Myth of Mythic proportions

I’d just like to highlight the fact that mythic rares are actually no more rare than a tempest rare, or mirage or any other large set. Where things have changed is that gold rares in a set like alara, M2010 and Zendikar are in face less rare. My argument is based on the following.

A standard sheet of magic cards is 121 cards.  Based on the stats for shards of alara there are 53 gold rares and 15 mythic rares. When you do the math 53 + 53 = 106 + 15 = 121.

Coincidence? I don’t think so. Basically you have the same chance of opening any one of the mythic rares that you had opening one of the normal rares in the older blocks.

What has changed is the gold rares are actually less rare, and you have a higher chance of opening one of the new fetch lands than you did opening the old ones by a factor of 2. You also don’t get as many “filler” rares in the set, which means more goodness.
