Ursarctic Deck #770537 — Yu-Gi-Oh! TCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 40/100 (±10 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Midrange, Stun
• Format: tcg

Legality

Main 46 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Drytron Ritual boss (Meteonis DA Draconids 5000 ATK / Meteonis Quadrantids 4000 ATK) summoned through Meteonis Drytron, backed by the Drytron Nu II / Zeta / Alpha / Gamma engine chain; Extra Deck Link and Xyz beats (Underworld Goddess, Worldsea Dragon Zealantis, Divine Arsenal AA-ZEUS) once the board is stable
• Turn 1 (going first): Open on a Drytron engine monster from hand (Nu II, Zeta Aldhibah, Alpha Thuban or Gamma Eltanin) to search the next Drytron piece, then move into a Meteonis Drytron ritual or Xyz extension
• Turn 2 (going second): Use the 9 hand traps (Ash Blossom, Ghost Ogre & Snow Rabbit, Effect Veiler) and Dark Ruler No More to break the opponent's first board, then rebuild through the Drytron engine
• Recovery: Drytron Fafnir and Meteonis Drytron recover Drytron spells and monsters from the GY; Drytron Mu Beta Fafnir (2 copies) is the only Extra Deck recursion route
• After siding: Not evaluable: the deck has no Side Deck, so there is no post-side plan

Why it scores here

The deck is a Drytron-engine build rather than a true Ursarctic deck: only one card carries the exact Ursarctic name, while 25 cards are Drytron and 24 are generic. Its searcher density is high (about 96% chance of at least one searcher in an opening 5), so the engine usually comes online early, and its 16 negation and 12 removal texts give it real interaction on the system. Its ceiling comes from the Ritual bosses (Meteonis DA Draconids, Meteonis Quadrantids) and Extra Deck Links and Xyz, but the recorded combo data is empty, so floor and median are inferred from text only and kept low. Structural power is about 59, but the deck is Illegal because it runs 3 copies of Ash Blossom & Joyous Spring against a limit of 2, so it is capped at 40 as a theoretical, structural-only read. Popularity was not used, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 59, Going First ≈ 60, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: illegal-list cap (-12); no side deck (-2); archetype label mismatch (0). Final formula: Illegal cap: normal blend 0.80*59 + 0.20*52 = about 58 is replaced by a hard cap of 40 (theoretical/structural-only). Meta provisional.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.96 · 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

• Searcher density: 21 searcher-text cards give a high chance of a live engine on turn 1
• Interaction density: 9 hand traps and 16 negation texts across Ash Blossom, Ghost Ogre, Effect Veiler, Dark Ruler No More and Drytron Fafnir
• Strong boss ceiling: Meteonis DA Draconids (5000 ATK), Meteonis Quadrantids (4000 ATK), Underworld Goddess (3000 ATK), AA-ZEUS (3000 ATK)

Weaknesses

• Illegal list: Ash Blossom & Joyous Spring at 3 copies against a limit of 2
• No Side Deck (0 cards), so no post-side adaptability
• Exact-archetype purity is 1.6%; the deck is a Drytron build labeled Ursarctic
• No recorded combos, no tournament data, and no win-rate telemetry

Critical choke points

• Drytron engine needs a Drytron monster already on the field, so an opponent's early hand trap or removal stops the whole chain
• Meteonis Drytron is the only route to the Ritual bosses (2 copies)

Recommended changes

Evidence & confidence

• Verified: Legality: Illegal, Ash Blossom & Joyous Spring at 3 copies against a limit of 2; Main count 46 (within 40 to 60); Extra count 15 (within 0 to 15); Side count 0; Copy histogram: 10 single, 3 double, 10 triple; Exact-archetype purity 1.6%; Drytron spread 25, generic 24
• Inferred: Engine consistency from hypergeometric odds and searcher density; Interaction quality from negation and removal text; Ceiling from Ritual and Xyz boss text; Pilotability from sequencing complexity
• Provisional: Floor and median output (no combos); Format fit and matchup coverage (no meta sample); Going-first and going-second split
• 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/second, matchup, brick/starter/OTK rates) Meta Power is Provisional unless a dated metagame sample is supplied Deck title is null; no Side Deck present
