Build your lineup around the cards you own and the specific fight you are trying to clear. For one reported level 100 fight, players recommended a lineup of Illusion, Mirror, Mist, Rain, Shot, Thunder, Sword, and Fight, plus the Fire Syaoran character card; treat it as a stage-specific suggestion to try, not a guaranteed solution.
How team building works in Memory Key
Cardcaptor Sakura: Memory Key is a mobile collection and battle game. The US App Store listing describes it as a free iPhone and iPad app with in-app purchases, centered on collecting Sakura items and costumes: Apple App Store listing. A beginner guide describes story chapters as alternating between story scenes and battles, while a 2024 review says upgraded figures provide Sakura with stats. These secondary descriptions offer progression clues, but they do not establish a complete or authoritative account of current battle mechanics.
That means the practical starting point is the fight in front of you, not a universal ranking. Check the current in-game card descriptions and stage requirements, then choose from the cards and upgrades available on your account. The available sources do not verify card roles, attribute counters, skill interactions, or a best-in-slot lineup, so avoid assuming a card performs a particular function based on its name alone.
A reported lineup for the level 100 fight
In a September 28–29, 2024 Reddit discussion about beating level 100, a player recommended this lineup and said replies reported success with it:
#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.

- Mirror
- Mist

- Shot
- Thunder
- Sword
- Fight
- Fire Syaoran character card
This is community advice for that particular fight, not an official developer recommendation or a verified solution for other stages. If you own most of these cards, it can be a reasonable starting point. If one is missing, substitute a card you have and use the current in-game descriptions and stage requirements to guide your choice; the discussion does not establish which replacements are equivalent.
What to try when you are stuck
- Confirm the obstacle. Read the stage requirements and the descriptions for your available cards in the current game version.
- Adjust the lineup to your account. Start with the cards you own that appear relevant to the fight rather than pursuing a lineup you cannot assemble.
- Review upgrades. A 2024 secondary review reports that upgraded figures provide Sakura with stats. The level 100 discussion also mentions furniture upgrades as useful, but provides no controlled comparison, so neither source establishes how much either change will improve a particular fight.
- Try again and reassess. If the lineup fails, reconsider the cards and upgrades against the stage requirements instead of treating one community example as a guaranteed fix.
Looking for a deck that worked for you?
Players asking “Is there a deck that worked for u guys ?” are often trying to clear one specific stage. If you ask for recommendations, include the stage number and the cards you own; that gives other players enough context to suggest a lineup they can compare with your situation. Advice may still vary by account, current balance, and game version.

What the available advice does not establish
