Hello everybody! Here is my Tivit, Seller of Secrets Commander deck. Please give me suggestions, feedback, and opinions on what I can do better. Does any of these cards not synergize well with my deck? Am I missing any cards that I should add to hopefully increase the strength and speed of my deck, and my ability to ramp? Please let me know
