Any Clue What Old School Hip Hop Artist(s) This May Be?

This is a line "Pound for pound the number one top contender the hell with ????? give me the ????? I'll defend her"

This is a line "Cool and flexibly hard, be on your guard or you'll be in a graveyard"

This is a line "????? like a mountain, his rhymes flow like water from a fountain"

This is the chorus "Here we go, here we go, no time to flow"

This could all be from different artists and different songs. I am 99.9% sure that the lines are NOT from the same song. For some reason DJ Magic Mike and MC Madness come to mind from the album "Ain't No Doubt About It" Also, D-Nice comes to mind, but what are the names of the songs?? Any guesses are very much appreciated

Tim Dog also comes to mind
