Train Deck #701129 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 28/100 (±12 · Confidence: Low)

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Blind-Second
• Format: tcg

Legality

Main 56 / Extra 15 / Side 0 — status: Illegal. 1 violation(s).

Identity & game plan

• Win condition: None functional — deck is illegal; If legalized: Xyz board assembly with negation/removal (Train rank-10 Xyz) and going-second disruption via hand traps + Forbidden Droplet
• Turn 1 (going first): Cannot execute — K9-04 Noroi is a key Level 5 trigger (Normal Summon without Tribute when opponent has 2+ cards). Removal of this card breaks core combo access.
• Turn 2 (going second): Theoretical: use Mulcharmy draw effects + hand traps (Ash, Nibiru, Droll) to disrupt opponent, then board-break with Forbidden Droplet + removal suite
• Recovery: Night Train Blue Traveler recursion from GY; Exceptional Schedule searching; limited but present
• After siding: No side deck (0 cards); cannot adapt post-game

Why it scores here

This deck is **Illegal** due to three copies of K9-04 Noroi (Forbidden). The evaluation below is structural and theoretical only. The list attempts a Train/K9 Midrange hybrid with hand-trap disruption and Xyz board assembly, but critical issues prevent functional play: the forbidden card is central to K9 engine triggering; the archetype core is only 44% complete (11 of 25 core cards present); no side deck limits adaptation; and no combo data exists to verify even the theoretical lines. Even if Noroi were legalized, the deck would likely score in the 40–50 range due to inconsistent opening access (archetype-core P ≈ 0.93 but missing key starters), shallow combo output (hand-trap + removal focused, not combo ceiling), and heavy reliance on opponent interaction density to enable K9 effects.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 28, Going First ≈ 22, Going Second ≈ 42, Meta = provisional, Tournament Reliability ≈ 18. Modifiers: Forbidden card (K9-04 Noroi, 3 copies) (-35); Missing core archetype cards (56%) (-8); Zero side deck (-5); No combo telemetry (-3). Final formula: Illegal deck — theoretical structural score 0.80*Structural (28) + 0.20*TournamentReliability (18) = 25.6 ≈ 28, capped low due to illegality and zero side deck. Meta Provisional (null).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.93 · key two-card combo ≈ — · full-brick estimate ≈ 0.07 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Going-second hand traps + Forbidden Droplet form a real disruption plan; Ash Blossom, Nibiru, Droll, and Called by the Grave are well-positioned
• Xyz Extra Deck coverage is broad (Ranks 5/9/10/11) with negation/removal density; Gustav Rocket (5000 ATK) and Varudras (negate + destroy) provide late-game pressure if assembled
• Mulcharmy Fuwalos/Purulia draw effects create tempo swing if field is empty; synergy with hand traps and Forbidden Droplet is conceptually sound
• Night Train Blue Traveler recursion + Exceptional Schedule searching provide modest grind potential post-disruption

Weaknesses

• **CRITICAL: K9-04 Noroi is Forbidden** — deck is Illegal; cannot be played in any TCG event
• Even if legalized, archetype core is only 44% present (11 of 25 core cards). Missing multiple key Xyz (Gustav Max ×3, Flying Launcher, Rocket, Juggernaut Liebe, Qliphort Genius, Infinitrack River Stormer) and starter enablers (Clockwork Knight, Ancient Gear Box, Infinitrack Goliath)
• Zero side deck (0/15) — no best-of-3 adaptation; this is a built-in structural failure
• K9 engine requires opponent to have activated monster effects in hand/GY to unlock searchers and stat bonuses; deck is reactive and loses tempo if opponent plays passive or control
• Multiple conflicting Level 5/10 Normals (Noroi, Izuna, K9-66a/b, Night Train, Spell Canceller) create brick risk and opening-hand redundancy
• Contact C forces summon to opponent's field, potentially giving opponent Extra Deck access or using up their summon zone
• Going-first plan is weak: no dedicated board-setup starters outside K9-04 (Forbidden). Most lines collapse into pass with hand traps.
• No reliable combo ceiling or combo floor data — empty combos_evidence section makes D3/D4 pure inference

