From Bulbapedia, the community-driven Pokémon encyclopedia.
The Fire Extinguisher Deck is a type deck found in the Gym Heroes Strategy Guide. The deck is classified as one of the easy-to-build decks, containing more common cards and less strategy than advanced decks.
"Fire Extinguisher" will put out your opponent's Energy faster then you can say Fire! Use Super Energy Removal and Energy Removal whenever you draw them to Knock Out your opponent's Energy. But the real secret to this deck is using Blaine's Charmander and Misty's Poliwhirl to keep removing Energy from your opponent's Pokémon every turn.
Misty's Tentacool will dampen your opponent's spirits even more because its Crystal Beam attack can keep your opponent from attaching an Energy on his or her turn. With you opponent so low on Energy, all you have to do is attack until you score six Knock Outs, and the game is yours!
