hidden Ways and the entering Aarakocra Sneak. When Sefris brings back Aarakocra Sneak, Preston, the Vanisher swoops in to manufacture 0/1 Illusion copies of it, while Umbral Collar Zealot stands ready to neatly sacrifice them. The result is a self-sustaining loop that rockets you through the Undercity over and over, generating endless triggers, tokens, and resources until you overwhelm the table entirely.
