gyrados pokemon card X & Y Ancient Origins Single Rare Gyarados #20 Evolves from Magikarp Type Pokémon Japanese - Dark Gyarados

Without further knowledge its a safe bet to set them as the framework for the deck given their successful track record

Cards from every set on the platform are legal in the format, including cards from supplementary sets like Jumpstart

If you have any suggestions for cards to include, or other directions to take this Commander entirely, let me know in the comments.
