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 Aarakocra Sneak from your graveyard onto the battlefield.
When Aarakocra Sneak enters, it and Preston trigger twice due to Delney.
Holding priority, activate Woe Strider by sacrificing Aarakocra Sneak.
Resolve a Preston trigger, creating a token copy of Aarakocra Sneak that is a 0/1 Illusion.
When the Aarakocra Sneak token enters, it triggers twice due to Delney.
Resolve the Aarakocra Sneak token triggers, venturing into Undercity twice.
Resolve the second Preston trigger from step 5, creating a token copy of Aarakocra Sneak that is a 0/1 Illusion.
Repeat steps 8 and 9 one additional time.
Resolve the first Aarakocra Sneak trigger from step 5, venturing into Undercity and completing Undercity.
Repeat from step 2.
This intricate loop starts humming once Sefris of the Hidden Ways completes a dungeon, triggering her ability twice to pull creatures straight from your graveyard thanks to Delney, Streetwise Lookout doubling power-2-or-less triggers. As Aarakocra Sneak repeatedly enters the battlefield, Delney makes both its initiative-taking entry and Preston, the Vanisher's copy-making trigger happen twice over. Meanwhile, Woe Strider acts as your reliable sacrifice outlet to feed the loop, letting you continuously recycle the Sneak and its 0/1 Illusion tokens to race endlessly through the Undercity dungeon and generate absurd amounts of value.
