I didn't do this for EVERY letter, but the first two AtoZ "expansions" had working booster packs of 15 cards, sorted like so: 11 commons (of 100 possibilities), 3 uncommons (of 100 possibilities) and 1 rare (of 113 possibilities). Which means that every time you refresh this page, you will get a different distribution of cards! Makes a nice palate cleanse before heading into the Encyclopedia's B's. Note that Enhanced Apocalypse Rising would have been 4 special packs with set card lists, and A's Broken Links would have come in a 40-page box, so those cards aren't in the booster.
The last of the Enhanced B's... THE ENTRIES: [71] Brooks, Ensign [72] Brota [73] Bullock, Admiral [74] bunt [75] burgundy NOTES: [71] Source: "Darkling", though the text and AU icon refer to "Year of Hell" (I took the clearest I could find) [72] Sons of Mogh refer to any personnel with those words in their lore or title, including Premiere Worf, Kurn, Worf Son of Mogh, and himself. Source: "Children of Time" [73] See Valerie Archer in Enhanced Apocalypse Rising for more information on 8472 infiltrators. This one has a little more skills, and counts as an Admiral (in case Species 8472 can ever use Going to the Top). Source: "In the Flesh" [74] "Baseball personnel" are personnel that "love baseball" or actually play it. The points scored are not Baseball's 20, but Bunt's 5. The last function could be used in conjunction with Are These Truly Your Friends Brother? or to recycle a Bunt you don't want in your hand ...
