If "Advanced Dark" is not in a Field Zone, send this monster to the GY. Once per turn, when your opponent activates a card or effect that targets your "Advanced Crystal Beast" card(s) or "Advanced Dark" (Quick Effect): You can negate the activation. Once per turn, when your "Advanced Crystal Beast" monster is targeted for an attack: You can negate that attack. If this face-up card is destroyed in a Monster Zone, you can place it face-up in your Spell & Trap Zone as a Continuous Spell, instead of sending it to the GY.
Advanced Crystal Beast Amber Mammoth — Power Evaluation
Final Score: 50 ± 10 · Confidence: Medium
- Intrinsic: 51 · Deck: 49 · Meta: provisional
- Primary role: Removal / Negation · Secondary: Material body
Why it scores here
Amber Mammoth reliably converts into a single Level 4 body that can negate targeted activations against Advanced Crystal Beast or Advanced Dark, and negate one attack per turn. Its near-universal deck inclusion (179 decks, 1-copy default, about 97% co-occurrence with Ruby Carbuncle) confirms it is a real, practical part of the archetype and earns the accessibility score, but high inclusion is not treated as intrinsic power. The 1700 ATK and 1600 DEF earn no points, and the mandatory send-to-GY clause when Advanced Dark is absent is a real restriction that pulls the deck and resilience scores down. Combo evidence is absent, so combo conversion and resource economy rest on text-only inference and stay low.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 60 | 179 of 179 sampled decks run it, mostly at 1 copy, with no searcher route shown in the evidence (observed, plus inferred route quality). |
| Combo & Conversion | 35 | The card makes one body and no board extension, and zero recorded boards exist to confirm any conversion (inferred from text). |
| Resource Economy | 30 | No draw, search or refuel text; the GY-send and Spell Zone replacement are positional rather than card advantage (verified from text). |
| Effect & Interaction | 55 | Two once-per-turn quick negates, one on spell/trap targets for ACB or Advanced Dark and one on attacks at ACB monsters, both narrowed to the archetype (verified from text). |
| Material Utility | 45 | Level 4 Earth Beast body with no as_material data, so material fit and negated-body value are inferred only (inferred). |
| Resilience & Flexibility | 50 | Survives a negate by converting into a Continuous Spell on destruction in the Monster Zone, but the Advanced Dark dependency is a fragile point (verified from text, inferred impact). |
| Deck-Building Efficiency | 45 | Single-copy default with no garnet, but the mandatory GY-send clause when Advanced Dark is off the Field Zone is a self-restriction that costs a few points (verified from text). |
Calculation
Weight profile: 0.7 Removal / Negation + 0.3 Material body. Intrinsic ≈ 51, Deck ≈ 49, Meta = provisional. Modifiers: Self-restriction (Advanced Dark dependency) (-3). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Near-universal inclusion in the sampled Advanced Crystal Beast decks, so it is almost never out of the deck.
- Two once-per-turn negates with flexible timing, one for targeted activations and one for attacks.
- Recovers as a Continuous Spell when destroyed in the Monster Zone, so it keeps some presence after a removal.
Weaknesses
- The mandatory send-to-GY clause when Advanced Dark is absent makes it unreliable as a standalone body.
- Negate targets are narrow: they must be Advanced Crystal Beast or Advanced Dark, or an attack at an ACB monster.
- No recorded combos, so the observed board impact of the card is unknown.
- Only 1700 ATK and 1600 DEF, so it has no body-based pressure.
Counters / choke points
- Hand traps and negates that stop it from being on the field before its effects are used.
- Opponent effects that destroy or bounce the monster while Advanced Dark is absent, which triggers the send-to-GY clause.
Best use
Negate a targeted activation or attack against an Advanced Crystal Beast or Advanced Dark, then sit as a recursive Continuous Spell if destroyed.. Decks: Advanced Crystal Beast. Suggested copies: 1.
Evidence & gaps
- Verified: Level 4 Earth Beast Effect Monster, 1700 ATK / 1600 DEF, archetype Advanced Crystal Beast (card text); Mandatory send-to-GY clause when Advanced Dark is not in a Field Zone (card text); Once-per-turn quick negate on targeted ACB or Advanced Dark activations (card text); Once-per-turn negate of attacks targeting an ACB monster (card text); Placement as a Continuous Spell when destroyed in the Monster Zone (card text); Appears in 179 of 179 sampled decks, 1 copy average, 151 decks at 1 copy (decks_evidence)
- Observed: Advanced Crystal Beast Ruby Carbuncle co-occurs in 97.2% of decks; Sapphire Pegasus in 96.6%; Crystal Bond in 95% (decks_evidence); Main-deck gameplay type 7 accounts for 84.9% of sampled decks (decks_evidence)
- Inferred: Advanced Dark appears to be a Field Zone dependency that the deck maintains, but the evidence does not state its card type; Combo conversion and resource economy are text-only estimates because no combo boards are recorded; Material fit for a Level 4 Earth body is inferred from level and attribute alone
- Data gaps: no combos supplied — combo conversion is text-only inference no guides supplied Advanced Dark card type and text are not in the evidence, so the Field Zone dependency cannot be fully checked no banlist token — assumed 3 copies (unlimited) no usage statistics (StatisticsCard) — archetype inclusion % inferred from deck sample only
