How many times can you use an energy card in Pokemon?

If the damage exceeds the defending Pokémon's HP and leaves them with 0 HP, it is "knocked out" (i.e. discarded along with any attached cards) and the active player takes a prize card (from their own pile) and ends their turn. During one turn, only one energy card can be played, and only one attack can be made.

Can you reuse energy cards in Pokemon?

Unless a card specifically tells you to discard Energy, don't discard any Energy from your Pokémon! Trainer cards are played by doing what they say and then putting them in your discard pile. Supporter cards are similar to Trainer cards, but you can only play one each turn.
