Why are there three Matzot?

The top matzah is referred to as  Kohen,  for the  Kohen  takes precedence in all matters.

The middle matzah  Levi  is broken into two at the beginning of the Seder. The smaller piece is left on the plate and is later eaten along with the  Kohen matzah in fulfillment of the mitzvah of matzah; the larger piece is put away for use as the  afikoman.

The bottom matzah,  Yisrael  is used for  korech,  so that every one of the matzot is used for the performance of a mitzvah.
