2 Level 4 Winged Beast-Type monsters Once per turn: You can detach 1 Xyz Material from this card; negate the effects of all face-up cards your opponent currently controls, and if you do, this card gains 300 ATK for each face-up card currently on the field, except this card (these effects are applied until your next Standby Phase).
Ice Beast Zerofyne — Power Evaluation
Final Score: 62 ± 8 · Confidence: Medium
- Intrinsic: 63 · Deck: 61 · Meta: provisional
- Primary role: Board breaker · Secondary: Removal / Negation
Why it scores here
Ice Beast Zerofyne earns its score from one effect: once per turn, detaching a material negates every face-up card the opponent controls, which is a strong board-breaking effect. Its 2000 ATK earns nothing on its own, and the ATK gain it can give itself is only a finisher. Accessibility and resilience hold the score down because it needs a Rank 4 Xyz built from two Level 4 Winged Beasts and the activation can be answered in the chain. Combo evidence is absent, so the combo axis rests on the card text alone.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 55 | Needs two Level 4 Winged Beast materials to Xyz Summon, and 239 of 239 sample decks run it, mostly in Harpie-type shells, but no combo starter or searched data is supplied (observed for the deck count, inferred for the Level 4 supply). |
| Combo & Conversion | 40 | Text-only inference: the negate-all effect and self ATK gain convert a board into a stronger single body, but no combo examples or power index are supplied (inferred). |
| Resource Economy | 40 | Costs one Xyz material per activation with no refuel or draw, so it trades resources without net card advantage (verified from text). |
| Effect & Interaction | 85 | Negates every face-up card the opponent controls once per turn, a strong and hard-to-replace board-wide effect that does not touch face-down cards or the hand (verified from text). |
| Material Utility | 15 | As an Xyz monster it consumes materials rather than providing them, and the evidence gives no material-body use (inferred). |
| Resilience & Flexibility | 45 | The activation can be responded to in the chain and the ATK buff ends at the next Standby Phase, so it lasts only one turn cycle (verified from text, inferred for the response risk). |
| Deck-Building Efficiency | 75 | Run at one copy in 214 of 239 decks with a 1.13 average and no garnets or locks, so it fits as a single slot (observed from deck data). |
Calculation
Weight profile: 0.7 Board breaker + 0.3 Removal/Negation. Intrinsic ≈ 63, Deck ≈ 61, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Once-per-turn negation of every face-up opposing card, a board-wide effect
- ATK gain scales with the number of face-up cards on the field
- Runs as a single copy with no garnet cost
Weaknesses
- Needs an Xyz already on the field and one material per activation
- Negates face-up cards only, not face-down cards or the hand
- The ATK gain ends at the next Standby Phase
- Depends on a supply of Level 4 Winged Beast monsters
Counters / choke points
- Responses to the activation in the chain
- Hand traps and removal used before the activation
- Plays that make the Xyz unsummonable or remove its materials
Best use
Board breaker / negation finisher in Harpie-type shells. Decks: Harpie (archetype 664), Tri-Brigade, Harpie (archetype 256), Traptrix, Floowandereeze. Suggested copies: 1.
Evidence & gaps
- Verified: Rank 4 XYZ requiring two Level 4 Winged Beast-Type monsters; Once per turn: detach 1 Xyz Material to negate all face-up opponent cards; Self ATK gain of 300 per other face-up card, lasting until the next Standby Phase; 239 of 239 sample decks run it, 214 at one copy
- Observed: 46.9% of sample decks are in the Harpie archetype (664); 76.2% of decks are gameplay type 7; Top partner co-occurrence is 74.1% for Harpie's Feather Duster; No recorded combo boards include the card
- Inferred: Negating all face-up cards is a board-breaking effect whose value depends on how many face-up cards the opponent has; Level 4 Winged Beast supply in Harpie shells makes the Xyz summon reliable in those decks
- Data gaps: no combos supplied — combo conversion is text-only inference no guides supplied no banlist token — assumed 3 copies (unlimited) no usage statistics (StatisticsCard) — archetype inclusion % inferred from deck sample only no level or race data for partner monsters — Level 4 Winged Beast supply in Harpie shells is unverified
