I have Hidden Legends Electrode and use "Mass Destruction" to knock out Electode and the defending Pokémon. If I have only one prize left and my opponent has more, but I have no bench and my opponent has a bench, do I still win?
No, in this situation it would go to Sudden Death. However, if the opponent did not have any Pokémon on their bench, the Electrode player would have two win conditions vs. one, and would therefore win the game.
