Sarkhan is unbroken indeed, but we will surely break him and our other Dragon friends to the extreme. Coming with a full suite of counters at your disposal, you will have no problem waiting till turn 4 to play Caryatid with Scorn mana on standby! Once you've got your opponenent tapped out with Icefall or countered from last turn, go ahead and drop your Sarkhan Unbroken and start producing a dragon menace your opponent won't be able to deal with! For the early decks, you have a transformational sideboard, including both Circle of Flame AND Anger for those pesky Goblin and Heroic decks, just replace your ramp with removal! xD
