Expansion to the base set that introduced the Original Series and the "tribbles" side deck as well as introducing a format change to the cards that included listing card number and rarity in the lower right corner.
Special features include pre-constructed starter decks with premium cards in each and the return of ultra-rare cards inserted into booster packs (there would be an ultra-rare in each expansion from that point forward).
The set included 141 cards and was available in two pre-constructed 60-card starter decks (one Federation, one Klingon) and 11-card expansion packs.
This expansion featured Dr. McCoy as its ultra-rare as a tribute to DeForest Kelley, who had died the previous year.
