In theory (although not in practice, because box distribution isn't truly random), a booster box could contain zero mythics and all bulk rares, or it could contain a complete set of foil mythics

Marionette Apprentice does a very similar job at just 2 mana
The uncommon Mentor and Bonder disproportionately reward Flying, Vigilance, Trample, and Menace (since each gets both)
You can also spot Elrond and the Elven Cloak here, too
