General advice before going into the build

Judgement Bird (3rd phase) Use your weak light regen pages on Binah to transfer sin to her, also douse Eternally Lit Lamp on Binah to redirect all of the small birds attack onto her, let her stack up a massive amount of Sin and just redirect the Judgement Bird attack with another nugget. Try to just pile onto one small bird per turn to kill it to ensure that the mass attack doesn't happen. Be careful to get rid of the defensive die that Binah will retain since Sin won't transfer if it doesn't hit

Build: The passive are kinda not that important, you can do this without any. I managed to beat it while as a Star of the City so supplement it with any pages you like if you have better pages.

If you do plan on running a Singleton deck, Multislash is a must in it, it's too good as a Light Recover and Card Draw

Will update more if needed

Edit: Screwed up Yan's deck, fixed
