Ice Barrier Deck #775263 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 29/100 (±6 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Ashtra and Azamina synchro/fusion boss (Ashtraja Susanoo 3300 ATK, Ashtraya Mikumari-no-Mikoto 3000 ATK, Ekhajar 3000 ATK) summoned after a hand-trap or Solemn-protected setup; Stardust Dragon and Ruddy Rose Dragon as extra-deck threats; Diabellstar and Azamina Sol Erysichthon as fusion/synchro follow-ups
• Turn 1 (going first): Open a hand with a searcher (Ashtrashen, Deception of the Sinful Spoils, Mikumari) plus a face-down trap, then set up a Solemn or Dimensional Barrier stop and a synchro boss; no reliable turn-1 board is evidenced
• Turn 2 (going second): Use hand traps (Infinite Impermanence, Ash Blossom, Droll & Lock Bird, Maxx C, Ghost Ogre) to answer the first summon, then recover with Ashtra revival and a synchro boss
• Recovery: Ashtra GY-revival spells and Ashtrashen searches to rebuild a boss from the GY after a hand-trap spends the starter
• After siding: Not evaluable: the deck runs no side deck (side_count 0), so there is no post-side plan

Why it scores here

The deck is scored as a system, not as an average of its cards. It is illegal in OCG: three Forbidden copies (Snake-Eye, Azamina Ilia Silvia, Baronne de Fleur) make the list invalid, so the score is a structural estimate capped low and labelled theoretical. Its interaction suite is the strongest signal: about 26 negation-text cards, 22 removal-text cards, and 9 hand traps give it real end-board and response density (Inferred from card text). Consistency is weak. The Ice Barrier core is nearly absent (3 of 20 usage-core cards, 1.4% exact-name purity), and 69 of 81 archetype-tagged copies belong to other sub-archetypes (Ashtra, Solemn, Azamina, Stardust), so the engines are only loosely connected. The P(at least one 3-copy card in a 5-card opening hand) is about 0.25, and no combo boards are recorded, so the floor and ceiling are text-only inferences. Popularity and archetype usage were not used to raise the score.

Dimension scores

How the score was computed

Strategy profile: Stun primary, Toolbox secondary (structural weights from the Stun profile). Structural ≈ 40, Going First ≈ 37, Going Second ≈ 42, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist_exposure (-8); engine_conflicts (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional); theoretical/structural-only because the list is Illegal, capped low

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · 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

• Dense negation and removal text (26 negation / 22 removal cards) with 9 hand traps gives real interaction layering
• High-ATK synchro and fusion closers (Ashtraja Susanoo 3300, Ashtraya Mikumari-no-Mikoto 3000, Ekhajar 3000)
• Going-second hand-trap coverage: P(>=1 hand trap in hand of 6) = 0.68

Weaknesses

• Illegal in OCG: three Forbidden copies plus the list cannot be played as built
• Ice Barrier core largely absent (3 of 20 usage-core cards; 1.4% exact-name purity)
• No side deck, so there is no post-side adaptation
• Many level-0 non-monsters (34) and 29 distinct main cards reduce compactness and raise brick risk

Critical choke points

• Ashtra summons need a face-down card, so the opening hand depends on setting a card
• Hand-trap density is needed on going second; a single hand-trap shortage leaves the boss line unprotected

Recommended changes

Evidence & confidence

• Verified: Legality: 55 Main / 15 Extra / 0 Side; 3 Forbidden copies over limit (Snake-Eye, Azamina Ilia Silvia, Baronne de Fleur); Card text and stats for the listed cards; usage stats: 3 of 20 core cards present; Composition: 21 Trap, 17 Effect, 13 Spell main cards; 12 Synchro and 3 Fusion in Extra
• Inferred: Consistency estimates from hypergeometric draws (P(>=1 3-copy card in hand of 5) = 0.25); Interaction density (26 negation, 22 removal, 9 hand traps) read from card text; Turn-1 and turn-2 plans and the going-second plan
• Provisional: Meta Power (null): no dated metagame sample supplied; Matchup fit (D13) and tournament reliability: no tournament link
• Data gaps: No combos supplied: combo floor, median and ceiling are text-only inferences No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry (going-first/second, matchup, brick and starter rates) No side deck, so D12 post-side performance cannot be assessed Meta Power is provisional unless a dated metagame sample is supplied
