The K Command splash is spicy and I love it.
I was wondering why Burn was difficult with 4 Collective Brutality, but then I saw 4 SPox, 3 Thoughtseize, 4 Fetchlands and a Dismember. That's 14-18 life you are conceding even before 2 copies of Toxic Deluge. That mana base doesn't hold up well against Price of Progress either.
Good job on the rest. Bomberman is probably pretty easy with a Nether Void in play. The other two matches can be difficult, especially any Depths variant.
I want to K Command a Batterskull pretty badly.
Sinkhole seems odd to me in the board but it might make sense. My mana base strips a lot of the nonbasics- so with a red splash I would be tempted to consider Blood Moon.
