MURDERFIA: REDUX: (VERY END)

I see the plan behind your call to rap.
You hope to lure me into a trap.
After all, today all my words must be formal.
And rapping tends to turn sentences abnormal.

But your hopes for victory are merely a dream.
I have the skills to exploit the flaw in your scheme.
If I hold to one simple rule, I will be fine.
I need only start a new sentence on each line.

In fact, I have a way to raise the stakes of this game.
If I must follow the rules, it seems fair that you do the same.
You must forfeit should you fail to speak as I ask.
Of course, I doubt you will be up to the task.

You must favour British spelling. You may not use contractions.
And we cannot forget the most important limit on your actions.
Your punctuation and spelling must always be sublime.
Accept my challenge, and it will be grammar time.
