• Format: ocg

Legality

Main 55 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Build a resilient Rank 8 Xyz board with negation and disruption, then pressure or grind through resources; Going-second board-breaking via hand traps and removal, recover through recursion
• Turn 1 (going first): Summon Starliege Seyfert or Schwarzschild Infinity Dragon into a Rank 8 Xyz (Number 107, Dragluxion, or Titanic Galaxy) with negate effects and material count
• Turn 2 (going second): Use hand traps (Ash Blossom, Infinite Impermanence, Evenly Matched) to disrupt opponent's board; deploy Lightning Storm or Harpie's Feather Duster; resolve Mulcharmy Fuwalos draw engines
• Recovery: Attach Xyz materials as cost to negate; banish from GY (Starliege Seyfert, Galaxy-Eyes Afterglow Dragon); resolve Tachyon Cloudragon tribute recursion; grind with Mulcharmy draw
• After siding: No side deck supplied; evaluation assumes main-deck consistency carries through best-of-3

Why it scores here

This deck opens a functional engine roughly 83% of the time (Seventh Tachyon/Ascension searchers or Starliege Seyfert draw engine), converting into a Rank 8 Xyz with 2–3 negation effects at a modest ceiling. The median output is constrained by reliance on Xyz attachment loops and hand-trap sequencing rather than explosive combo chains. Going-second is strong (Evenly Matched, Infinite Impermanence, Lightning Storm) and the Xyz suite provides reliable interaction, but offensive pressure is limited—bosses max out around 3000–4500 ATK and the deck grinds rather than closes quickly. Missing core cards (Maxx "C", Number 97: Draglubion, Number 38: Hope Harbinger) and the absence of combo evidence means consistency and ceiling estimates are inferred from card text and structure, not verified boards. No side deck is provided, so post-side resilience cannot be assessed.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 63, Going First ≈ 68, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: missing_core_cards (-3); no_combo_evidence (-2); no Side Deck (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional; no dated metagame sample)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.83 · key two-card combo ≈ — · full-brick estimate ≈ 0.17 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Consistent core engine (Seventh Tachyon/Ascension + Starliege Seyfert) with ~83% opening live rate
• Strong going-second disruption package (3x Evenly Matched, 3x Infinite Impermanence, Lightning Storm)
• Reliable Rank 8 Xyz production with layered negation (Number 107, Titanic Galaxy, Transmigration)
• Xyz attachment loops extend resource economy and enable follow-up plays
• Mulcharmy draw effects reward opponent summons and help grind through turns

Weaknesses

• Missing 7 of 14 archetype-core cards (Maxx "C", Number 97, Number 38, etc.) limits consistency and ceiling
• Median combo output is constrained; no explosive multi-summon chains
• Low offensive closing power; bosses capped at 3000–4500 ATK with no piercing or direct damage
• Reliance on Xyz attachment as negation cost reduces resilience if bosses are removed before effects resolve
• Single-choke-point vulnerability: disrupting the initial Seyfert or Seventh Tachyon search leaves hand with limited alternatives
• No side deck prevents post-side adaptation and format resilience assessment

Critical choke points

• Seventh Tachyon/Ascension searcher in opening hand is required for most lines; if hand contains no starter and no Starliege Seyfert, board is likely a single Xyz with no negate
• Rank 8 Xyz summon is the deck's main play; board-breaker disruption (Ash Blossom on Seyfert, Infinite Impermanence on Xyz summon itself) can reduce board to hand traps only
• Mulcharmy draw effects require opponent to summon; against stall/control opponents, they are dead cards
• Extra Deck is heavily weighted to Rank 8; Rank 5 and lower coverage is minimal (only Number C101 at Rank 5), reducing flexibility against non-Dragon strategies

Recommended changes

Evidence & confidence

• Verified: Deck is Legal in OCG format (55 main, 15 extra, 0 side; all restricted cards within copy limits); Card text for all 41 distinct cards resolved from YGOVN database; Archetype composition: Galaxy-Eyes/Tachyon/Starliege/Seventh/Mulcharmy hybrids with generic Xyz tools; Extra Deck breakdown: 14 Xyz, 1 Link; Usage statistics show core cards and 50% presence in this deck vs 14-card core list
• Observed: 8 hand traps (3 Ash Blossom, 3 Infinite Impermanence, 2 Droll & Lock Bird) in main deck; 15-card Extra Deck heavy on Rank 8 Xyz (7 slots); Rank 5 and lower sparse; Negation effects present on Number 107 (Battle Phase negate), Titanic Galaxy (Spell negate), Transmigration (Counter Trap negate); Searcher density: Seventh Tachyon, Seventh Ascension, Starliege Seyfert, Dragon's Light and Darkness (4 searcher cards at 3, 3, 3, 2 copies)
• Inferred: P(≥1 playable start in opening 5) ≈ 0.83 from hypergeometric draw odds on core searchers and Starliege; Full brick rate ≈ 0.17 (hands with no starter + conflicting Normal Summons or dead tech); Combo ceiling: Rank 8 Xyz with 2–3 negate materials + follow-up; constrained by Xyz attachment cost and single-line focus; Median board: one Rank 8 Xyz + 1 floating effect or hand trap in hand; limited independent lines; Going-first board relies on Seyfert into Rank 8 + Transmigration/Solemn backup; vulnerability if opener is disrupted; Going-second package: 8+ disruption cards capable of clearing field or locking Deck adds; effective against greed boards; Offensive closing: 3000–4500 ATK range on bosses; no piercing, direct, or multi-attack effects; closure is resource-based rather than tempo
• Provisional: Meta Power: no dated metagame sample; archetype meta-share and per-pilot tournament record unavailable; Matchup coverage: deck is positioned against mid-tier strategies (Xyz spam, going-first control); no tested sample vs top meta; Post-side resilience: no side deck provided; best-of-3 performance unknown
• Data gaps: No parseable boards in combo data; combo floor, median, ceiling are text-inferred only No tournament context; archetype meta-share and per-pilot match record absent No side deck supplied; post-side plans cannot be assessed No win-rate telemetry (going-first/second, matchup, brick/starter rates) in YGOVN; all frequency claims are inferred guide data is empty; archetype strategic intent not documented in YGOVN evidence
