Idk how he hasn't been mentioned yet but...R.A. The Rugged Man.
His verse on this song is insane.. https://www.youtube.com/watch?v=Dn4Y-NJsi3s
Check out his newest album Legends Never Die, this dude dropped off the map for 10 years then comes back and drops an album with one of best lyrical showcases I've ever seen.
