Cards (KHCOM)

Cards are used by Sora to fight and proceed through Castle Oblivion in Kingdom Hearts: Chain of Memories. New cards are either given to Sora through plot events, found in the environment, bought in Moogle rooms, or won in Battles. The attack and magic cards, once used, can be restored by charging. Furthermore, they can be stocked to make a more powerful combo.

Battle Cards
These Cards are used during battle.

Attack Cards each contain one strike with the Keyblade, and are colored bright red.

Magic Cards either let Sora use a spell or use a summon, and are colored bright blue.

Item Cards restore attack and magic cards after use, and are colored bright green.

Enemy Cards enable a status affect, which can change Card Value, increase speed, and make Sora invulnerable to certain elements. They are colored black.

Friend Cards appear randomly during battles, and when picked up and used, Sora can call for the aid of a party member.

Gimmick Cards only appear during Boss Battles. These cards are colored Green, like item Cards, and Have the Mickey Mouse insignia on the card. When used, the colors on the screen inverse, and the flow of battle changes in Sora's favor.

Map Cards
These Cards are used Outside the battlefield, in a room or Castle Oblivion.

Map Cards allow Sora to open doors that lead into unexplored rooms, or can be used to change a room that he has already opened. (Example; If you have already opened up a Calm Bounty room and taken the treasure, you can leave the room and strike the door again to change it to a new Calm Bounty Room, granted you have the card.) Certain Map Cards can trigger events that advance the plot.

World Cards allow Sora to proceed to the next floor in Castle Oblivion. The only exception is at the top floor, where Sora proceeds without a card into Castle Oblivion itself.

Basics
You only need to use cards to attack, use magic, use items, summon friends, or add an status effect to Sora. Moving, dodging, and jumping are outside of card use.

Decks
You can create Decks of cards to use in Battle using CP. Each card has a CP cost, except for those that appear randomly in battle. If you exceed the Maximum CP, your Deck cannot be used.

Sleights
Sleights can be used when stocking three cards together. You must stock a certain combination of Cards, depending on Card type, Card Name, and Card Value. All cards except Enemy Cards can be stocked during battle.

Card Value
All cards used in battle (with the exception of Enemy Cards) have a small number in the corner, which is the card's Card Value. The higher the card value, the more versatile the card is in breaking other cards, but the more CP it costs to have. When Sleights are involved, the added Card Value of the Sleight becomes the total card value, meaning if you stocked three 9's, the total Card Value would be 27, the most powerful aside from 0. 0 Cards are the most powerful, and can break any card that comes before it, but can be broken by any card that comes after it. 0 Can still break Sleights.
