Kingdom Hearts - Chain of Memories (Europe) (EnFrDeEsIt)

Mastering Kingdom Hearts: Chain of Memories on GBA starts with understanding the core card-based combat system, so our first key tip is to learn how card breaking works. Any card can break an opponent’s attack if it has a higher or equal value than the enemy’s card, and 0-value cards can break any attack regardless of its value — always keep 2 to 3 0-value cards in your deck to counter massive boss attacks from Organization XIII members. Next, focus on building a balanced deck: don’t fill your deck with only high-damage, high-CP cards, as this will leave you unable to draw multiple cards in a single turn and leave you open to deadly counterattacks. Early in the game, stick to a mix of low-CP basic attack cards, 1-2 low-cost magic cards (like Fire or Blizzard for group enemy damage), and one early summon card to handle different enemy types without overloading your CP. When leveling up, prioritize increasing your total CP capacity first before adding extra card slots, as this lets you include stronger cards later without crippling your draw rotation. For progressing through Castle Oblivion, each floor requires you to use map cards to unlock new rooms — save high-value map cards that open bonus reward rooms for when you need to stock up on healing items or rare card upgrades. If you’re struggling against a tough Organization XIII boss like Larxene or Marluxia, study their patterns: most bosses alternate between small combo chains and one massive finishing attack, so save your 0-value cards specifically for that finishing blow to avoid taking massive damage. Once you beat the main Sora story, you unlock the bonus Riku Reverse/Rebirth campaign, which features a streamlined deck system and darker story arc — for Riku’s mode, focus on stacking dark attack cards and use his innate dark break mechanic to clear groups of enemies quickly.