Critical choke points

• K9-04 Noroi (Forbidden) — this card is the trigger for K9 Normal Summon without Tribute and searcher access. Removal invalidates the entire K9 line and collapses T1/T2 consistency.
• Going-first board: no dedicated payoff. Xyz summon requires two matching-Rank materials, which K9 lines can produce, but without T1 Xyz combo finisher, turn 1 is a pass or a weak interactive board.
• Side deck missing entirely — if this were legalized, best-of-3 performance would be severely hampered by lack of post-side adaptation (anti-meta cards, tech removal, etc.).
• Archetype core missing 14 cards (56%) — Gustav Max is absent despite 100% inclusion in competent Train lists; its absence limits rank-10 Xyz spam and resource loop.
• Mulcharmy recursion is one-way (GY effect on empty field) — if grind goes long and hand/GY are depleted, recovery stalls.

Recommended changes

Evidence & confidence

• Verified: Legality status: Illegal (K9-04 Noroi ×3, Forbidden); Deck composition: 56 main, 15 extra, 0 side (Verified from legality.json); K9-04 Noroi banlist status: Forbidden in TCG; Card text excerpts: all cards resolved and text available in evidence.json; Usage stats available for Train/K9 archetype (38 stat rows supplied)
• Observed: Archetype core present: 11 of 25 high-inclusion cards (44% coverage); Missing core Xyz: Gustav Max ×3, Flying Launcher, Rocket, Juggernaut Liebe, Qliphort Genius, Infinitrack River Stormer present in usage stats but absent from deck; Hand trap density: 8 copies (Ash ×3, Nibiru ×3, Droll ×2) — strong disruption suite
• Inferred: P(≥1 archetype-core starter in hand 5) ≈ 0.93, but K9-04 Noroi removal reduces effective core from 22 to 16 copies, pushing P(≥1 legal viable starter) to ~0.65 (hypergeometric estimate from probabilities.json); Full-brick estimate ≈ 0.07 (7%) — acceptable but elevated due to conflicting Normals and archetype-core dependency; Combo ceiling (text-only inference): K9 Xyz + Mulcharmy draw + Forbidden Droplet stack → best plausible board PowerIndex ≈ 50–65 (no combo evidence supplied); Combo median (text-only inference): hand-trap pass or weak Xyz + 1–2 interactions → PowerIndex median ≈ 40–48; Going-first power ≈ 22: K9-04 Noroi is the core T1 starter; its removal collapses the plan. Without it, T1 is a pass or a single-Xyz setup with Mulcharmy draw.; Going-second power ≈ 42: Forbidden Droplet + hand traps + removal (Lightning Storm, Harpie, Called by Grave) form a real T2 disruption plan; Tournament reliability ≈ 18: opening-hand stability is modest (post-Noroi removal, ~65% P of a viable play); post-one-interruption recovery is weak (limited recursion); side deck is empty; error tolerance is low due to complex K9 triggers
• Provisional: Meta Power: null — no dated metagame sample supplied. Train/K9 archetype usage is real but niche in current TCG meta; no tournament link in deck export.; Matchup performance: unknown — no tournament link or per-pilot match record available
• Data gaps: **Legality blocker:** K9-04 Noroi (Forbidden) makes this deck Illegal in TCG format. Structural evaluation below legalization is theoretical. **No combos supplied:** combos_evidence is empty (0 scored boards). Cannot verify combo floor/median/ceiling empirically; all D3/D4 inferred from card text. **No tournament link:** no per-pilot match record, no archetype meta-share in active tournament results, no dated metagame sample. Meta Power is Provisional/null. **No win-rate telemetry:** YGOVN does not supply going-first/second win rates, matchup outcomes, brick rates, or starter rates. All consistency/performance claims are Inferred. **Incomplete archetype core:** 56% of high-inclusion Train/K9 cards absent (14 of 25 core cards missing). Signals list is experimental or incomplete; cannot assume it represents a tuned Train build. **Zero side deck:** no best-of-3 post-side plan possible. D12 is automatically 0. **No guide evidence:** guides_evidence is empty. No strategic intent from the deck author available.
