That's kinda like learning to dance from a book. An actual nice MC has an aptitude for the shyt. There is a process of polishing and mentoring but no amount of teacing can make someone who lacks the MC factor into an MC.
Even if you study what other MCs do and ape their patterns, that's nowhere near the same as being an MC. Greg Nice should never step into G Rap's lane - and vice versa. We need some cats to be Biz Markie and some to be Mos Def. Their natural rhyme patterns differ and creates a broad spectrum. If there was a "way" to rap (like there is a "way" to swim the freestlye stroke) then we'd all rhyme the same. There is no "way" to rhyme besides the particular way you rhyme.
Just so you know that I'm an expert, here's an excerpt (<<<keystyle muff huggers)
(written)
Catching wreck. I mean we definitely crashing
Make sure your fukking safety belt is fastened
Atmosphere is Aspen. It's Alaskan
I have you gasping. Grasping for asprin
Channeling Johnny Cochran, wanna argue?
You better off letting Bill Clinton cigar you
I come to scar you. Honkey Tonk Man guitar you
I'm here to spar-You are not ready, are you?
