There are a few over arching themes about the kind of cards cut and added here.
CUTS:
Adds:
-Minor archetype support. Some of the Perrie counter cards got some added support, with cards like Sanctuary Smasher also adding keywords into your graveyard. +1/+1 counter decks with Pridemalkin, token decks with Battle Screech, self discard decks with Nagging Thoughts, and the famous Blood Artist for sacrifice decks all support archetypes.
-Graveyard matters more! I love being able to use your graveyard as a resource, and cards like Lotus-Eye Mystics, Ishkanah, Grafwidow, and Life from the Loam all go in different decks while accomplishing that same goal.
