Mic and alive work because of the distinct I sound and the syllables around them. End rhymes are not just the last word of a bar, it's the last rhyming phrase. That basically means its not limited to only one word. You can overlook one syllable words if they blend correctly in the multi; not every word has I rhyme exactly.
It's a lot to learn haha, it came to me over time watching the forum. Rhyming isn't everything but stringing together an impressive multi is a nice thing to have in your repertoire.
