Card Shuffle Feature¶

Reshuffle command cards to get better draws when current cards are suboptimal.

Overview¶

FGA can use the card shuffle feature (available through Mystic Codes or game mechanics) to get a new set of command cards when the current draw doesn't meet your criteria. This helps ensure you have effective cards available when dealing with difficult enemies.

Key Features¶

• Condition-Based Shuffle: Only shuffle when criteria aren't met
• Multiple Modes: Different conditions for different strategies
• NP Integration: Consider NP servant cards when deciding
• Automatic Detection: Scans current cards to evaluate quality

Shuffle Modes¶

How Shuffle Checker Works¶

    B -->|No| D[Select Best<br/>Available Cards]

Mode Details¶

None Mode¶

No automatic shuffling occurs:

• Use whatever cards are drawn
• Manual shuffle still possible
• Fastest processing

No Effective Mode¶

Shuffles when no class advantage cards are present:

Your Servants: [Saber] [Saber] [Caster]
Enemy: [Lancer]

Current Cards:
[Caster Buster] [Caster Arts] [Saber Quick] ...

None of these are "effective" against Lancer
(Sabers should have advantage)

Check: Are any cards marked as "Weak" affinity?
If none → Shuffle to try for better cards

When to use:

• Mixed class teams against single-type enemies
• Want to maximize class advantage damage

No NP Matching Mode¶

Shuffles when using NP but no matching face cards exist:

Using NP: Servant A (Slot 1)

Current Cards:
[Servant B] [Servant B] [Servant C] [Servant C] [Servant B]

No cards from Servant A available!

Shuffle to try for Servant A's cards
(for brave chain potential)

When to use:

• NP turns where brave chains matter
• Single target NP servants
• Maximizing main DPS damage

Card Affinity Detection¶

For "No Effective" mode, FGA checks card affinity:

A card is "effective" if it has the Weak affinity.

NP Usage Integration¶

For "No NP Matching" mode, FGA considers:

1. Which servant(s) are using NP this turn
2. What field slot each NP servant occupies
3. Whether any face cards belong to those servants

If NPs are queued but no matching face cards exist, shuffle is triggered.

Shuffle Limitations¶

Mystic Code Requirement¶

Shuffle typically requires a Mystic Code skill:

• Not all Mystic Codes have shuffle
• Skill may have cooldown
• Check your equipped Mystic Code

One Shuffle Per Turn¶

FGO limits reshuffling:

• Can only shuffle once per turn
• After shuffle, must use new cards
• No infinite rerolling

RNG Factor¶

Shuffling doesn't guarantee better cards:

• May get same or worse cards
• Class advantage cards not guaranteed
• Servant card distribution is random

Tips for Best Results¶

1. Match mode to strategy: Use the mode that fits your farming approach
2. Consider NP timing: No NP Matching is most useful on NP turns
3. Check Mystic Code: Ensure you have shuffle available
4. Don't over-rely on shuffle: Bad RNG can persist after shuffle
5. Test with your team: See how often shuffle triggers

Configuration Examples¶

Boss Farming Setup¶

• Mode: No NP Matching
• Goal: Maximize NP servant brave chains
• When: Wave 3 boss turns

Mixed Enemy Farming¶

• Mode: No Effective
• Goal: Always hit class weakness
• When: Variable enemy classes

Speed Farming¶

• Mode: None
• Goal: Fastest clear time
• When: Don't need optimal cards

Troubleshooting¶

Shuffle not triggering when expected¶

• Verify mode is correctly set
• Check if condition is actually met
• Cards may have the required affinity/servant

Shuffling too often¶

• Mode conditions are being met frequently
• Consider if shuffle is actually helping
• May want to switch to None mode

No improvement after shuffle¶

• Shuffle is random, same cards possible
• Card distribution depends on deck
• Consider team composition changes

Shuffle skill on cooldown¶

• Can only shuffle when skill available
• FGA checks for shuffle availability
• May need to wait for cooldown

Shuffle vs Card Priority¶

Both features work together:

1. Shuffle checks if current cards are acceptable
2. If not acceptable and shuffle available, reshuffle
3. Card priority then selects best from (possibly new) cards
