Grafdiggers cage about to EXPLODE?

CoCo as the engine of every creature based deck (Abzan company, elves, slivers...), best combo on the form of Kiki Chord, Dredge on its way to a resurrection with SoI aditions, and now Nahiri rebirthing control. Copies are drying up on TCG. No way this card does not reach +10$ in a couple weeks... Pick your copies!
