[Commander] Spooky, Evil Dead, Horror Deck Building Advice

Hello Lovers of Horror and Spooky Enjoyers,

I am building this deck to be stacked with spooky cards. Nightmares, Horrors, and Demons specifically with thematic cards and rooms. Does anyone have suggestions for cards I could replace in this deck? Any insight into how well structured this deck is currently? I'm trying to float around Bracket 2 or 3 if that helps. Additionally, I don't want to add or replace a card with Tergrid, God of Fright.
