- Collection book (Index) records every cat card you obtain in Collect Cat Cards, including special variants.
- Mutated cards count separately: Shocked, Cosmic, and Aurora versions should be logged apart from normal copies.
- Unique cards first: Reserve hard-to-replace cards for Index milestones before assigning them to displays or battle teams.
- Duplicates fuel progress: Extra copies are your tools for stands, PAW grading, and tower teams.
- Recheck often: Rerun your allocation plan after every major unlock or weather event.
What Is the Collect Cat Cards Collection Book?
The collection book — called the Index in-game — is the backbone of long-term progression in Collect Cat Cards. Every cat card you pull from a pack is logged as an entry, and variants such as Gold, Rainbow, and Holo, along with weather mutations, expand how many entries you can realistically fill. Broad coverage of the Index is rewarded separately from cash income or tower battles, which means collecting is its own progression track rather than a side effect of farming.
The key tension is that the same cards serve three competing purposes: Index completion, display-stand income, and tower combat teams. A card locked into one role is unavailable for the others, so the players who finish the collection book fastest are the ones who deliberately allocate copies instead of using whatever they pull next.
| Index Goal | What It Requires | Main Risk |
|---|---|---|
| Fill standard entries | One copy of each base cat card | Selling unique cards as duplicates |
| Log variant entries | Gold, Rainbow, or Holo copies | Overwriting a variant with a normal copy in records |
| Log mutated entries | Shocked, Cosmic, or Aurora cards | Processing mutations as ordinary duplicates |
| Maintain 100% tracking | Regular review after every pack | Letting new pulls pile up unsorted |
During weather events, new cards may carry a mutation label. Inspect each pull before selling, displaying, or converting it — the first copy of a valuable mutation is usually worth far more as a permanent Index entry than as temporary cash.
How Special Variants Fill the Collection Book
Special variants are where the collection book gets deep. A single cat card can exist in a normal version, multiple rarity treatments (Gold, Rainbow, Holo), and weather-mutated versions — each of which is tracked distinctly in your collection records. That is why duplicate management matters so much: your third copy of a common cat might be disposable, but your only Cosmic version of that same cat is a milestone.
Gold Cards
- Distinct gold treatment on the card
- Higher collection value than base copies
- Keep the best copy before using extras
Rainbow Cards
- Eye-catching rainbow finish
- Strong showcase and display appeal
- Prime PAW grading candidates
Holo Cards
- Holographic foil effect
- Sits among the most desirable variants
- Protect unique copies for the Index
| Variant Type | Collection Priority | Handling Advice |
|---|---|---|
| Gold | High | Keep first copy, display or grade extras |
| Rainbow | Very high | Reserve for showcase or grading |
| Holo | Very high | Log in Index before any other use |
| Shocked (mutation) | High | Record separately from normal version |
| Cosmic (mutation) | Very high | Preserve the best copy first |
| Aurora (mutation) | High | Store at least one meaningful copy |
Treat every variant as its own entry. Before selling or displaying any card, ask: is this my only copy of this version? If yes, it belongs in the collection book, not on the market.
Step-by-Step: Completing Index Entries Efficiently
Follow this workflow whenever you open packs so new cards are sorted into the right role immediately instead of creating backlog.
Inspect every new pull
Check each card for rarity treatment, a mutation label, and its cash value. Weather-event pulls deserve extra attention because mutation chances cluster around active events.
Check the Index first
Open your collection records and confirm whether this exact version already has an entry. If it is missing, the card is a milestone — lock it in before anything else.
Assign unique copies to collection
Reserve your only copy of any rare, variant, or mutated card for the Index. Do not commit it to a display setup or tower team without a replacement plan.
Route duplicates by need
With the entry secured, send extra copies where they help most: display stands for income, PAW grading for high-value cards, or your tower lineup for combat.
Revisit after big changes
After unlocking a new pack tier, a mutation event, or a tower stage, redo the allocation. Your best card roles shift as the collection grows.
Every unique card you protect is permanent Index progress. Cash and tower stages can be retried — a sold unique mutation often cannot.
Balancing the Index with Displays, Grading, and Towers
The collection book does not exist in a vacuum. Display stands generate the cash that funds your packs, PAW grading raises the value of your best cards, and tower battles push combat progression. A clean allocation plan keeps all four systems fed.
| Card Type | Index | Display Stand | PAW Grading | Tower Team |
|---|---|---|---|---|
| Only copy, rare/variant | Yes | No | After entry secured | No |
| Duplicate strong earner | Already logged | Yes | Optional | Situational |
| High-rarity variant extra | Already logged | Showcase | Best use | No |
| Duplicate combat card | Already logged | Backup | No | Yes |
| Common duplicate | Already logged | Yes | Avoid | Early game only |
Before sending a card to PAW, confirm it is not needed for an active display income loop, an Index milestone, or your current tower team. Plan around the card being unavailable during grading.
Key habits that protect collection progress while farming:
- Keep display cards and collection cards mentally separated at all times.
- Use duplicates for income whenever possible, so uniques stay free.
- Keep one reserve copy of especially useful combat cards before committing the rest.
- Recheck displays after completing any collection or combat objective.
Collection Book Milestones Checklist
Collection Book Goals:
- Log one copy of every base cat card you pull
- Record at least one Gold, Rainbow, or Holo variant entry
- Secure one Shocked, Cosmic, or Aurora mutation entry
- Establish a duplicate pipeline feeding your display stands
- Send a high-value variant card through PAW grading
- Complete a full reallocation review after your next weather event
Many collectors keep a simple personal checklist of missing entries. Knowing exactly which cards and variants you still need makes pack-opening decisions and duplicate handling much faster.
FAQ
Q: Do mutated cards count as separate entries in the Collect Cat Cards collection book?
Yes. Mutated versions such as Shocked, Cosmic, and Aurora are treated as distinct from the normal version of the same cat card. Record them separately and protect at least one copy of each valuable mutation for your Index progress.
Q: Should I sell duplicate cards from my collection book?
Only after confirming the Index entry for that exact version is secured with another copy. Once the entry is safe, duplicates can support display income, tower teams, or other progression needs without hurting collection progress.
Q: Which cards are worth sending to PAW grading?
Focus grading resources on rare, variant, or mutated cards that would be difficult to replace. Avoid grading ordinary duplicates or cards needed for short-term tasks, and make sure the card is not essential to your active display setup or tower team.
Q: How do weather events affect the collection book?
Weather events are the main window for obtaining mutated cards, which fill separate mutation entries in the Index. Participate during active events and inspect every resulting card for a mutation label before processing it as an ordinary duplicate.
