Pokémon Trading Card Game

Introduction

Mason Laboratory

"Oh! Why the rush, <player>? What? You want to learn how to play the Pokémon Trading Card Game? So you, too, finally want to start playing the card game. Well, dueling is more fun than just collecting cards! First, you should try playing with a practice deck. Here, I'll give you this deck. And now you need an opponent... Hey, Sam! Play with him for a while!"

"OK! Let's give it a try!"

"Hey! <player>! Hurry and come here!"

"First, ask Sam the basics of the game."

"They say actions speak louder than words, so let's play a game. Since this is your first time, just try to learn the basic steps. I'll be coaching you, so follow my advice. If you don't do as I say, we won't be able to proceed. It might be easier if you read the Pokémon Trading Card Game instruction booklet while we play. OK then, let's start your practice game!"

Practice duel

Mason Laboratory

"Draw 7 cards, and get ready for the battle! Choose your Active Pokémon. You can only choose Basic Pokémon as your Active Pokémon, so you can choose either Goldeen or Staryu. For our practice duel, choose Goldeen."

"Next, put your Pokémon on your Bench. You can switch Benched Pokémon with your Active Pokémon. Again, only Basic Pokémon can be placed on your Bench. Choose Staryu from your hand and put it there."

"When you have no Pokémon to put on your Bench, press the B button to finish."

"To use the Attack command, you need to attach Energy cards to your Pokémon. Choose cards from the menu, and select a Water Energy card. Next, choose your Active Pokémon, Goldeen, and press the A button. Then, the Water Energy card will be attached to Goldeen. Finally, attack your opponent by selecting an attack command. Choose Attack from the menu, and select Horn Attack. Now, let's play the game!"

"Your Goldeen's gonna get knocked out. Let's evolve it! Choose Seaking from your hand and attach it to Goldeen to evolve it. Its HP increases from 40 to 70. Your Seaking doesn't have enough Energy to use Waterfall. You need to attach a Psychic Energy card to Seaking. means any Energy card. Now you can use Waterfall. Keep the Water Energy for other Pokémon. Now let's attack your opponent with Seaking's Waterfall! Now, let's play the game!"

"Seaking's got enough Energy, so you don't need to attach any more. Attach Energy cards to your Benched Pokémon to get them ready for battle. Attach a Water Energy card to your Benched Staryu. Next, select the Attack command. Machop has 10 HP left. Seaking's Horn Attack will be enough to knock out Machop. Now, choose Seaking's Horn Attack. Now Machop's HP is 0 and it is knocked out. When you knock out the defending Pokémon, you can pick up a prize. Now, let's play the game!"

"When all your Pokémon are knocked out and there are no Pokémon on your Bench, you lose the game. Put Drowzee, the Basic Pokémon you just drew, on your Bench. Attach a Water Energy card to Drowzee to get it ready to attack. Choose your Active Seaking and attack your opponent with Waterfall. Now, let's play the game!"

"Choose a Benched Pokémon to replace your knocked out Pokémon. You now have Drowzee and Staryu on your Bench. Choose Staryu as the Active Pokémon for this practice duel. Here, press Select to check Pokémon data. It is important to know your cards and the status of your Pokémon. Now, let's play the game!"

"Staryu evolves into Starmie! Let's get Staryu ready to use Starmie's Attack command when it evolves into Statmie. Choose the Water Energy card from your hand and attach it to Staryu. Attack your opponent with Staryu's Slap. Now, let's play the game!"

"Now, recover Staryu with a Trainer card. Choose Potion from your hand. Now let's get ready to evolve it to Starmie. Also, attach a Water Energy card to Staryu. Attack your opponent with Staryu's Slap to end your turn. Now, let's play the game!"

"Now you have finally drawn a Starmie card! Choose Starmie from your hand and use it to evolve Staryu. You've already attached enough Energy to use Star Freeze. Attack your opponent with Starmie's Star Freeze. Now, let's play the game!"

"Now Machop has only 10 HP left. Let's finish the battle! Attack with Starmie's Star Freeze. You've knocked out your opponent! Pick up the last prize. <player> is the winner! Now, let's play the game!"

• Not following instruction

(choosing between Pokémon cards) "Choose <card> for this practice, OK?"

(other times) "This is practice mode, so please follow my guidance. Do it again."

• After resetting turn

"Do you need to practice again?"

"Basically, this is how the Pokémon Trading Card Game is played: it's a game in which you try to knock out as many of your opponent's Pokémon as there are prizes. That's the gist of it... If you don't understand something, talk to Sam. It might be helpful to practice again, too. This time was just practice, so I had you follow everything I said, but there are other styles of play. So try them out by choosing Normal Duel."

"Now then, let's build your deck. Did you bring your cards?"

"Hmm... Let me add some of my own cards to yours! Now, <player>, what kind of deck do you want?"

"OK, a <deck name>! Here are the remaining cards!"

"You should duel with many different people. Why don't you go to one of the Card Clubs. There are many people playing at the Clubs. Collect new cards and try building a new deck!"

• If spoken to again

"Gathering information is important if you wish to inherit the legendary Pokémon cards! Listen to what people have to say and read the books on the bookshelves. If I have any information, I'll send you an E-mail, so check the PC every so often to read your mail!"
