If you use Plasma Fists against a Dynamaxed Pokemon that uses Max Strike, Max Strike will become Max Lightning. I tested this on Showdown. I used the Normal Type Move Facade that turned into Max Strike once Luxray Dynamaxed. After Zeraora uses Plasma Fists, Max Strike turns into Max Lightning. Here is the replay: https://replay.pokemonshowdown.com/gen8nationaldexag-1200859599-i50pctuqoys8wbv7cojvlsc3496gkchpw
Hope this helps!
