In this frenzy you'll find new Pokémon LV.X, Trainer cards that power up when played together, and the dramatic entrance of some of the most popular Pokémon ever! The time has come to enter the storm, and witness this awe-inspiring spectacle first-hand!



Raging Sea Theme Deck
When you play with the Raging Sea theme deck, crashing waves mean the tide is turning in your favor! The ever-powerful Gyarados thrives on causing serious disruption in your opponent's forces. Its Dragon Beat attack gives you the chance to discard an Energy card from each of your opponent's Pokémon—leaving these Pokémon low on resources and running for higher ground! And watch as Sceptile becomes your favorite new ally with its Slice Drain attack—it does big damage and then heals itself with every impact! Unleash the Raging Sea theme deck and you'll ride out the storm on top!

Dark Rampage Theme Deck
Prepare for some serious crushing power when you play with the Dark Rampage theme deck. Each time your opponent uses a Poké-Power, the Armor Pokémon Tyranitar's Darkness Drive Poké-Body lets you attach a Darkness Energy card to power up Tyranitar's Grind attack for an additional 20 damage! Then, go for a quick finish by bringing in Staraptor. Its Clutch attack will grab onto the Defending Pokémon, making it unable to avoid the next big hit! No matter how you play the Dark Rampage theme deck, you're putting on the hurt each turn and never letting up!
Each theme deck contains 1 complete 60-card deck. Many of the cards exist in multiples to provide a more enjoyable playing experience.
