They mention that little combination right in the article about chandra. I think she is super sick! Cruel control says "yes please!" You could justify a 3/2 split in extended between jace tms and chandra fb (firebrand, it'll catch on!) if you are playing such a deck.
I'm excited to see what they did with garruk. I imagine they will notch his cmc up a little bit, considering green has zero problem ramping anyway. Possibly, something with the same cost as Sorin markov and, hopefully, a negative 2 explosive vegetation.
