Retreat/Ramp Nasus

The Nasus list that made t4 in China was focused heavily on ramping and WYPM effects, utilizing 3 copies apiece of Find Your Center, Retreat, and Temporal Breach alongside 9 turn one plays to quickly ramp into its lategame (3 TTW, 2 tasty faefolk and 1 whiteflame protector). I am.... very intrigued by this line of thinking and I want to try building something of my own. I understand why the builder of this deck wanted Tasty in there (accelerate good) but I am not sure I feel similarly about that card. What I do agree with is that Nasus provides you with a mana advantage when playing big units, so you don't necessarily *need* Heron for that, and Heron can sometimes feel like overkill in Nasus lists.
