@Iron_eye2 The issue with either of those additions is the added clunckyness and win more nature of the cards. I’m sure that you noticed that this deck runs an average CMC of 1.26. We can utilize Coretapper to empower our cheap X drop artifacts and ultimately create pseudo ramp. Our lock is not insanely consistent but it is reliable enough given what other measures we have to lock out our opponent. Most interaction occurs in the 1 or 3 mana slots, we abuse this fact by running effectively no 1 drops or 3 drops such that we maximize the value of our Chalice of the Voids. I can’t see makeong the additions that you mentioned because I do not believe that either of them serve to offer a better alternative to what we currently run. I appreciate the input though.

I like this deck! It's similar to my Kurkesh with Cannon and Key that also revolves around Coretapper and Astral Cornucopia, and is kinda like a distand budged relative of this.

Salutations for finding Erayo, Soratami Ascendant. It's a cool card and I'm glad to find out about it!

I even have a suggestion for you: Freejam Regent. It dodges almost all removal in modern and is a solid finisher.
