Basic Pokémon are Pokémon that haven’t been evolved yet. You can see if your Pokémon is a basic or not by looking at the top left corner of the Pokémon card. Your Active Pokémon should be placed on the left side of your deck. Your Active Pokémon will be the Pokémon used for attacking your opponent’s Pokémon. If you don’t have a Basic Pokémon in your deck, show your hand to your opponent and shovel it back in your deck. Draw another seven cards. If the same thing happened again, repeat. Each time you do this process, your opponent gets one extra card (Also known as a ‘Mulligan’).
Your Bench can only hold up to five Basic Pokémon.
