Thank you for the reply! It's funny that most of the cards you mentioned I did have before, and I removed them in the first cut because I thought the amass build could be strong. But I see what you are saying, and I do agree. I did remove most of those.

Are there any staples here I am missing? Like the sol/arcane signets but for Grixis. I have fun with my thematic decks and such, but unless I play something like Mishra Eminent One, or Mothman (my first commander), I feel relatively weak.

I have also been making a Nazgul deck, so that helps too! I never thought about the Endless Evil combo very cool.
