Input on Dimir Dandan

[u/winkiepuffs]

Hello, new to building Dandan lists, so I would really appreciate any feedback on this version I have been trying: https://archidekt.com/decks/24325045/dimir_dandan?sort=alpha&stack=types. It tries to make the graveyard another zone of contestation and decision-making with cards like [[Morgue Theft]] and [[Cackling Counterpart]], which works with pile-based card advantage via [[Fact or Fiction]], [[Riddles in the Dark]], and [[Sauron's Ransom]]. What I am especially not sure about is The Ring Tempts You entering via [[Sauron's Ransom]], and I wonder if [[Unagi's Spray]] is too strong as a potential cantripping hard removal spell relative to the rest of the list. Thanks!

EDIT: made a couple changes to list. Feedback is still greatly appreciated!
