Flourish / Rebellion Theme Decks
Sweet victory is yours with the fast-moving Flourish deck! Silcoon becomes the powerful Beautifly in the blink of an eye, while swarms of Fire and Grass Pokémon catapult into action. The amazing Shaymin enables you to dish out damage to your opponent's Pokémon with Energy Blow, while keeping your team in top condition by removing damage counters with Aromatherapy. When you don't have time to mess around, go ahead and win with a Flourish!
What do you get when you team up Fighting and Psychic Pokémon? You get a hard-hitting team with some tricks up its sleeve! The mighty Giratina keeps you safe with its Dragonbreath as Mismagius and Dugtrio use their sneaky traps to catch your opponents off guard. Then, unleash Gardevoir and its double-barreled Energy Burst attack. The more Energy in the field, the stronger it gets! With your strength and savvy, you'll lead your Rebellion to supremacy!
