I think Deck has a problem that he has always been a type of an underground rapper. He has eveything what a mainsteam arist should have - flow, lyrics, style - but he's never been like even Meth.
I don't know what y'all think about Deck's discography, but he's never released a weak album! Of course he has better and worse shit.
"I know your deeds, that you are neither cold nor hot. I wish you were either one or the other! So, because you are lukewarm—neither hot nor cold—I am about to spit you out of my mouth" (Rev. 3:15-16)
