From Bulbapedia, the community-driven Pokémon encyclopedia.
The Stormshaper Theme Deck from the Arceus expansion of the Pokémon Trading Card Game predominantly focuses on and type Pokémon. Like other Theme Decks, Stormshaper also includes a rulebook, damage counters, status counters, a custom coin, single-player mat and card list.
Shocks are in store for your opponents with this Lightning Arceus-led deck. Vary your Active Pokémon and attacks at breakneck speed with the Alpha Pokémon's Lightning Turn attack and, as if that weren't enough, use the Pokémon Tool Expert Belt to both boost your Pokémon HP and increase the damage... as well as the devastation of your attacks! But beware, pitfalls await the unwary Trainer who allows a Pokémon to be Knocked Out while using the Expert Belt... so shape your storms carefully!
The Non-Holofoil versions of Luxray and Swalot are exclusive to this deck.
