LOVE the idea behind the deck, so that's an immediate +1 from me! Have you considered maybe one or two of the swords (Fire and Ice, Feast and Famine, etc.)? Also, something like Ugin, the Ineffable could help you cast your equipments easier. Overall, it's the beginnings of something great!

Thanks for the suggestions! I've been a huge fan of their books since grade school, so the moment they were announced, I knew I had to try and build a deck around them.

I've thought about including the swords, but I've held off because of the cost of the cards, but I'm starting to lean into it because of the other high cost cards I've now included (stoneforged mystic, and Mirri, for example)

I will DEFINITELY work in Ugin, never even heard of that card before now. Thank you for the suggestions and feedback!

I would suggest increasing the mana base. 31 lands seems a little low. I wouldnt drop below 36
