Firewall Deck #761137 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 37/100 (±10 · Confidence: Low)

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

Legality

Main 56 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Link and Fusion boss monsters (Borrelshroud Dragon, Borrelend Dragon, Firewall Dragon Singularity, Borreload Fatalflare Dragon) built from Rokket and Borrel DARK Dragon engines, backed by hand-trap interaction.; Mulcharmy draw-punish turns: Mulcharmy Fuwalos and Mulcharmy Purulia draw cards when the opponent Summons while the deck controls no cards.
• Turn 1 (going first): Open Rokket Loader, Rokket Tracer, Rokket Barrage or Quick Launch to Special Summon a Rokket monster, search with Absorouter Dragon or Boot Sector Launch, then go to a Link Summon using DARK Dragon material. The hand-trap-heavy shell is not required on turn 1.
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre and Maxx C, Droll and Lock Bird, Solemn Judgment or Dominus Impulse to disrupt the opponent's Summons and spells, then rebuild through Rokket or Borrel material.
• Recovery: Rokket Tracer and Rokket Detonator can rebuild from the GY, and Triple Borrel Launch or Double Interlock can recur Dragons. Recovery depends on GY Dragons and Rokket monsters being present, which is not guaranteed.
• After siding: Not evaluable: no Side Deck is supplied.

Why it scores here

The score is computed on the deck as a system, not as an average of card scores. Consistency is moderate: three-copy Rokket starters give about a 25% chance of at least one in a five-card opening hand (Inferred), and the ten archetype-core copies give about 64%, so the deck usually has a starter but often opens with a dead or support-only hand. Interaction is the strongest area: nine hand traps plus Solemn, Mind Mirror Force, Dominus Impulse, Dimensional Barrier and Ash Blossom give broad, layered coverage that helps on the going-second side. The ceiling is high on paper through the 3500 ATK Link bosses, but no recorded boards exist, so floor and median output are unknown and scored conservatively. The deck contains a Forbidden card (Borreload Savage Dragon) and thirteen Limited cards, so it is illegal in OCG as built; it is therefore scored as theoretical/structural-only and capped low. Popularity and archetype-usage signals were not used to add points, and no post-side or matchup data exists.

Dimension scores

How the score was computed

Strategy profile: Midrange 85% / Stun 15% (primary Midrange; Stun-leaning interaction). Structural ≈ 51, Going First ≈ 50, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist exposure (-8); hard garnet burden (-2); engine conflicts (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); structural-only label because the deck is illegal: 0.80*51 + 0.20*40 = 48.8, then modifiers -12 = 36.8, rounded 37

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · 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

• Broad hand-trap and spell/trap negation suite that works on both turns
• Multiple independent starters (Rokket, Mulcharmy, Ash/Ghost Ogre) reduce single-card dependence
• Link-heavy Extra Deck with 3500 ATK boss options
• Compact-enough Main Deck with few level-0 dead slots

Weaknesses

• Illegal as built: Forbidden Borreload Savage Dragon and thirteen Limited cards
• No Side Deck, so post-side adaptation is impossible
• Engine split across several archetypes (Rokket, Borrel, Mulcharmy, PSY-Frame), lowering coherence
• High non-engine density raises brick risk on the going-first side

Critical choke points

• Rokket monster access (Rokket Loader, Tracer, Barrage, Absorouter) is required for most Link lines
• Borrel and DARK Dragon GY material for Link and Fusion bosses
• Hand traps are the main defense; a single unanswered Summon can end the turn

Recommended changes

Evidence & confidence

• Verified: Main 56, Extra 15, Side 0; Main and Extra within OCG size rules; Borreload Savage Dragon is Forbidden in OCG and is run once; Thirteen cards are Limited and two are Semi-Limited in the list; Card text for all listed cards is resolved
• Inferred: Starter access probabilities (hypergeometric, Main Deck only); Hand-trap interaction density and layering from card text; Link and Fusion boss ceiling from card text
• Provisional: Meta Power is null; no dated metagame sample; Matchup fit and post-side plans are unknown
• Data gaps: no combos supplied: floor, median and ceiling are text-only inference no tournament link: archetype meta-share and pilot match record absent no win-rate telemetry in YGOVN (going-first/second, matchup, brick/starter rates) Meta Power provisional unless a dated metagame sample is supplied no Side Deck supplied deck title is null; archetype label Firewall does not match the deck's dominant Rokket/Borrel engine
