This Gyarados ex deck is all about turning a tiny Magikarp into a raging powerhouse! With the right setup, Gyarados ex can sweep through your opponent's Pokémon with huge damage from its Rampaging Whirlpool attack.

Start by placing your Magikarp in your Bench, with the help of Professor’s Research or Poké Ball if it isn't in your starting hand. Use Misty to accelerate the Energy on your Gyaradox ex.

While Gyarados powers up in the Bench, Druddigon and Kangaskhan can hold down the fort in the Active spot with solid health pools, which pairs perfect with Rocky Helmet to make opponents regret every hit.
