Challenges ring out, Pokémon duel, and the battle for Unova enters the next chapter in the Pokémon TCG: Black & White—Plasma Blast expansion! With Virizion-EX by your side, you must lead the counterattack against the failing forces of Team Plasma as they mount their last stand behind the twinned might of Team Plasma Dialga-EX and Palkia-EX! Victory is within your grasp, when suddenly you face your greatest test...the mighty and mysterious Genesect-EX takes the battlefield, supported by devastating ACE SPEC cards that give it additional attacks! Trainers, it's time to break the ice!
Plasma Blast and the Japanese equivalent Megalo Cannon feature the debut of Genesect in the Pokémon Trading Card Game, as well as Team Plasma, their Pokémon, and for the first time since their debut in Plasma Storm, cards designed to specifically counter Team Plasma. Plasma Blast contains 105 cards, while Megalo Cannon contains 86 cards, including Shiny Secret cards. It was released on March 15, 2013 in Japan accompanied by the Blastoise + Kyurem-EX Combo Deck, and on August 14, 2013 in English.
Plasma Blast is the third set of the BW era to feature Fossils, the first two being Noble Victories and Dark Explorers. Archen and Tirtouga are given their second cards, while Lileep is given its first printing as a Restored Pokémon. Plume Fossil and Cover Fossil are reprinted, and a new fossil Trainer card, Root Fossil Lileep is included in preference to the previous Root Fossil in order to prevent confusion over how the card should work. The expansion is the first to feature new Technical Machine-like Pokémon Tool cards with attacks present on them.
In order to help defend against Team Plasma's onslaught, Unova champion Iris is present alongside Caitlin, a member of the Unova Elite Four. Six Pokémon-EX are included: Virizion-EX, Jirachi-EX, Kyurem-EX and Team Plasma's Genesect-EX, Dialga-EX, and Palkia-EX. Many of the Pokémon present are not from Generation V, but instead are Pokémon from older Generations, some of which not featured in the Card Game since the Diamond & Pearl Series.
The Prerelease promo is Porygon-Z, a reprint with new artwork of the same Pokémon in the expansion, which was also given to those who purchased a booster box of Megalo Cannon in stores in Japan.
