Fast Charge - "If you go first, you may use this attack during your first turn."

I lost my coin toss, but opponent chose for me to go first. They went second, but were still able to use this to get another energy. Opponent had a Bravery Charm equipped , +50 HP.

It doesn't say "only." It can be used on any turn.
