Your mana base seems a bit off to me, you have 16 blue and white sources, but only 9 black sources.... but most of your early spells are black... I feel that the white and black numbers in mana need to be balanced more... or the spell set completely reworked. Personally I would add more black as I assume hitting Yahenni's Expetise is more important than hittinh fumigate as othewise you would not run them in those numbers.


You have 5 Collective Brutality, so you have an extra slot as well.


Any reason you are not running a man land?


Completely contradictary question, but does this deck gain from being 3 colours, or would two have sufficed. For me as a designer, reasoning is key... let me know why you chose it as is and I can help and provide guidance.


I need you to give me some background, what are you struggling with, what is not working so well, what are you still looking for... I am not doing testing myself so can only give feedback on what you tell and show me. Talk me through some of the stuff you are trying to correct, and we can work from there.
