The Premiere set contained nine different card types, but soon others began to appear. What was the second card type to be added to the original nine?

The nine original card types were Artifact, Dilemma, Equipment, Event, Interrupt, Mission, Outpost, Personnel, and Ship. The Alternate Universe expansion added the first new card type, Doorway, and Q-Continuum had the second new card type: Station. Although stations became a subtype of the Facility card type in the Deep Space Nine rules, there was no Facility card type when Station cards appeared and they were listed as a new card type in the Rules Supplement. Q-icon cards were never considered a new card type; in fact, the Rules Supplement specifically stated that the cards were interrupts, events, and dilemmas. (Many people said Objectives; however, First Contact also introduced Time Locations, so neither could be considered to come before the other.)

Name the second version of the Jean-Luc Picard persona to be published.

The first version of the Jean-Luc Picard persona was, of course, Jean-Luc Picard (Premiere), even though personas had not yet been defined as such. When they were defined – in Q-Continuum – that set included the second version: Galen. Although Lt. (j.g.) Picard appeared in Alternate Universe, he isn't (and wasn't) a version of "the Jean-Luc Picard persona." He's the only version of the Lt. (j.g.) Picard persona. Locutus of Borg, named by many entries, was in the Fajo Collection.

Name the second dual-personnel card to appear.

The first was Sisters of Duras, in The Fajo Collection. The second didn't show up until Deep Space Nine – Jake and Nog. (Quite a few people confused dual-personnel with dual-affiliation, naming Stefan de Seve.)

In which product did the second Ferengi-affiliation card appear?

The card itself was the answer to the previous question, Jake and Nog (they're Federation/Ferengi), so the product was Deep Space Nine. The first Ferengi-affiliation card was another dual-affiliation card, the preview Quark Son of Keldar in First Anthology. Ferengi Trading Post was in Starter Deck II.

What was the second Star Trek CCG product to have one or more dual-affiliation cards?

Dual-affiliation cards made their debut in Alternate Universe, with two Romulan/Federation personnel, Major Rakal and Stefan DeSeve. The next product to have any was not, as many believed, The Fajo Collection or Deep Space Nine; there were in fact two dual-affiliation personnel in First Anthology, Quark Son of Keldar (Klg/Fer) and Garak (Car/NA).
