Labyrinth: Units can not access this terrain unless it has an effect which permits and entry in this field (ie: Labyrinth Tank, Wall Shadow), nor can a card be played on Labyrinth terrain.

The terrain affects the game by giving an advantage to some and harming others as the ATK and DEF and the number of movements (when face up). No monsters can ever move more than two tiles per turn. This allows movement to a diagonal tile in one turn, or simply moving two units horizontal/vertically. If the monster (including deckleader) has a movespeed advantage (via terrain or effect), can move up to two units away from its current position. Cards are unable to change position (atk/def) and move a tile in the same turn, however cards can be flipped face up manually prior to moving, as part of its move. This move can either involve flipping the card face up (if not already flipped), changing its position to attack/defense, or physically moving to another tile - either a tile adjacent to its current space. Each duelists' deck leaders start out on opposing sides, and as well as cards that are played themselves, are only allowed one move per turn. This perfect rule involves several changes, the biggest being the addition of a 7x7 grid of tiles for each play field, as opposed to the standard 5 slots for monster cards and 5 slots for spells/traps - however the rule is carried over that only 5 of your monsters and up to 5 of your spell/trap cards can be present on the field at any given time. In addition to these abilities, there are also hidden abilities which are important in the game such as the hidden card find, and extra slots in the slot machine, however these abilities are not listed and have no effect on duels themselves. Stronger monster types such as dragons gain the ability to reduce the summoning cost of their own high powered, high levelled monsters, whereas weaker decks such as the low powered fairy deck relies on a much stronger set of abilities that harm enemy creatures whilst buffing and protecting their own. Leader abilities change depending on the type of monster cards, and are often used to compliment the type of monster. There are a total of 12 ranks for deck leaders - as they rank up, they gain leader abilities. If you have ranked up a card that can not be obtained, it will retain its abilities, but can not be used as the deck leader. This also means it is possible to be hit directly even if you have monster cards out on the field.Дeck Leaders can be any monster card you have obtained, that has been levelled at least once with the ranking system.

Also, just like the Deck Leader representing you playing the cards, it also represents you when you take a direct hit - any hit on the deck leader will LP damage to you as if it was a direct hit. Each turn you are also allowed to play one card within a surrounding tile of your deck leader - provided there is no enemy units occupying the tile. However, unlike monsters, your deck leader can never order an attack. Like Monster cards, Deck Leaders are allowed one move each turn - allowing it to move one space (or two, if it has the Increased Movement bonus). Your deck leader is essentially the 'avatar' of your deck - as it represents you playing the cards on the field. Any deck you build needs to be assigned a Deck Leader. The main focus of the Perfect Rule is the deck leader system. In the intro, Simon McMooran states that the dueling rules differ from the ones that are in the present time and that they are under the 'Perfect Rule.'
