Firewall Deck #768705 — 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 56 / Extra 14 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Link-summon Link-3 to Link-5 Cyberse monsters (Code Talker, Firewall, @Ignister shells) into 2300-3000 ATK boards such as Firewall Dragon Darkfluid - Neo Tempest Terahertz and Decode Talker Integration (Inferred from card text); Stun the opponent's board with hand traps and negations (Ash Blossom, Infinite Impermanence, Effect Veiler, Evenly Matched) and win on the resulting unanswered Link board (Inferred)
• Turn 1 (going first): Opening hand with a searcher (Lady Debug, Backup @Ignister, Cynet Mining) to reach a 2-card Link bootstrap, keeping Ash Blossom or Infinite Impermanence for the opponent's first interaction (Inferred)
• Turn 2 (going second): Six-card hand with a hand trap (P at least one hand trap in hand 6 is about 0.88) to negate the opponent's first board-setting effect, then rebuild through Code Talker and Firewall searchers (Inferred)
• Recovery: Firewall Defenser and Firewall Guardian send-to-GY effects re-Special Summon Firewall monsters from the Deck; Code Generator and Cynet Codec re-search Cyberse monsters (Inferred from card text)
• After siding: Not supported by the list: the deck has 0 side cards, so no post-side plan can be evaluated

Why it scores here

The deck reliably opens a searcher: the probability of at least one searcher-text card in a 5-card opening hand is about 0.90, and at least one archetype-core card is about 0.78 (Inferred from the hypergeometric table). Its engine is split across Firewall, Code Talker, @Ignister and generic Cyberse cards, so the link-into-board conversion is plausible but not dependably coherent; the archetype purity is only 5.7% exact-name. Interaction is the strongest part of the list, with 16 hand-trap or negation cards and roughly 88% odds of one in a going-second hand. No combo boards or tournament results exist, so the floor and median are inferred from text only and kept low, and the score does not come from averaging card scores or from the Firewall archetype's popularity. The list is illegal because it runs 3 Ash Blossom & Joyous Spring against a limit of 2, and it has no side deck, so it is capped and scored as a structural-only evaluation.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 49, Going First ≈ 48, Going Second ≈ 54, Meta = provisional, Tournament Reliability ≈ 42. Modifiers: Banlist / copy-limit exposure (-8); No post-side plan (-4); Illegal cap (-6). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*49 + 0.20*42 - 12 = 35.6, then capped to 30 because the list is Illegal (copy limit exceeded)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.9 · 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 (20 searcher-text cards) gives about a 0.90 chance of a searcher in the opening hand
• Layered interaction with 16 hand-trap or negation cards and about 0.88 odds of a hand trap in a going-second hand
• Extra Deck of 14 covers the Link-1 to Link-5 range with 2300-3000 ATK boards

Weaknesses

• Illegal as built: 3 copies of Ash Blossom & Joyous Spring against an OCG limit of 2
• Low archetype purity (5.7% exact name); the engine is split across Code Talker, Firewall, @Ignister and generic Cyberse cards
• No side deck, so no post-side plan and no best-of-3 adaptability
• No combo, tournament or win-rate evidence, so the floor and median are unmeasured

Critical choke points

• The Link-3 to Link-5 bootstrap depends on a small set of 2-card starters; a single hand disruption can leave no Link route (Inferred)
• Going-first hands without a searcher or a Link starter have no functional plan (Inferred)

Recommended changes

Evidence & confidence

• Verified: Legality: 56 main, 14 extra, 0 side; Ash Blossom & Joyous Spring 3 copies against a Semi-Limited limit of 2 (Illegal); Composition: 16 hand traps, 21 tech, 0 floodgate, 13 Link and 1 Fusion Extra cards, archetype purity 5.7%; Usage statistics: 8 of 25 core cards present (32%)
• Inferred: Opening-hand probabilities for searchers (0.90), archetype core (0.78) and hand traps going second (0.88); Engine and Link-route reads from card text; Interaction density (Ash, Infinite Impermanence, Evenly Matched, Effect Veiler) and recursion routes
• Provisional: Meta Power and format fit (no dated metagame sample; no tournament link)
• 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 and starter rates) Meta Power is Provisional unless a dated metagame sample is supplied Deck has no title and no side deck
