- Primary role: Board Breaker / Going-Second · Secondary: Removal, Material body
Why it scores here
This card scores as a situational board-wipe tool, not a combo generator. It appears in 180 sampled decks across 52 archetypes but zero combo boards, indicating it functions as a late-game or contingency board clear rather than a planned synergy. The material-intensive cost (detaching 3–5 Xyz materials) prevents reliable activation outside ideal late-game scenarios, and it offers no card advantage, recovery, or resource generation; its value rests entirely on disrupting an opponent's established board. The wide deck inclusion reflects its splashability into any Rank 4 shell, not intrinsic power.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 55 | Requires 3 Level 4 bodies and retention of 3+ Xyz materials; Harpies (28.9% of decks) and Yosenju (8.3%) supply these readily, but zero combo appearances show it is not reliably pre-planned in practice (verified: deck stats). |
| Combo & Conversion | 35 | Never appears in recorded combo boards and produces no independent board progression; activation demands materials already loaded on an Xyz, making it a reactive tool rather than a combo engine (verified: zero combos). |
| Resource Economy | 25 | Detaching 3–5 materials destroys opponent's cards but generates no card advantage, recovery, or refuel; a trade of materials for a field wipe is zero-sum at best (inferred: text, timing). |
| Effect & Interaction | 70 | Two-stage destruction (all other face-up monsters, or all opponent's cards) provides strong situational disruption; however, destruction is not hard negation and once-per-turn timing limits flexibility across turns (verified: card text). |
| Material Utility | 60 | As a Level 4 Dragon with 2400 ATK, it serves as functional Xyz material for Rank 4 plays; if the effect is negated or unneeded, the body retains moderate utility (inferred: type, attributes, stats). |
| Resilience & Flexibility | 40 | No recursion, protection, or multi-turn value; once materials are spent, the card is depleted for the turn and vulnerable to negation before activation (inferred: text, effect timing). |
| Deck-Building Efficiency | 75 | Splashable into 52 distinct archetypes with minimal deckbuilding cost; typically run as a single copy in decks already producing Rank 4 Xyzs; does not create garnets or deck locks (verified: 52 distinct homes, deck distribution). |
Calculation
Weight profile: Board Breaker / Going-Second (primary role, 100%). Intrinsic ≈ 60, Deck ≈ 57, Meta = provisional. Modifiers: Splashability (2); Material cost constraint (-3). Final formula: 0.40·Intrinsic + 0.60·Deck (decks present, combos absent)
Strengths
- Splashable into any Rank 4-heavy deck; 52 archetype homes without deckbuilding penalty
- Strong mid-to-late-game board clear when materials are abundant; effect 2 (destroy all opponent cards) is high-impact
- Generic Rank 4 body (Level 4 Dragon, 2400 ATK) provides material utility if the effect is unnecessary
- No banlist restrictions across all formats (TCG, OCG, MasterDuel, DuelLinks)
Weaknesses
- Never appears in combo boards (0/0); strictly a reactive or contingency play, not a synergy engine
- Material cost (3–5 Xyz materials) is prohibitive; most Rank 4 Xyzs enter with 2–3 materials, limiting effect activation to mid-turn or later
- Offers no card advantage or resource generation; pure removal with zero refuel or value repetition
- Vulnerable to negation before activation; no protection or recursion once spent
- Effectiveness drops sharply if the opponent has few cards; situational disruption value
Counters / choke points
- Hand traps (Ash Blossom & Joyous Spring, Ghost Ogre & Snow Rabbit) interrupt before activation
- Negation (Synchro Tuner, Solemn Judgment) stops the effect and wastes materials
- Removal (Lightning Storm, Tornado Dragon) eliminates the Xyz before it resolves
- Empty opponent board negates the card's effect entirely
Best use
Late-game board clear and contingency disruption for Rank 4-heavy decks. Decks: Harpies, Yosenju, Star Seraph, Photon, Mixed Rank 4 shells. Suggested copies: 1.
Evidence & gaps
- Verified: Rank 4 Xyz requiring 3 Level 4 bodies to summon (card text); Effect 1: Detach 3 materials → destroy all other face-up monsters (card text); Effect 2: Detach 5 materials → destroy all opponent's cards including S/Ts (card text); Included in 180/180 sampled decks across all formats (deck stat); Appears in 52 distinct archetypes (deck stat); Unlimited in all formats (no banlist token supplied)
- Observed: Harpies include it in 28.9% of sampled decks (52/180 decks) (deck stat); Yosenju include it in 8.3% of sampled decks (15/180 decks) (deck stat); Number 70: Malevolent Sin is the top co-occurrence partner at 62.8% (deck stat); Appears in 6 guides, consistently listed as a Rank 4 Extra Deck option (guide stat)
- Inferred: Board-clear role confirmed from dual destruction effects at different material costs (text); Material cost (3–5) indicates back-end contingency play, not a starter synergy (text + zero combos); Splashable due to generic Rank 4 status and minimal archetype restriction (deck distribution: 52 homes); Functions as a safety valve for Rank 4-heavy decks, included for coverage not synergy (inference: zero combos + high inclusion rate)
- Data gaps: No combo data supplied (zero appearances); combo-conversion score is text-only inference No StatisticsCard rows available; archetype inclusion percentages inferred from 180-deck sample only No banlist token; assumed unlimited (3 copies); score would drop if Forbidden or Limited-to-1 in any format Guide mentions are non-strategic; no detailed role explanation or synergy discussion from community sources
