Let's be real for a second. Most people play Kingdom Hearts Re:Chain of Memories for about three hours, get stuck on a boss, and then just watch the cutscenes on YouTube. I get it. The transition from the fluid action of the first game to a card-based combat system feels like hitting a brick wall at sixty miles per hour. But here is the thing: once you actually "get" the deck building, this is arguably the most broken, exploitable, and satisfying game in the entire series. This Kingdom Hearts Re Chain of Memories guide isn't going to give you a lecture on the "spirit of the cards." Instead, we’re going to talk about how to manipulate the RNG, build a deck that makes Marluxia look like a joke, and finally understand what those numbers actually mean.
Stop Playing It Like an Action Game
The biggest mistake? Treating this like Kingdom Hearts 1. It looks like a hack-and-slash. It sounds like a hack-and-slash. It is absolutely not a hack-and-slash. If you run up to a Shadow and just mash the X button, you are going to get Card Broken.
When your card gets broken, you're stunned. You're vulnerable. It's a bad time.
Every single interaction in this game is a math equation. If you play a 5 and the enemy plays a 6, they win. You lose. It’s that simple. To survive, you need to stop looking at Sora and start looking at the bottom right corner of your screen. Honestly, the actual character models are secondary to the deck interface. You’re playing a high-speed game of War, and if you aren't paying attention to the values, you’re just guessing.
The Magic of Sleights (and Why You’re Ignoring Them)
Most players hoard their cards because they’re afraid of the "reloading" penalty. When you use a Sleight—stocking three cards together by hitting Triangle—you lose the first card in that stack for the rest of the fight. That sounds scary. It feels like you’re shrinking your resources.
Do it anyway.

Sleights are the only way to play. Specifically, you need to hunt for the Sonic Blade and Lethal Frame sleights. Lethal Frame is basically a "win button." You stop time, Sora zips around, and the boss loses a health bar while they can’t even move. If you fill your deck with the right cards to spam Lethal Frame, you can beat almost every boss in the game without taking a single hit.
How to Build a Sleight-Heavy Deck
Don't just throw your highest numbers in a pile. That’s amateur hour. You want to organize your deck so that every time you mash Triangle, a Sleight comes out.
- Group by value: If you need a total value of 20-23 for a specific move, put those three cards right next to each other.
- The Reload Trick: Put your "disposable" cards (the ones that disappear after a Sleight) at the front.
- Premium Cards: Use these only as the second or third card in a Sleight. Since the first card disappears anyway, using a Premium card in the second or third slot lets you keep it for the rest of the fight without the high CP cost.
The Zero Card: Your Get Out of Jail Free Card
You need at least three 0 cards at the very end of your deck. This is non-negotiable.
A 0 card is unique. If you play it after an enemy plays a card, it breaks anything. It doesn't matter if the boss just played a triple-stacked Sleight with a value of 27; your 0 will cancel it instantly. However, if you lead with a 0, the enemy can break it with literally anything.
Keep them at the back of the deck. When you hear the boss start a big, flashy move, shortcut to your 0s and shut them down. It’s the ultimate disrespect.

Leveling Up: What to Pick?
Every time Sora levels up, you get a choice: HP, CP (Card Points), or a New Sleight.
Never pick HP. Okay, maybe pick it once or twice if you’re really struggling, but CP is king. CP determines how many powerful cards you can fit in your deck. More CP means more 9s, more 0s, and more Sleights. If you have enough CP to build a deck full of "Lethal Frame" setups, you don't need HP because you’re never going to get hit.
Whenever a New Sleight is available, take it immediately. You can grind for CP later, but Sleights are gated by level and are the primary way you progress your "power" in the mid-game.
Enemy Cards: The Secret Sauce
Most people forget the enemy cards exist because they're tucked away in a separate menu. Big mistake.
The Jafar card is the MVP of the early game. It prevents enemies from breaking your attack cards for twenty hits. That’s huge. Then there’s Maleficent, which boosts your attack power but slows down your reload. For boss fights, these are the marginal gains that prevent frustration.

If you’re farming for these, remember that the last enemy you kill in a room is the one most likely to drop their card. If you want a specific card, leave that heartless for last. It's a grind, but it’s worth it.
Map Cards and Room Synthesis
Walking through doors in Re:Chain of Memories isn't just about moving forward; it’s about managing your resources. You’ll get "Map Cards" after every battle. These have different colors and effects.
- Red Cards: These change the number or strength of enemies. Use "Teeming Darkness" if you want to farm experience.
- Green Cards: These affect your deck or status.
- Blue Cards: These change the room environment, like adding save points or shops.
Always keep a "Joker" card (the multi-colored ones) in your inventory. Some doors have incredibly specific requirements, like needing a total card value of 50+. A Joker card fulfills any door requirement instantly. Don’t waste it on a random hallway; save it for the "Key to Rewards" rooms.
The Riku Side of the Story
Once you finish Sora’s story, you unlock "Reverse/Rebirth." This is Riku’s campaign. It’s shorter, darker, and honestly, a bit easier because you don't have to build your own deck. Riku’s decks are pre-set for each world.
The strategy here shifts to "Duel Mode." When you and an enemy play cards of the same value, you can trigger a duel. You then have to rapidly play cards from your deck to win the clash. If you’re fast, Riku performs a massive AOE attack that clears the screen. It’s a totally different rhythm, but it’s a nice break from the micromanagement of Sora’s deck.
Practical Steps to Master the Game
- Farm the "Aladdin" Friend Card: In Agrabah, Aladdin’s friend card drops tons of Moogle Points. Use these to buy better card packs.
- Organize by Number: When building a deck, try to keep your cards in descending order. This makes it easier to know what’s coming up next without staring at the HUD.
- Abuse the "Stun" Mechanic: Many bosses have a long recovery time after a Card Break. Use that window to reload your deck, don't just mash attacks.
- Key to Rewards: These rooms contain the best cards in the game (like the Lionheart or Diamond Dust). You start finding these special keys after Floor 7. Don't ignore them.
Success in this game is about 80% preparation and 20% execution. If you go into a boss fight with a disorganized deck, you’ve already lost. But if you take ten minutes to stack your Sleights and pack your 0s, you’ll breeze through the story and finally understand why people actually love this weird, card-slinging experiment.
Go to the deck edit menu right now. Look at your current setup. If it’s just a random pile of Kingdom Keys and Potions, clear the whole thing. Start by placing three cards that form a Sonic Blade (values totaling 20-23). Then, place three cards for a Fire Raid. Put a 0 at the very end. Test it on some Shadows. You’ll feel the difference immediately. Once you stop fighting the system and start using it to cheat, the game actually becomes fun.
