There are plenty of great reasons to check out the Pokémon
TCG: Sword & Shield—Evolving Skies expansion, including the
many Eevee Evolutions, powerful Pokémon V and VMAX, and more. Picking up a
Duraludon promo card from GameStop with a $15 or more Pokémon TCG purchase is
another reason to fly high with the latest expansion. Add Duraludon to
your deck and show your mettle with the Metal-type Pokémon’s two sturdy
attacks: Metal Claw and Steel Beam.
Purchases can be made online or in-store, but the Duraludon promo card is only available while supplies last.
