I love this decklist before DTK so the mainboard is pretty similar to the one posted by The Mana Source Here
The only change that I made is that I removed an arbor colossus and added Dragonlord Atarka. I think a single one is a great addition although slightly expensive but doable I think in this list.
The only thing I need is more sideboard options against control. Let me know what you think.
I am going to take this to the next game day at least.
