(Prism star) rule

You can’t have more than 1 card with the same name in your deck. If a card would go to the discard pile, put it in the Lost Zone instead.

This card provides Colorless Energy. 

While this card is attached to a Stage 2 Pokémon, it provides every type of Energy but provides only 1 Energy at a time. If you have 3 or more Stage 2 Pokémon in play, it provides every type of Energy but provides 4 Energy at a time.
