Janine's Secret Art - 060/064 (060/064) [SV6a: Night Wanderer]

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 Energy to your Active Pokémon in this way, it is now Poisoned.
