Black Market OPs

I love the new items especially Deadman's Plate, fit's volibear perfectly and I have seen amazing results using this item as jungle devourer volibear its insane having 480 movespeed going catching onto someone with that [75% 1second slow + I believe 200ad on hit] its insane lol, not to mention I max Q second after W and get righteous glory

GO VOLIBEARR RUSHING INTO BATTLE! Insanely fast! Try it out! Anyone have any other builds or champions that benefit interestingly from purchases out of the Black Market?
