2 Level 5 WATER monsters During either player's turn: You can detach 1 Xyz Material from this card, then target 1 face-up monster on the field; its ATK becomes half its current ATK until the end of your turn.
Number 94: Crystalzero — Power Evaluation
Final Score: 65 ± 5 · Confidence: Medium
- Intrinsic: 63 · Deck: 67 · Meta: provisional
- Primary role: Removal/Negation · Secondary: Material body
Why it scores here
Number 94: Crystalzero is a specialized board control piece providing soft disruption through ATK reduction in water-based decks. While its effect is flexible—working on either player's turn and allowing multiple activations—the limitation to 50% ATK reduction rather than hard removal or negation restricts its disruptive ceiling. Its real value lies in strong material utility as a Rank 5 Xyz (2200 ATK body) and deep integration into Fish, Shark, and Umi Control archetypes where Level 5 WATER materials are abundant. The card scores well on accessibility and material utility within home archetypes but lacks raw combo power and resource advantage generation.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 65 | Accessible across multiple water-based archetypes (23 distinct in sample) with abundant Level 5 WATER partners; 101 total decks with 52.5% in Fish, 20.8% in Shark variants (verified). |
| Combo & Conversion | 35 | Zero combo boards recorded; standalone effect provides one-time ATK reduction without building toward further synergies or generated advantage (verified). |
| Resource Economy | 50 | Costs one Xyz Material per activation for soft board control; no card advantage generation; roughly even resource trade (inferred). |
| Effect & Interaction | 65 | Reduces target monster's ATK to 50% of current value until end of your turn—soft disruption that doesn't prevent summons or effects; situational against effect-reliant decks (verified). |
| Material Utility | 70 | 2200 ATK Rank 5 Xyz with WATER attribute and Warrior type; usable as material for higher Rank Xyz constructs; respectable body remains even if effect negated (inferred). |
| Resilience & Flexibility | 60 | Effect works on either player's turn and allows multiple activations per turn if materials remain; no inherent protection but flexible across turns; reset on opponent's turn limits persistence (verified). |
| Deck-Building Efficiency | 65 | Requires 2 Level 5 WATER monsters—water-type locked, not generic; average 1.28 copies per deck (79 at 1, 16 at 2, 6 at 3) suggests utility rather than necessity (observed). |
Calculation
Weight profile: 0.7 Removal/Negation + 0.3 Material body. Intrinsic ≈ 63, Deck ≈ 67, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Flexible timing—activates on either player's turn
- Multiple activations possible per turn if Xyz Materials remain
- Respectable fallback stats (2200 ATK) even if effect negated
- Strong synergy with abundant Level 5 WATER partners in home archetypes
- Deep integration into Fish, Shark, and Umi Control strategies
Weaknesses
- Soft disruption only; ATK reduction is ineffective against effect-centric decks
- Requires Xyz Material detachment each use; limited by material count on field
- Not universally splashable; water-archetype-dependent
- Effect resets after your turn; no persistent board lock
- Single-effect capability; no combo generation or card advantage
Counters / choke points
- Direct removal or banishment bypasses the ATK reduction
- Xyz effect negation or blocking (prevents detachment)
- Cards that block Material detachment
- Decks relying on effect-based interactions rather than ATK-based damage
Best use
Board control and soft disruption in water-based Xyz strategies. Decks: Fish, Shark, Umi Control.
Evidence & gaps
- Verified: Requires 2 Level 5 WATER monsters to summon; Effect: detach 1 Xyz Material, target 1 face-up monster, reduce its ATK to 50% until end of turn; Appears in 101 recent decks with primary homes in Fish (52.5%), Shark (20.8% combined), Umi Control (5.9%); Average 1.28 copies per deck (79 decks running 1 copy, 16 running 2, 6 running 3); Top partners are Level 5 WATER monsters and Xyz monsters including Buzzsaw Shark (80.2%), Lantern Shark (72.3%), Bahamut Shark (42.6%)
- Observed: Accessible across 23 distinct archetypes in the deck sample, predominantly water-based; Used in control (56.4%), mixed aggro/control (26.7%), and other (16.8%) gameplay types; Synergy with higher-rank Xyz monsters suggests use as material in advanced lines; Copy distribution skews toward 1-2 per deck, indicating utility role rather than core engine
- Inferred: Provides soft board control through reversible ATK reduction; effective against ATK-reliant threats; Can activate multiple times per turn if material supply remains, offering flexible disruption window; 2200 ATK body is functional material even when effect negated; Material cost (1 Xyz Material per activation) limits activation frequency and cumulative disruption; Water-type requirement narrows portability outside water-based archetypes
- Data gaps: No combo boards recorded (0 appearances)—combo conversion and board integration assessed via text only; actual role in advanced lines unknown No guide mentions (0 guides)—role interpretation relies on deck frequency patterns, not expert strategy commentary No StatisticsCard data—archetype inclusion % and typical copy trends inferred from 101-deck sample only No banlist information—assumed 3-copy legal in all formats; no known ban status No detailed rulings—effect assumed straightforward; tricky interactions with banish/negate/material-lock effects not explored
