Phantasm Spiral Deck #771576 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Stun, Toolbox
• Format: ocg

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Sacred Beast Level-10 monsters (Hamon, Raviel, Uria) Special Summoned by Calamity/Infinity/Inferno, then Extra Deck boss monsters (The Chaotic Phantasmal Sacred Beasts 5000 ATK, Gustav Rocket 5000 ATK) to close the board.; Mulcharmy draw-engine chip damage and Gustav Max direct damage; no combo evidence to confirm either converts.
• Turn 1 (going first): Open a Phantasm Spell/Trap or Sacred Beast starter, reveal a Level-10 Sacred Beast from hand to Special Summon it, and protect the board with Ash Blossom, Ghost Ogre, Infinite Impermanence and Solemn Judgment.
• Turn 2 (going second): Use hand traps (Ash Blossom, Ghost Ogre, Droll & Lock Bird, Nibiru) to break the opponent's first summon or search, then rebuild through Summoner, Thunderclap, Released and Martyr.
• Recovery: Rebuild from the GY and banishment through Abyss, Martyr and Released recursion, and Fallen Paradise's Special Summon from GY, banish, or Deck.
• After siding: No side deck is registered (side_count 0), so no post-side plan can be assessed.

Why it scores here

The deck was scored as a connected Sacred Beasts system, not as an average of its card scores. Its searcher density (23 searcher-text cards, P(at least one in a 5-card opening hand) ≈ 0.94) makes the engine likely to find a starter, though the archetype core is only ~0.69 to be present in opening hand, and 26 of its 70 off-archetype copies are generic cards. Interaction is the strongest part: 12 hand traps and 8 negation-text cards give high interaction density, and the going-second hand-trap probability is ≈ 0.79. Closing power comes from 4000–5000 ATK Extra Deck bosses, but no recorded boards exist to confirm median output or combo conversion, so those dimensions stay low-confidence. Popularity was not credited: the archetype-core usage stats show only 45.5% of core cards present, and no tournament data exists. The deck is Illegal (3 copies of Ash Blossom against a limit of 2), so the Structural score of 55 is capped to a theoretical 35 final score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 55, Going First ≈ 50, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: legality_over_limit (-8); no_side_deck (-4). Final formula: No reliable metagame: 0.80*Structural(55) + 0.20*TournamentReliability(42) = 52.4; modifiers total -12 (cap); Illegal cap applied -> 35. Theoretical/structural-only.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.94 · 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 hand-trap package gives a likely starter and strong interaction on both turn orders.
• Extra Deck bosses at 4000–5000 ATK give real closing power once the Sacred Beast engine lands.

Weaknesses

• Illegal list: the third Ash Blossom exceeds the Semi-Limited copy limit.
• No side deck and no combo or board evidence, so post-side and median output are unknown.
• Split sub-archetypes (Phantasm, Mulcharmy, generic) reduce engine coherence and add brick risk.

Critical choke points

• Level-10 Sacred Beast Special Summon requirement: most boss lines need a Level-10 Sacred Beast in hand or GY.
• Single-copy Extra Deck bosses (Gustav Max, Little Knight, Linkuriboh) limit recovery.

Recommended changes

Evidence & confidence

• Verified: Main 55, Extra 15, Side 0 counts are within the OCG size rules (main 40–60, extra 0–15).; Ash Blossom & Joyous Spring is over the copy limit (3 run, 2 legal) and the deck is Illegal.; Limited cards (Droll & Lock Bird, Harpie's Feather Duster, Linkuriboh, S:P Little Knight, Solemn Judgment, Gustav Max) each run 1 copy, which is legal.; Extra Deck breakdown is 3 Fusion, 7 Link and 5 XYZ, matching the card list.
• Observed: Usage stats show 5 of 11 archetype core cards present (45.5%).
• Inferred: Going-first and going-second estimates from hypergeometric hand probabilities.; Interaction quality and floor/median output from card text, since no boards exist.
• Provisional: Meta Power is null: no dated metagame sample.; D13 matchup fit is a placeholder pending a dated meta sample.
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference. No tournament link: archetype meta-share and per-pilot match record absent. No win-rate telemetry (going-first/second, matchup, brick or starter rates). No side deck registered, so post-side evaluation is not possible. Deck title is null.
