input: [Revised text] Electivire pulls back one of its fists, which is surrounded by swirling energy which changes from white to light blue. It then punches the opponent, freezing it. [Justification] The repetition of "fists AND energy AND energy THAT fist" is alleviated by clauses with "which". Looking back at the episode, the shift from white to light blue is subtle and immediate, which the previous iteration didn't capture because of its clunkiness. There's no such thing as a punch without a fist, so "with the fist" is completely unnecessary. "Freezing it" is more terse and sounds more active. 215 -> 161 = -54 [Original text] 
output: Electivire pulls back one of its fists and swirling white energy forms around it and forms into a light blue energy that surrounds Electivire's fist. It then punches the opponent with the fist, causing it to freeze.
