[Very good, very good. The doors close behind them, but the train doesn't take off quite yet. The intercom does come on, however.]

You will use two Pokémon each against your opponents. If your Pokémon uses a consumable item, the item will be returned to you after the battle. If you defeat your opponent, you will progress to the next car to continue your challenge. Breaks are permitted after every seventh battle; you may come and go as you please, then. When you reach the last car, you will be challenged by the Subway Bosses.

Please prepare yourselves while the hologram program starts up. Thank you.

[That sounds kind of familiar.]
