Both players do these things to set up for a game:
A. Shuffle your deck.
B. Take 5 cards from the top of your deck, but don't look at them. Put them in a row in front of you face down. These face-down cards become your shields.
C. Draw 5 cards from the top of your deck.
D. Decide who goes first.
1.1 How to Win
Attack your opponent with your creatures. Each time one of your creatures attacks your opponent and isn't blocked, it breaks a shield. When your opponent has no shields left, have one of your creatures attack him one more time to win!
2. Turn Order
2.1 Start your turn.
Don't do anything during this step of your turn if you don't have any "tapped" creatures in the battle zone or tapped cards in your mana zone. Tapped cards are cards that you turned sideways on a previous turn to show you used them for something. You won't usually have any tapped cards until you have already played a couple turns of the game.
If you have any tapped cards, untap them now to show that you get to use those cards again this turn.
2.2 Draw a card.
Only the person who plays first skips drawing a card on his first turn. Drawing a card means taking it from the top of your deck and putting it into your hand.
As soon as you draw the last card of your deck, you lose.
2.3 Put 1 card into your mana zone.
You can put only 1 card (of any type) into your mana zone from your hand each turn, unless a spell or effect allows you to put more. You don't have to put a card into your mana zone each turn if you don't want to. There's no limit to the number of cards you can have in your mana zone.
Put the card into your mana zone upside down so you can read its mana number. Cards in your mana zone can get mana for you. Mana is like money. You use it to pay for creatures and spells. Cards in your mana zone can't do anything but give you mana. Ignore all the text on them except for their mana numbers. Some abilites allow a card to be summoned from mana zone, but the cards states that clearly then.
2.4 Summon creatures and cast spells.
If you want to, you can summon any number of creatures and cast any number of spells during this step. You can do these things in any order.
2.4.1 How to cast a spell
Choose a spell from your hand. The cost for a spell is in the upper left corner. If you can't pay the cost, you can't cast the spell. You pay a spell's cost by tapping cards in your mana zone for mana. At least 1 of the mana must be the same civilization as the spell.
Example: To cast a nature spell that costs 4, tap at least 1 nature card in your mana zone. The other 3 cards you tap may be of any civilization.
After you pay for a spell, do what it says. If you can't do everything it says, that's okay. Just do as much as you can. Then put the spell into your graveyard. Keep your graveyard face up next to your deck.
2.4.2 How to summon a creature
Choose a creature from your hand. The cost for a creature is in the upper left corner. If you can't pay the cost, you can't summon the creature. You pay a creature's cost by tapping cards in your mana zone for mana. At least 1 of the mana must be the same civilization as the creature.
After you pay for a creature, put it into the battle zone. There's no limit to the number of creatures you can have in the battle zone.
Creatures can't attack on the turn you put them into the battle zone because they have summoning sickness, if not stated otherwise (speed attackers and evolutions). They will be able to attack on your next turn.
2.4.3 How to summon an evolution creature
An evolution creature is a special kind of creature that will be introduced in the first Duel Masters expansion. Summoning an evolution creature works just like summoning a regular creature except you can summon an evolution creature only when you have the correct race of creature already in the battle zone. The evolution creature tells you what race of creature you need to have.
Once you summon an evolution creature, put it on top of the creature it "evolves" from. Leave that creature underneath the evolution creature, but ignore it. Only the evolution creature's name, abilities, color, and power matter. There's no limit to the number of evolution creatures you can put on top of each other.
Evolution creatures don't get summoning sickness even if the creature they evolved from had summoning sickness, so you can attack immediately after you put them into the battle zone.
You can't ever evolve another player's creature, even in multiplayer games. If an evolution creature is moved from the battle zone to anywhere else, then the whole pile moves, not just the evolution creature on top.
As long as the evolution creature is in play, it and the card it evolved from count as only one card. As soon as the pile ends up somewhere other than the battle zone, they are separate cards again. So if a spell makes you put your evolution creature into your mana zone, you get that many separate cards in your mana zone.
You can attack with your creatures in the battle zone. You can't attack with creatures you just put into the battle zone this turn, because they have summoning sickness. As many of your creatures as you want can attack each turn. Choose one, have it attack, choose another one, have that one attack, and so on.
Tap a creature you want to attack with and say what you want it to attack. It can attack your opponent or one of his tapped creatures in the battle zone. When a creature taps to attack, you don't have to tap cards in your mana zone, too. Once you've paid to summon a creature, you don't have to pay to have it attack.
2.5.1 Attacking your opponent
When one of your creatures attacks your opponent and it isn't blocked, it "breaks" one of your opponent's shields. That means you choose one of those shields. Your opponent then picks up that shield and puts it into his hand.
Some creatures can break more than one shield when they hit your opponent. They say "double breaker." If your opponent has fewer shields than your attacking creature can break, your creature doesn't knock out your opponent, just however many shields are left.
When your opponent has no shields left, if one of your creatures attacks him one more time, you win the game.
2.5.2 Attacking a tapped creature
When one of your creatures attacks one of your opponent's tapped creatures in the battle zone and it isn't blocked, then the creatures battle.
Each creature has a power number in its lower left corner. The creature with the higher power wins the battle. The loser's owner puts it into his graveyard. If the creatures have the same power number, then both creatures go to their owners' graveyards. Some creatures have "+" after their power. This means that the creature's power can get bigger because of something in the creature's text box. Make sure to read what it says!
2.5.3 Attack effects
Some of the creatures in upcoming sets have extra effects when they attack. When you want one of your creatures to attack, choose which creature you want to attack with, tap it, and choose what it's attacking. Then do any effects that happen because that creature is attacking. After that, your opponent can choose blockers.
2.5.4 Blocking an attack
Only creatures with the "blocker" ability can get in the way to stop creatures from attacking what the attacking player wants them to attack.
You can use one of your "blocker" creatures to stop any attack. When your creature blocks, you have to tap it, so it can block only if it's untapped. Summoning sickness doesn't stop a creature from being able to block. When a creature blocks, it battles the attacking creature. The attacking creature can't attack what it was going to attack (your opponent or another creature), because it must now battle the blocker.
The creature with the higher power wins the battle. The other creature's owner puts it into his graveyard. If the creatures have the same power, then both creatures go to their owners' graveyards. Some creatures have "+" after their power. This means the creature's power can get bigger because of something in the creature's text box. Make sure to read what it says! There are also some other effects abilities that you might want to consider before attacking.
2.5.5 Order of attack steps
What happens first can sometimes matter during an attack. The following rules talk about the order in which things happen.
When you tap your creature to attack your opponent, do any effects that say they happen "when this creature attacks." Then, if your opponent doesn't block, follow any other instructions on your creature that apply. Then break shields (or win if no shields are left).
When two creatures battle, first follow any instructions on your creature that apply. Then your opponent follows any instructions on his creature that apply. Then compare the powers of the two creatures. If one creature's power is lower, put it in its owner's graveyard. If the powers are the same, put both creatures in their owners' graveyards. Then follow any card instructions that apply after the battle.
2.6 End your turn.
Tell your opponent you're done. Now it's your opponent's turn! Continue taking turns until one of you wins.
You win if your opponent has no shields and you attack him or if your opponent draws his last deck card.
