Base Neo format decklist. Original decklist credit goes to Jason Klaczinski from his blog jklaczpokemon.com
"With 14 free-retreating Pokémon, this deck not only easily retreats to Cleffa for a crucial Turn 1 Eeeeeeek, but also benefits from being able to play Double Gust, which functions like a Gust of Wind and Switch in one. Chaos Gym helps protect Sneasel from Energy Removal & Super Energy Removal and Energy Charge recovers lost Darkness Energy.
Tip: Try to fill your Bench and get some Pokémon Tools down before dropping Chaos Gym. (You don’t want it to hinder you more than your oppponent!)"
