The two commanders looks really interesting to me, they seems to synergize pretty well, but I never had the chance to try.
Have you had the opportunity to playtest yet?
By the way from the post I was not able to get which is the format, I suppose it is the mtgo 1 vs 1 variant. (Here in Italy Leviathan and duel commander are fair more popular though). In this case you have to keep off the sol ring, since is banned, and also the spellskite because it doesn't respect the color identity of your commanders.
So said I like your concept of deck and most of the cards, except for few of them:
Kataki, War's Wage is a bit overrated in commander, while most of the time it will be just a 2/1 with no effect or it will arrive too late when the opponent could choose to pay a bunch of mana or just spend a removal for him!
Silverchase Fox is not worth in my opinion, just go for Kami of Ancient Law so you will not need to keep the two mana open in any moment. Yeah it is true, you loose the option of removing a God but I don't think the meta justify this choice.
Then I suggest you to focus more on creatures with low converted mana cost ( <= 2), because basically you always want to cast Tymna, the Weaver on turn 3 and attack at least with one creature on that turn. Also, you could exploit the black discard to constantly have information about the opponent's hand and remove threats directly from there! Tidehollow Sculler is a must

Let me know if you upgraded the list!
