Nasus, Curator of the Sands (2/2/2 Heron/Vilemaw/Watcher)

I am losing my mind trying to decide between 7+ cost units for triggering Nasus. Can you tell? Lets try this, why not. 6 feels like an overall good number of 7+ cost units (plus obviously access to Nasus CC), Heron helps with the power cost issues on TTW and Vilemaw, and those cards help with the Heron issue of "I have discounts and nothing to do with them." so maybe this is just the real actual way to go.
