Therions Deck #758657 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 29/100 (±10 · Confidence: Low)

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

Legality

Main 59 / Extra 16 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Train Xyz boss pressure: Superdreadnought Rail Cannon Gustav Rocket (5000 ATK) and Juggernaut Liebe (4000 ATK), with Gustav Max as the material/entry route (Inferred from card text); Flying Launcher and Super Dora boards with Kaiju/Cyber/Therion negation and removal support (Inferred)
• Turn 1 (going first): Open a Train starter (Exceptional Schedule, Night Train Blue Traveler or Urgent Schedule) and build toward a Level 10 Xyz; plan not verified by combo data
• Turn 2 (going second): Hand traps (Ash Blossom, Droll and Lock Bird, Maxx C, Red Reboot, Cyber Dragon) to answer the opponent's first summon, then rebuild a Train board; plan not verified by combo data
• Recovery: Night Train and Exceptional Schedule GY/banish effects, plus Infinitrack Trencher and Gizmek recursion (Inferred from card text)
• After siding: Not evaluable: the deck has no Side Deck (side_count 0)

Why it scores here

The deck is Illegal: it runs 3 copies of Superdreadnought Rail Cannon Gustav Max against a Limited limit of 1, and its Extra Deck has 16 cards against a maximum of 15. Its Main Deck (59 cards) is within size, and Ash Blossom at 2 copies is legal. Consistency is weak on the evidence: no combos were recorded, and the exact archetype purity is 0%, with the Main Deck spread across Train, Infinitrack, Cyber, Greed, Kaiju and others. The starter probabilities are low (about 0.24 for a 3-copy card in a 5-card opening hand, and 0.37 for the 5-copy archetype core), so the deck has a real brick risk. Its interaction package (11 hand traps, 18 negation-text cards) and high-ATK Train Xyz bosses give it some end-board and closing value, but these were scored from card text and flags, not from observed boards. The score is capped low because the deck is illegal as built, and it was not produced by averaging card scores or from archetype popularity, which was not available here.

Dimension scores

How the score was computed

Strategy profile: Midrange primary only; Toolbox not blended into weights. Structural ≈ 42, Going First ≈ 40, Going Second ≈ 38, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: illegal_as_built (-12). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); 0.80*42.45 + 0.20*35 = 40.96, then -12 illegal-legality modifier = 28.96, rounded to 29 (illegal deck capped low; theoretical/structural only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ — · 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

• Large searcher-text density (16 cards) helps find the right piece
• Eleven hand traps and multiple negation effects give interaction on both turns
• High-ATK Xyz bosses (Gustav Rocket, Liebe, Zeus) provide closing stats

Weaknesses

• Illegal as built: Gustav Max at 3 copies (limit 1) and 16 Extra Deck cards (limit 15)
• No recorded combos, so consistency and conversion rest on text and probability alone
• Exact archetype purity is 0%; the deck mixes Train, Infinitrack, Cyber, Greed and Kaiju pieces
• No Side Deck

Critical choke points

• Gustav Max is the only route into the Gustav Rocket and Liebe bosses, and it is over the copy limit (1 legal copy)
• Train starters (Exceptional Schedule, Night Train, Urgent Schedule) are few copies each, so an opening without one stalls the Train route

Recommended changes

Evidence & confidence

• Verified: Illegal status: Gustav Max 3 copies vs legal 1 (Limited); Extra Deck count 16 vs maximum 15; Main Deck 59 cards, within 40-60; Ash Blossom 2 copies, legal (Semi-Limited); Exact archetype purity 0%; 75 off-archetype copies
• Inferred: Starter and brick probabilities computed from the Main Deck list; Strategy classification as Midrange with Toolbox secondary; Interaction and closing values from card text and role flags
• Provisional: Meta and format-fit scores (no dated metagame sample or tournament link)
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and match record absent No win-rate telemetry (going-first/second, matchup, brick and starter rates): these signals are Inferred or Unknown Meta Power is provisional unless a dated metagame sample is supplied No guides attached to the archetype Deck has no title and no Side Deck
