Jump for Cases Mutations Tier List
Which mutated animals to protect, place, and chase.
Mutations are how Jump for Cases turns a familiar species into a premium asset. A Mutated pet often outvalues a normal copy of the same base rarity, both for plot income and for collection flex. This page ranks mutation value, explains why mutated animals keep worth across rebirth cycles and sell filters, and shows how to avoid deleting them with Auto Sell.
Read alongside the Animals Tier List and Best Animals. Mutations modify those rankings — they do not replace learning base rarities.
Why mutations matter
- Economy: many mutated variants earn more than non-mutated peers.
- Scarcity: mutation rolls are rarer than base rolls at the same distance.
- Index goals: collectors track mutated forms separately (Players Hub).
- Script risk: Auto Sell Weak without Keep Mutated is a classic tragedy (Scripts).
If you only remember one rule: never mass-sell before scanning mutation tags.
Value ranking framework
Because Lucky Animals! can add new mutation styles over time (including neon-like or other named variants featured in community scripts’ keep filters), we rank by value bands rather than pretending a frozen species spreadsheet.
S — Mutated Legendary / Secret / flagship carriers
Top of the market. A Mutated Legendary or Mutated Secret-style exclusive is almost always a permanent keep. Place it, show it, and structure rebirth decisions so you do not panic-reset without understanding keep rules (Rebirth Guide).
Chase method: maximum controlled distance, luck codes (LuckyDuck, SEASON2), Season cases, and disciplined opening during buffs (Codes).
A — Mutated Epic / strong Mutated Rare
Highly placeable. These often beat normal Legendaries that underperform on income, depending on patch balance — always compare live earnings. Keep duplicates only if slots and index goals justify it; otherwise one plot copy plus cautious banking is enough.
B — Mutated Common / Uncommon with visible tags
Still valuable. A Mutated Common can deserve a slot longer than a plain mid Rare when the mutation bonus is real. Do not auto-trash them because the species name looks starter-level.
C — Non-mutated duplicates of low rarities
Not a mutation tier per se — listed as the contrast class you should sell freely once plots are healthy. This is what Auto Sell should target after Keep Mutated is enabled.
Neon and named mutation styles
Community tools frequently mention keeping Mutated and neon-style variants when auto-selling. Exact cosmetic names can change, but the operational lesson is identical:
- Identify the tag in inventory UI.
- Whitelist that tag before bulk actions.
- Prefer manual review after huge spin dumps from
LuckyW5/ Season rewards.
If a new mutation line launches mid-Season, assume it starts rare and valuable until proven otherwise on the Updates Hub.
Mutations vs base rarity (quick matrix)
| Base rarity | Normal keep? | Mutated keep? |
|---|---|---|
| Common | Early only | Often yes (B/A bump) |
| Rare | Situational | Usually yes |
| Epic | Often | Strong yes |
| Legendary | Yes | Hard yes (S) |
| Secret | Hard yes | Absolute priority |
When two pets compete for one slot, mutation + rarity usually beats rarity alone.
Protecting mutations during farming
Manual players
- After each case batch, sort Mutated into a mental (or hotspot) keep pile.
- Sell C-tier normals only after the sort.
- During luck windows, open first, sort second, sell third.
Script users (alt recommended)
- Enable Keep Mutated / equivalent before Auto Sell Weak Animals.
- Watch the first twenty sells.
- Disable sell automation after patches until filters are verified.

Mutations and rebirth
Confirm whether mutated animals persist through rebirth on your current patch — read the modal. Even if they keep, your plot arrangement may reset and need replacing. Build a post-rebirth shortlist that prioritizes mutated earners so income returns quickly (Money Farming).
Mutations and Tsunami sessions
Losing session momentum after a rare mutation drop hurts. When you hit a juicy Mutated Legendary mid-grind, consider safer Tsunami play and Weather spends until it is securely placed (Tsunami Survival). Do not AFK with an unplaced trophy in a volatile inventory state.
Hunting plan
- Raise jump power so you are not rolling pure commons (How to Jump Farther).
- Redeem luck codes when ready to play.
- Open Season / Legendary cases deliberately.
- Lock mutations onto the plot immediately.
- Update your personal index on the Players Hub goals.

Bottom line
Mutations are keep-first assets. Rank Mutated Legendary/Secret as S, treat Mutated mid rarities as serious A/B upgrades, and never let bulk sell logic touch them unfiltered. Base rarity still matters — mutation multiplies it. Play for distance and luck, then protect the shiny results like the plot anchors they are.
Frequently Asked Questions
Quick answers to the most common questions.
Are mutated animals better in Jump for Cases?
Usually yes. Mutated variants often out-earn and outvalue normal versions of the same species, especially at higher base rarities.
Should I sell mutated commons?
Generally no until you deeply understand their earn rate. Many mutated commons deserve slots longer than plain mid rares.
How do I avoid auto-selling mutations?
Enable Keep Mutated (or similar) before Auto Sell, and manually sort after big spin sessions. Test filters on an alt first.
Do new seasons add mutations?
Seasons can introduce new animals and variant styles. Watch Discord and Updates when banners change.
