Activate Woe Strider by sacrificing Crookshank Kobolds.
When Crookshank Kobolds dies, Mortuary and Remembrance trigger.
Resolve the Mortuary trigger, putting Crookshank Kobolds from your graveyard on top of your library.
Resolve the Remembrance trigger, searching your library for Crookshank Kobolds and putting it into your hand.
Resolve the Woe Strider ability, causing you to scry 1.
Cast Crookshank Kobolds by paying 0.
Repeat.
This ingenious loop relies on free creature sacrifice to generate an endless cycle of death and resurrection, turning a humble zero-mana creature into a bottomless engine of triggers. When you feed Crookshank Kobolds to Woe Strider's sacrifice ability, Mortuary immediately intercepts the creature as it hits the graveyard and places it right back on top of your library. Simultaneously, Remembrance catches the death trigger, letting you search out that exact same card and draw it straight into your hand. Because the Kobolds cost nothing to cast, you can instantly replay them and repeat the entire process, fueling endless scrys and sacrifice effects.
