Janine's Secret Technique.

Choose up to 2 of your Darkness Pokémon. For each of those Pokémon, search your deck for a Basic Darkness Energy card and attach it to that Pokémon. Then, shuffle your deck. If you attached any Energy to your Active Pokémon in this way, that Pokémon is now Poisoned.

You may play only 1 Supporter card during your turn.
