Ascendant Evincar is a little redundant in here with all your mono red vampires because he -1/-1's them also.

You are correct sir. Switched it out for Door of Destinies

If you're on a budget, Crypt Ghast would be a great addition. Also Beacon of Unrest to have a multiple use and versatile graveyard recursion.

Both would fit right in. A lot of the cards in this deck are from a pre-existing deck my Nephew-in-law made (he got all the expensive demons and such). I think I like that Beacon better than the Door of Destinies I just put in. Gonna give back a few cards and use both these I think.

I was playtesting this with my Prime Speaker Zegana deck, and it seemed like your deck doesn't have any way to deal with something like Food Chain + Misthollow Griffin to draw the deck with Prime Speaker. I'm not sure what to say about enchantment destruction in Rakdos, but maybe you could try Spine of Ish Sah ?

Here's my deck if you'd like to look at it:

Thinking about a Pithing Needle for stuff like that, but yeah....this deck doesn't have a lot of anti-enchantment. That Food Chain is an amazing spell.
