Gouki Deck #770168 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 40/100 (±10 · Confidence: Low)

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

Legality

Main 40 / Extra 15 / Side 0 — status: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Gouki link and fusion boards (The Tyrant Ogre, The Master Ogre, The Powerload Ogre, Virus Berserker) that negate or destroy opposing cards and close through large ATK.; Gouki Dragon Ogre synchro and The Great Ogre field-wipe followups once the Gouki Link base is established.
• Turn 1 (going first): Normal Summon Gouki Suprex or Machine Suprex and use their GY and Normal Summon triggers to add or summon Gouki pieces, reaching a Link-3 or Link-4 Gouki board while holding Ash or Veiler for the opponent's first response.
• Turn 2 (going second): Hold the 6-card hand's hand traps (Ash, Effect Veiler, Ghost Ogre, Infinite Impermanence) to answer the opponent's first board, then rebuild through Headbatt and Re-Match recursion into Link Summons.
• Recovery: Gouki GY-send effects (Suprex, Machine Suprex, Riscorpio, Moonsault, Iron Claw) each add a Gouki from the Deck, so a single removal or negation leaves a searched follow-up in hand.
• After siding: No side deck is listed, so there is no post-side plan. Structurally the deck cannot adjust across games in a best-of-3 event.

Why it scores here

The score is structural only because the list is illegal: Ash Blossom & Joyous Spring runs 3 copies against an OCG limit of 2. Within that, the deck's consistency comes from a dense Gouki core (20 copies, about 0.98 chance of at least one in a 5-card opening, Inferred) and 21 searcher-text cards that chain back into the engine. Its interaction layer is broad, with about 12 hand-trap-type cards and 9 negation texts, which lifts the endboard and resilience scores. Its closing power rests on several 2600 to 3500 ATK link and fusion monsters in the Extra Deck. The score does not come from Gouki being a popular archetype, and it is not an average of card scores. Several factors pull it down: the Extra Deck mixes Firewall, Codebreaker, G Golem, P, and Kuriboh pieces, 30 of 40 Main Deck copies are off-archetype by exact name, and the deck has no side deck, so it cannot adapt between games.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 59, Going First ≈ 62, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Banlist exposure (-8); Engine conflicts (-4); Illegal cap (-5). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*59 + 0.20*50 - 12 = 45.2, then capped to 40 because the list is Illegal (theoretical, structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.98 · 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 Gouki core with 21 searcher-text cards and GY-send recursion gives strong resource regeneration
• Layered hand traps and negations (about 12 and 9) give interaction on both turns
• Extra Deck link and fusion threats reach 2600 to 3500 ATK for closing power

Weaknesses

• Illegal list: Ash Blossom & Joyous Spring is run at 3 copies against an OCG limit of 2
• No side deck, so there is no post-side adaptation
• Off-archetype density (30 of 40 Main Deck copies) and a mixed Extra Deck lower coherence
• Only 12 of 25 usage-core cards are present; Gouki Dragon Ogre, The Tyrant Ogre, and Droll & Lock Bird are missing

Critical choke points

• Ash Blossom & Joyous Spring's over-limit count makes the list illegal until one copy is removed
• The Gouki Link chain depends on Suprex and Machine Suprex as early Normal Summon starters
• Hand-trap response depends on the opponent acting first, leaving a reactive gap if a hand has no starter

Recommended changes

Evidence & confidence

• Verified: Main Deck is 40 cards, Extra Deck is 15, Side Deck is 0; sizes are legal for OCG; Ash Blossom & Joyous Spring runs 3 copies against an OCG Semi-Limited maximum of 2, so the list is Illegal; Exact-name purity is 45.5 percent (25 of 55 copies are Gouki); 12 of 25 usage-core cards are present
• Observed: No parseable combo boards were recorded for this deck
• Inferred: Probability of at least one Gouki core card in a 5-card opening is about 0.98, a hypergeometric estimate; Hand-trap density and negation text give layered interaction on the endboard; Gouki GY-send recursion gives redundant routes after one interruption; Going-second hand-trap coverage is about 0.90 for at least one in a 6-card hand
• Provisional: Meta Power is null; no dated metagame sample or tournament link exists; Format fit (D13) is a neutral placeholder pending a dated sample
• Data gaps: No combos supplied, so combo floor, median, and ceiling are text-only inference No tournament link, so archetype meta-share and pilot match record are absent No win-rate telemetry exists for going-first, going-second, matchups, or brick and starter rates Meta Power is provisional unless a dated metagame sample is supplied No side deck is listed, so post-side scoring is absent
