Including Mythic, with the caveat that I don't actually *have* them all::

  1 each of 21 mythic      21 cards
  1 each of 57 rares       57 cards
  2 each of 95 uncommons  190 cards
  4 each of 79 commons    316 cards
			  584 cards total

That's about a 1 : 2.5 : 4 ratio, grouping Mythic and Rare together.

Leaving out Mythic:

  1 each of 57 rares       57 cards
  2 each of 95 uncommons  190 cards
  4 each of 79 commons    316 cards
			  563 cards total

That's about a 1 : 3.3 : 5.5 ratio.

Leaving out Rares:

  2 each of 95 uncommons  190 cards
  4 each of 79 commons    316 cards
			  506 cards total

That's about a 2 : 3 ratio.

Going up to five of each Common:

  2 each of 95 uncommons  190 cards
  5 each of 79 commons    395 cards
			  585 cards total

That's about a 1 : 2 ratio.
