Duel Decks: Elves vs. Inventors was released on April 6, 2018 as the last set of the Duel Decks series, which had started in 2007. Duel Decks contained two 60-card ready to play decks built around two opposing themes. The decks contained only reprints that could be from any tournament legal set.

Elves vs. Inventors was also the first set with a new templating: Some wording was modified and rules and flavor text were separated by a horizontal line. This line has a smooth bottom edge in most following supplemental sets and minor products as well as in all made in Japan printings. Apart from that the line is serrated.
