What does a t2 living end accomplish? Kill a creature and put a 4/4 dork and maybe a 3/4 into play? That or the living end player has to have the nuts draw of land, land, cascade, ssg and one cycler, drawing multiple street wraiths in the process or more ssgs and cyclers. Truly a christmasland scenario. (Maybe I'm missing something.)
Do you mean Goryo's Vengeance or Through the Breach?
I think he means the deck as a whole.
