The Sabrina's Sleepy Time 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.
No, this deck isn't boring to play, but it sure will put your opponent's Pokémon to Sleep! The idea here it to just keep putting your opponent's Pokémon to Sleep with Jigglypuff, Snorlax, Drowzee, and the rest of the deck's Pokémon. With your opponent's Pokémon Asleep half the time, just keep damaging them until you win!
If you can get Wigglytuff out, you can use Do the Wave to finish off a lot of Pokémon. Challenge! makes it easy to fill your Bench and take advantage of Wigglytuff's attack. Use the Full Heal Trainer cards and Full Heal Energy cards to wake up your own Pokémon if they make themselves Asleep too often. Sabrina's ESP gives you an extra chance to make really important coin flips (and this deck does a lot of coin flipping).
