Living End is a pure graveyard combo deck that cycles/discards its whole hand of creatures to cheat them into play via the cascade-triggered mass reanimation. Tormod's Crypt proactively removes their discarded creatures before Living End resolves. The Stone Brain can permanently exile all copies of their namesake card if you find it early. Watch out for their Force of Negation countering your hate pieces, so try to play your hate pieces on curve rather than waiting.
