Ice Barrier Deck #768405 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 31/100 (±8 · Confidence: Low)

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

Legality

Main 58 / Extra 15 / Side 0 — status: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Synchro boss monsters (Lancea, Graydle Dragon, Coral Dragon, Icejade Gymir, Trishula Zero) converting a board that the Ice Barrier hand traps and negations have already cleared; Ice Barrier Synchro and Xyz pressure from Stealth Kragen / Toadally Awesome once the opponent's engine is blanked
• Turn 1 (going first): Open a WATER tuner (Icejade Ran, Georgius, Hexa Spirit, Fishborg Harpooner) with a Level 4 non-tuner, Synchro into a boss, and hold a hand trap or Blizzard / Breakthrough Skill for the response
• Turn 2 (going second): Use the six-card hand (about 50% to contain a hand trap) to interrupt the opponent's first board with D.D. Crow, Skull Meister, Forbidden Chalice or Forbidden Lance, then rebuild through Mirror / Medallion / Winds Over the Ice Barrier searches
• Recovery: Recover through Ice Barrier searchers (Medallion, General Wayne, Toadally Awesome) and recursion (Freezing Chains, Winds Over the Ice Barrier GY banish)
• After siding: No side deck is run, so there is no post-side plan; any matchup adjustment is currently impossible without changing the main deck

Why it scores here

The deck is scored as a system, not as an average of its card scores, and its legality cap governs the result. Its Main Deck gives it real interaction: six hand traps and about 17 negation-text and 17 removal-text cards, and the Ice Barrier monsters add layered floodgate-style effects, which earn the end-board and going-second credit. Engine access is the weak point: the Ice Barrier core is only 25 of 58 exact-name copies (34%), the archetype-core group has a 31% chance of at least one copy in a five-card opening hand, and the 4-copy archetype core is well below the usage-stat core list, so consistency is modest and largely Inferred. Synchro boss depth and Extra Deck coverage are real but not verified by any recorded board, and no combos or win-rate data exist, so the ceiling and median are text-only estimates. Popularity or archetype usage did not earn points, and the deck is capped because Trishula, Dragon of the Ice Barrier is Forbidden in OCG with one copy; the result is therefore a structural-only read, not a normal final contextual score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 45, Going First ≈ 45, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: Banlist exposure (Forbidden card in format) (-12). Final formula: Illegal-deck cap: 0.80*Structural(45) + 0.20*TournamentReliability(35) = 43, then banlist exposure modifier -12 = 31; Meta provisional

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.31 · 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 interaction: 6 hand traps and about 17 negation-text plus 17 removal-text cards
• Layered Ice Barrier monsters (Mirror, Revealer, Warlock, Georgius, Speaker, Hexa) add floodgate-style pressure once the archetype is live
• Synchro boss suite (Lancea, Graydle Dragon, Icejade Gymir, Trishula Zero) gives real closing power

Weaknesses

• Illegal in its format: Trishula, Dragon of the Ice Barrier is Forbidden in OCG and is run one copy
• No side deck, so there is no post-side adjustment
• Low exact-archetype purity (34%) with many generic and sub-archetype slots
• Engine access depends on a 4-copy core that is present in only about 31% of opening hands

Critical choke points

• Trishula, Dragon of the Ice Barrier (Forbidden) occupies a Synchro slot and must be removed to make the list legal
• Ice Barrier Synchro depth depends on WATER tuners that are single-copy or 2-copy in the Extra Deck

Recommended changes

Evidence & confidence

• Verified: Trishula, Dragon of the Ice Barrier is Forbidden in OCG and run 1 copy, making the deck Illegal; Main 58 and Extra 15 are within size rules; Side 0 is allowed; Composition: 28 distinct Main cards, 14 distinct Extra cards, 12 Synchro, 3 Xyz; Usage stats show 2 of 14 archetype core cards present (14.3%)
• Inferred: Engine consistency P(>=1 core in 5) = 0.31 from hypergeometric draw; Interaction quality from 6 hand traps and 17 negation-text cards; Going-second hand-trap coverage P = 0.50
• Provisional: Meta power is null; no dated metagame sample; Format fit is provisional without tournament context
• 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 rates) No side deck supplied, so post-side performance is unknown Meta Power is Provisional unless a dated metagame sample is supplied
