Icejade Deck #758906 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 20/100 (±10 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Synchro and Xyz boards (Poseidra Abyss, Icejade Gymir Aegirine, Swordsoul Supreme Sovereign - Chengying, Abysstrite) built off the Atlantis, Umi and Atlantean searcher chain; Link boards (Azure Ocean Dragon Lord - Neo-Daedalus Rage, Levia-Dragoon - Daedalus, Mermail Abyssalacia) that recycle the GY
• Turn 1 (going first): Search with Neptabyss, Levia-Dragon - Daedalus or Poseidra, then convert into a Level 7 Synchro or Xyz, keeping Ash Blossom and Maxx C up as interaction
• Turn 2 (going second): Open the 6-card hand with hand traps (Ash Blossom, Droll and Lock Bird, Maxx C, Infinite Impermanence) to slow the opponent, then rebuild from searchers
• Recovery: Searcher-heavy Atlantean and Umi text (19 searcher hints) gives several rebuild routes, but no recorded boards confirm any of them
• After siding: Not evaluable: the deck has no Side Deck, so there is no post-side plan

Why it scores here

This list is Illegal: it runs 2 copies of Bahamut Shark, which is Forbidden in OCG, so the score is capped and treated as structural only. Its searcher density (19 search hints, about 97% chance of at least one searcher in a 5-card hand) gives it a fairly reliable start, but the 40 main-deck cards span Atlantis, Atlantean, Umi, Daedalus, Abyss-, Mermail, Swordsoul and Marincess, with only 2 exact Icejade cards, so the engine is loosely connected. Interaction is the strongest area: 12 negation and 11 removal hints plus 5 hand traps give it good answers both going first and going second. No recorded boards exist, so conversion and floor/median are text-only inferences and score low. The deck has no Side Deck, which caps its adaptability and tournament reliability. Score comes from consistency, interaction and the Extra Deck on the system, not from averaging card scores, and popularity was not used as evidence of power.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 45, Going First ≈ 42, Going Second ≈ 46, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-12); illegal-list cap (-11). Final formula: Illegal list: normal formula 0.80*Structural(45) + 0.20*TournamentReliability(35) = 43, then banlist-exposure modifier -12 gives 31, then capped to 20 as a theoretical-only score (Meta provisional, null)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · 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 searcher text (19 hints) gives a high chance of finding a starter in the opening hand
• Strong interaction suite: 12 negation and 11 removal hints, plus 5 hand traps for both going first and second
• Several high-ATK Extra Deck bosses (2900 to 3000 ATK) give closing power

Weaknesses

• Illegal list: Bahamut Shark is Forbidden and run at 2 copies
• Loose engine: only 2 of 40 main-deck copies match the Icejade name exactly, and the rest spread across Atlantis, Atlantean, Umi, Daedalus and others
• No Side Deck, so there is no post-side adaptation
• No recorded boards, so conversion and floor claims are unmeasured

Critical choke points

• Atlantis, City of the Sea Dragon (1 copy) is the field spell tying the Umi and Atlantean text together
• Searcher chain depends on Neptabyss and Levia-Dragon - Daedalus being live, and both are 2-copy cards

Recommended changes

Evidence & confidence

• Verified: Bahamut Shark is Forbidden in OCG and is run at 2 copies, which is the legality violation; Main deck is 40 cards, Extra Deck 15, Side Deck 0; 12 negation, 11 removal and 5 hand-trap text hints, 19 searcher hints; Exact archetype purity is 3.6%: 2 of 55 copies match the Icejade name
• Inferred: Structural engine consistency from the searcher density and starter probabilities; Interaction quality from text hints and hand-trap count; Going-first and going-second splits from composition, not from play data
• Provisional: Meta and format fit (D13): no tournament link and no dated metagame sample
• 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 exists in YGOVN, so going-first, going-second and matchup claims are Inferred or Unknown Meta Power is provisional unless a dated metagame sample is supplied deck title is null, so the deck is identified by id and archetype only no Side Deck supplied, so post-side evaluation is not possible
