Ursarctic Deck #771668 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 32/100 (±8 · Confidence: Medium)

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

Legality

Main 53 / Extra 17 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Board pressure from high-ATK Ritual, Xyz and Link beaters (Drytron Meteonis DA Draconids 5000 ATK, K9-X Ripper/M 3100 piercing, Divine Arsenal AA-ZEUS 3000, Underworld Goddess 3000) after a Drytron or K9 engine starts; Attrition through hand traps and removal text (Ash Blossom, Infinite Impermanence, Ghost Belle, Nibiru, Droll & Lock Bird) that stalls the opponent's engine
• Turn 1 (going first): Open a Drytron or K9 starter, search with the engine searchers, and Ritual or Xyz into a single beater; the Ursarctic core that would make this a coherent plan is almost entirely absent
• Turn 2 (going second): Hold hand traps (13 in Main) to negate the opponent's first engine activation, then convert with a Ritual or Xyz beater; this is the strongest use of the list
• Recovery: Recursion through Drytron Gamma/Zeta/Alpha Special Summons from the GY and Mulcharmy Fuwalos draw effects; depends on the draw roll, since no single recovery line is reliable
• After siding: Not available: the Side Deck is empty, so no post-side adaptation exists and the deck cannot be re-tuned between games

Why it scores here

The deck is an illegal OCG list: its Extra Deck has 17 cards against a limit of 15, and Ash Blossom and K9-17 Izuna are each run three times against a Semi-Limited limit of two. Its consistency is weak. Three sub-archetypes (Drytron, K9, and a small Ursarctic contingent) share the list, and only one of the 15 Ursarctic core cards is present, so the archetype's own engine is largely missing. Its strongest feature is interaction: 13 hand traps and 16 negation-text cards give a meaningful going-second plan, which pushes the going-second estimate above the going-first estimate. Its closing power comes from several high-ATK Ritual, Xyz and Link beaters, but there is no combo data to show how often they are reached. The score is capped low because the list is illegal, and the scoring is based on the system, not on an average of card scores. Archetype popularity was not used: the usage data shows only 1 of 15 core cards present, so it earns no credit.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 46, Going First ≈ 40, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: Illegal list (size and copy-limit violations) (-9); Engine conflicts across sub-archetypes (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 43.8, then illegal-list cap and engine-conflict modifiers applied = 32

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.26 · 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

• Interaction density: 13 hand traps and 16 negation-text cards give a real going-second plan
• High-ATK closers (Draconids 5000, K9-X Ripper/M 3100 piercing, Divine Arsenal 3000) can end games
• Multiple searcher-capable cards give a high chance of finding a playable starter by turn 2

Weaknesses

• Illegal list: Extra Deck over the limit and two cards over their copy limit
• No Side Deck, so no post-side adaptation
• Split engine: three sub-archetypes with 1.4% exact-name purity and only 1 of 15 Ursarctic core cards present
• High non-engine count (30 hand traps and tech cards in Main) increases brick and conflict risk

Critical choke points

• The Drytron or K9 starter must be live by turn 2; a single starter has about a 0.26 chance to appear in the opening hand
• Hand-trap coverage depends on the opponent's first activation, so it is unreliable on the going-first turn

Recommended changes

Evidence & confidence

• Verified: Main Deck size is 53, within the OCG range of 40 to 60; Extra Deck size is 17, above the OCG maximum of 15; Ash Blossom & Joyous Spring and K9-17 Izuna are each run three times against a Semi-Limited limit of two; Side Deck is empty; Exact-name archetype purity is 1.4%; 13 hand traps and 17 tech cards in Main; Only 1 of 15 Ursarctic core cards is present
• Inferred: Going-second plan is stronger than going-first because of hand-trap coverage (P ≥ 1 in a 6-card hand ≈ 0.83); Engine consistency is low because the engine splits across three sub-archetypes; Brick risk is high because of the non-engine count; Closing power comes from high-ATK Ritual, Xyz and Link beaters; Interaction quality is high by card-text read
• Provisional: Format fit and matchup coverage, pending a dated meta sample or tournament link
• Data gaps: No combos supplied, so the combo floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and per-pilot match records are absent No win-rate telemetry exists (going-first/second, matchup, brick and starter rates) Side Deck is empty, so post-side adaptation cannot be scored Meta Power is provisional without a dated metagame sample
