Panini Games has revealed the first follow-up set for its new Meta-X Justice League Trading Card Game. The Green Lantern Booster Set will release in December.

In an announcement at SDCC, Panini confirmed that the first expansion to support the Justice League set would feature the characters and villains that surround the ring-wielding hero Green Lantern.  Graphics promoting the new set depict Lanterns of other colors, as revealed in the Blackest Night storyline.  Green Lantern will be available only in booster packs.

Panini was previewing the Justice League set, which will be available both in starter decks and booster packs, at the show.  Announced earlier this year, the new trading card game is scheduled to release on August 4 (see “Details on ‘Justice League TCG’”).
