Firewall Deck #773227 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 40/100 (±8 · Confidence: Low)

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

Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Link/Synchro/Xyz Cyberse board (Firewall Dragon Darkfluid, Accesscode Talker, Primathmech Alembertian) built from Ignister, Mathmech and Code Talker starters (Inferred); Hand-trap-protected pressure: disrupt the opponent's engine, then convert the Extra Deck summon (Inferred)
• Turn 1 (going first): Open a Cyberse starter (Pikari, Backup, Mulcharmy, Effect Veiler), search a Cynet/A.I. piece, and Link or Synchro into a Link-3+ board with protection from Ash Blossom or Ghost Ogre (Inferred)
• Turn 2 (going second): Use the six-card hand's hand traps (Infinite Impermanence, Effect Veiler, Nibiru, Droll & Lock Bird, Ghost Ogre) to stop the opponent's first board, then rebuild through the Extra Deck (Inferred)
• Recovery: Recurse Level 4 Cyberse monsters from the GY through Mathmech Circular, Backup and Achichi, and re-summon through the Link monsters (Inferred)
• After siding: Not evaluable: the side deck is empty (0 cards), so no post-side plan exists

Why it scores here

This OCG Firewall list is a multi-engine Cyberse build: Ignister, Mathmech, Code Talker and Firewall pieces share a Link/Synchro/Xyz Extra Deck, and the 22-copy archetype core opens at least one copy in 93% of five-card hands (Inferred from the hypergeometric table). Its interaction suite (19 hand traps, 17 negation-text cards, two Solemn cards, Harpie's Feather Duster) gives it the strongest dimension, so it scores well on end-board interaction and going-second disruption. Combo ceiling and median output are scored from card text only because the deck has no recorded boards, which keeps the ceiling and floor scores moderate and Inferred. The list is Illegal: three copies of Ash Blossom & Joyous Spring exceed the OCG Semi-Limited limit of two, so the score is capped, is theoretical and structural only, and does not reflect a legal tournament build. Popularity and archetype usage stats confirmed the list is real but did not add power, and the dimension scores were not averaged from individual card scores.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 54.6, Going First ≈ 56, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Illegal: copy-limit violation (-12). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 51.7, then Illegal copy-limit modifier -12 = 40 (structural-only, not a legal-deck score)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.93 · 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

• Layered interaction: 19 hand traps, 2 Solemn cards and Harpie's Feather Duster
• Large archetype-core presence (22 copies, ~0.93 open rate)
• Multiple searchers and GY recursion keep the engine alive

Weaknesses

• Illegal copy-limit violation (3x Ash Blossom & Joyous Spring vs OCG limit of 2)
• Very wide sub-archetype spread (2.9% exact-name purity; 68 off-archetype copies)
• No side deck, so no post-side adaptation

Critical choke points

• Cyberse Link/Synchro/Xyz chains depend on a small number of Link-3+ starters and boss monsters
• Ash Blossom is the single over-limit card: once the list is legal, one copy is removed and the interaction count falls

Recommended changes

Evidence & confidence

• Verified: Deck is Illegal: 3 copies of Ash Blossom & Joyous Spring vs OCG limit 2; Main 55 / Extra 15 / Side 0, within OCG size rules; Archetype core 22 copies with p_open_at_least_one_hand5 = 0.9318; Exact-name archetype purity 2.9%, 68 off-archetype copies
• Observed: No recorded boards (combos_evidence total 0); No tournament link (tournament_context unavailable)
• Inferred: Combo primary strategy from Link/Synchro/Xyz Cyberse engine and text; Interaction density high from role-tag counts and card text; Going-second value from hand-trap and negation text; Consistency estimate from hypergeometric draw table
• Provisional: Meta Power null; format fit (D13) 45 without dated metagame data
• Data gaps: no combos supplied: combo floor/median/ceiling is 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) Meta Power is Provisional without a dated metagame sample deck title is null and no side deck supplied
