Ice Barrier Deck #755970 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 5 violation(s).

Identity & game plan

• Win condition: Synchro and Link boards built from Ice Barrier and Mulcharmy/Icejade draw-and-summon chains, closing with 2700-3300 ATK Synchro monsters (Inferred); Hand-trap-protected Synchro setups that go through a single unanswered negate or removal window
• Turn 1 (going first): Open a Ice Barrier starter (Revealer, Georgius, Speaker or Prior) and extend into a Synchro or Link; Mulcharmy draws only work when the field is empty, which limits the turn-1 line
• Turn 2 (going second): Hold Ash Blossom, Droll, Ghost Ogre and Solemn to answer the opponent's first starter, then rebuild with Ice Barrier summons on the following turn
• Recovery: Ice Barrier monsters recurse from the GY (Georgius, Prior, Freezing Chains, Winds Over the Ice Barrier) to rebuild the board after a disruption
• After siding: Not evaluable: the deck has no Side Deck, so no post-side plan exists

Why it scores here

The list reliably opens an Ice Barrier starter in most hands (archetype core group P(at least one in a 5-card hand) about 0.94, Inferred), so the engine is accessible on turn 1 or 2. Nine hand traps and about 16 negation-text cards give the deck layered interaction, which earned the interaction and going-second scores. Conversion and median output could not be measured because no recorded boards exist, so those scores rest on text reads and are Inferred. Brick risk is high: 21 of 55 Main Deck cards are generic Level 0 spells and traps, and only about 31 percent of copies are exact-name Ice Barrier cards, which pulls down consistency and deck efficiency. The score is capped low because the list is illegal: Called by the Grave, Triple Tactics Talent and two Trishula, Dragon of the Ice Barrier are Forbidden in OCG, Ash Blossom is over the Semi-Limited limit, and Droll is over the Limited limit. The score was not built from averaging card scores or from the archetype's popularity.

Dimension scores

How the score was computed

Strategy profile: Midrange primary with Stun-style interaction weighting; the Midrange profile was used for the structural score because it fits the summon engine plus hand-trap mix. Structural ≈ 53, Going First ≈ 52, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-8); engine_conflicts (-4). Final formula: No reliable metagame: 0.80*Structural(53) + 0.20*TournamentReliability(45) + ContextModifiers(-12) = 39, then capped at 30 because the deck is Illegal; the result is theoretical/structural only

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.94 · key two-card combo ≈ — · full-brick estimate ≈ 0.06 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense hand-trap and negation coverage (9 hand traps, about 16 negation-text cards)
• High archetype-core access: P(at least one core card in opening hand) about 0.94
• Multiple independent Ice Barrier starters and GY recursion give alternate lines
• High-ATK Extra Deck closers (Lancea 3300, Dragite 3000, Gymir 3000)

Weaknesses

• Illegal as built: 3 Forbidden copies, 1 Forbidden spell, 2 over-limit Semi-Limited/Limited cards
• Low archetype purity (31.4 percent exact-name) with 21 Level 0 generic spells and traps
• No Side Deck, so no post-side adaptation
• Mulcharmy empty-field conditions conflict with the Ice Barrier board plan

Critical choke points

• Extra Deck Synchro summon requires a Tuner, and the Tuner pool is thin once the Forbidden Trishula copies are removed
• Going-first turn-1 plan depends on a single Ice Barrier starter being drawn

Recommended changes

Evidence & confidence

• Verified: Legality violations and banlist statuses (OCG); Card text and ATK/DEF values for listed cards; Copy histogram and Main/Extra counts (55/15/0); Archetype purity 31.4 percent
• Observed: Usage stats show the Ice Barrier core is real and accessible (21 archetype stat rows)
• Inferred: Starter access about 0.94 and brick rate about 0.058 (hypergeometric proxy); Interaction density from negation-text reads; Going-first and going-second estimates
• Provisional: Meta Power (null, no dated meta sample); Matchup and format fit
• Data gaps: No combos supplied (combos_evidence.total_combos is 0): floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate or matchup telemetry: going-first and going-second estimates are Inferred Meta Power is Provisional unless a dated metagame sample is supplied usage_statistics.missing_core is inconsistent with the cards array: Icejade Gymir Aegirine, Swordsoul Chengying, Trishula Zero and Adamancipator Dragite appear in the deck's cards list but are flagged missing and in_this_deck false; treated the cards array as source of truth Deck title is null, so the deck name cannot be cross-checked
