This loop leverages the synergy between Leonardo, Sewer Samurai and Solemnity to completely bypass the finality counters that would normally exile your creatures, turning your graveyard into an endless resource. By utilizing Woe Strider to feed the machine, you can repeatedly sacrifice Crookshank Kobolds—which costs zero mana to cast directly from your graveyard thanks to Leonardo's static ability—generating infinite sacrifice triggers, death triggers, and scry 1 filters. Solemnity’s passive lockdown is the linchpin here, ensuring that the finality counters can never touch the Kobolds as they re-enter the battlefield, allowing the recursion to run infinitely.
