Ursarctic Deck #774675 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 63/100 (±6 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Midrange, Synchro, Fusion
• Format: tcg

Legality

Main 46 / Extra 12 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Synchro boards from the Extra Deck (Ursarctic Septentrion, Grand Chariot, Polar Star, Swordsoul Chengying) built off Level 7+ Tribute fodder and Tuner-based summons.; Ultimate Flagship Ursatron Fusion, summoned by banishing Ursarctic Big Dipper and Drytron Fafnir after Ursarctic Drytron is used (single copy of each piece).
• Turn 1 (going first): Search via Ursarctic Departure and Ursarctic Quint Charge into a Level 7+ starter (Ursatron Alpha, Mikpolar, Miktanus, Mikbilis), Tribute-summon a second Ursarctic monster, then Synchro into a boss. Inferred from card text, no recorded boards.
• Turn 2 (going second): Four hand-trap-type cards (3x Infinite Impermanence, PSY-Framegear Gamma) plus PSY-Frame Driver and Epsilon/Delta special summons on opponent's Trap/Spell activation to negate and rebuild a board. Inferred.
• Recovery: Recursion from GY and banish (Lefty Driver, Ursarctic Departure, Ursarctic Quint Charge, Ursarctic Radiation shuffle) plus 16 searcher-text copies to refill hand.
• After siding: None. The deck runs no Side Deck, so there is no post-side plan.

Why it scores here

This Ursarctic list reliably opens into its engine: 16 searcher-text copies give P(at least one in a 5-card opening hand) of about 0.90 (Inferred), and the Level 7+ Tribute fodder density lets the Ursarctic monsters chain. Its conversion ceiling is high because the Extra Deck carries Septentrion, Grand Chariot, Chengying, and Flagship Ursatron, with destruction and banish effects in the text. The median is much less certain: no recorded boards exist, so the floor is text-only inference and is scored more conservatively. Interaction is layered through four hand-trap-type cards and Tuner specials, and the going-second hand-trap probability of about 0.44 is a real but imperfect plan. The score does not come from Ursarctic being a popular archetype, and the card scores were not averaged; the score reflects the system. The lack of a Side Deck and the single-copy Drytron and Flagship line cap the result.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 66.6, Going First ≈ 68, Going Second ≈ 64, Meta = provisional, Tournament Reliability ≈ 57. Modifiers: Unrecoverable single-copy choke point (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, no dated metagame sample) = 53.3 + 11.4 - 2 = 62.7, rounded to 63

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.9 · key two-card combo ≈ — · full-brick estimate ≈ 0.62 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Searcher density (16 copies) makes the engine reliably reachable in the opening hand.
• Extra Deck carries multiple boss Synchros with destruction and ATK scaling.
• Layered interaction: 4 hand-trap-type cards, Tuner-based hand summons, and removal text on 20 cards.
• Compact 46-card main with consistent 2-3 copy core (Archetype purity 62% exact name, broader archetype family coherent).

Weaknesses

• No Side Deck, so no post-side adaptation.
• Single-copy Drytron and Fafnir pieces gate Ultimate Flagship Ursatron.
• High Synchro and Tribute sequencing complexity for the pilot.
• No recorded combos, so the floor and median are text-only inference.

Critical choke points

• Ursarctic Drytron (1 copy) and Drytron Fafnir (1 copy) are required for the Flagship Ursatron line.
• Level 7+ hand fodder for Tribute summons depends on the 3-copy and 2-copy Ursarctic Level 7+ monsters being drawn.

Recommended changes

Evidence & confidence

• Verified: Legal: 46 main, 12 extra, 0 side; PSY-Framegear Gamma runs 1 copy of a Limited card (legal).; Card stats and text for the 21 main and 8 Extra-Deck distinct cards.; Archetype usage: Ultimate Bright Knight Ursatron Alpha and Drytron Fafnir at 50% inclusion each.
• Inferred: Opening-hand probabilities (hypergeometric, main deck only).; Engine conversion, interaction density and resilience from card text.; Going-second hand-trap plan and pilot complexity.
• Provisional: Matchup and format fit (D13) and meta power (null).; Side deck adaptability (D12) without a Side Deck.
• 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, going-second, matchup and brick rates are Inferred or Unknown. Usage statistics cover only 2 rows of the archetype. Meta Power is provisional without a dated metagame sample.
