Phantasm Spiral Deck #770625 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 56/100 (±7 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Stun, Midrange
• Format: tcg

Legality

Main 43 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Level 10 Sacred Beast Special Summons (Calamity, Infinity, Inferno) and Extra Deck boss monsters (Chaotic Phantasmal Sacred Beasts, Galaxy Destroyer, Gustav Rocket, Raviel) that end the game at 4000 to 5000 ATK; Gustav Max direct damage and recursive Phantasm grind through Martyr and Released
• Turn 1 (going first): Open a Martyr (Lv1) or Summoner, search or place a Sacred Beast Field Spell or Continuous card, then reveal Level 10 Sacred Beast monsters from hand to fetch more SB pieces toward Raviel or Chaotic
• Turn 2 (going second): Use the 5 hand traps (Ash Blossom x2, Ghost Ogre x2, Droll & Lock Bird) and Sacred Beasts Skyfall to protect the first starter, then rebuild the Phantasm line from the GY
• Recovery: Recover Martyr and Released from the GY via their GY effects, rebuild through Card of the Soul and Tokusano Shinkyojin, and re-fire Fallen Paradise
• After siding: No sideboard is registered, so there is no post-side plan; the list cannot adjust to matchups

Why it scores here

Scored as a connected Sacred Beast system, not an average of card scores. The deck reliably finds a starter: 24 searcher-text cards put a searcher in the opening five at about 99% (Inferred), and three Martyr Lv1 starters plus Summoner give the engine a live T1 route. Conversion is strong on paper: the Level 10 Sacred Beast Special Summon targets and the 4000 to 5000 ATK Extra Deck bosses give a high ceiling, but no recorded boards exist, so the median output is text-only and held near the middle. Interaction is layered (two Ash Blossom, two Ghost Ogre, Droll, Skyfall, Combined Assault, Illusion Gate, Galaxy Destroyer, Gustav Rocket), which earns the endboard and resilience scores. Score is pulled down by the lack of any sideboard, by only 26 of 58 off-archetype-tagged copies being core Phantasm (45 percent purity, engine dilution), and by the absence of tournament or win-rate evidence. Popularity did not earn points.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 63, Going First ≈ 66, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 56. Modifiers: No sideboard / no post-side plan (-3); Engine dilution (45% core purity) (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); structural 62.84 gives 61.5 before modifiers

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.32 · key two-card combo ≈ — · full-brick estimate ≈ — (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense searcher and starter access (24 searcher-text cards, 3 Martyr Lv1 starters)
• Layered hand-trap and negation package (Ash Blossom x2, Ghost Ogre x2, Droll, Skyfall, Combined Assault, Galaxy Destroyer)
• High-ATK Extra Deck closers (Chaotic 5000, Galaxy Destroyer 5000, Gustav Rocket 5000, Raviel 4000)
• Legal list with all restricted cards at or under legal copies (Verified)

Weaknesses

• No sideboard, so no post-side adaptability
• Only 45 percent core Phantasm purity; 17 generic cards and mixed sub-archetypes (Dark World, Train, Orcust, Mulcharmy, Thunder Dragon, Tistina) dilute the engine
• No recorded boards, so floor and median output are unknown
• Usage-stat core list is largely cards this deck does not play (20 percent present), so it does not validate the build

Critical choke points

• Level 10 Sacred Beast summon requires a Sacred Beast card effect; without Martyr, Summoner or a Sacred Beast Spell/Trap the engine does not start
• Single Gustav Max (Limited) and single S:P Little Knight (Limited) are one-of cards with no backup

Recommended changes

Evidence & confidence

• Verified: Main 43, Extra 15, Side 0 are within TCG size rules; All restricted copies (Droll x1, S:P Little Knight x1, Gustav Max x1, Ash Blossom x2) are within legal copy limits; Phantasm copies 26, generic 17, other sub-archetypes 15 (archetype_spread)
• Inferred: Starter access P(≥1 Martyr in 5) ≈ 0.32 and searcher density near 0.99; Interaction density and endboard quality from card text; Going-second hand-trap coverage ≈ 0.55
• Provisional: Meta and matchup fit (D13) because no tournament or dated meta sample exists
• Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and pilot match record absent No win-rate or brick/starter telemetry exists in YGOVN Usage statistics core list mostly names cards from other archetypes (Necroquip, Fiendsmith, Unchained, Triple Tactics), so it cannot validate this build Meta Power is Provisional Deck title is null in the export
