Fire King Deck #770317 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

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

• Primary strategy: Midrange
• Secondary strategies: Combo, Stun
• Format: master-duel

Legality

Main 41 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Fire King and Jurrac/Salamangreat Extra Deck boards (Garunix, Jurrac Meteor/Astero, Psychic End Punisher) converting a recovered field into lethal ATK; Fire King recursion from GY into repeated Special Summons and Link/Synchro chains
• Turn 1 (going first): Open on an archetype starter (Kirin, Courtier Ulcanix, Ponix, Megalo, Sanctuary or Island) and convert it into a Synchro/Link board, holding Ash Blossom and Dominus Impulse for the opponent's first answer
• Turn 2 (going second): Use hand traps (Ash Blossom, Droll and Lock Bird, Maxx C, Linkuriboh-line effects) to break the opponent's first board, then rebuild with GY recursion
• Recovery: Revive Fire King monsters from the GY through Fire King Island, Sanctuary and Circle of the Fire Kings, then rebuild through the Extra Deck
• After siding: No side deck is registered, so no post-side plan exists in this evidence

Why it scores here

The deck reliably opens a Fire King starter: the archetype core group (23 copies) has about a 0.989 chance of at least one copy in a 5-card opening hand, so the engine is accessible on paper (Inferred). Its interaction density is high, with 3 Ash Blossom, 3 Dominus Impulse, 2 Droll and Lock Bird, Maxx C and Crossout Designator, which helps it survive and contest the opponent's first board (Inferred from card text). Conversion into a win relies on Extra Deck boards with 2500 to 3500 ATK, but no recorded combo boards exist, so the ceiling and median are text-only inferences and are kept modest. Popularity and archetype usage do not earn points: the list is 42.9% exact-name archetype purity with 32 off-archetype copies, and the score is not an average of card scores. The Illegal status (3 copies of Kirin against a limit of 2) and the absence of a side deck cap the result, so this is a structural-only read.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 60, Going First ≈ 55, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: Illegal over-copy (Fire King High Avatar Kirin 3 vs 2) (-12). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 58; minus 12 Illegal over-copy modifier = 46; capped at 40 because the list is Illegal (theoretical/structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.99 · key two-card combo ≈ — · full-brick estimate ≈ 0.01 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Archetype core is dense (23 copies), so a starter is almost always in an opening hand (Inferred)
• Layered negation and removal: Ash Blossom x3, Dominus Impulse x3, Droll and Lock Bird x2, Maxx C (Verified text, Inferred strength)
• Extra Deck has high-ATK closers (Psychic End Punisher 3500, Garunix Eternity 3000)

Weaknesses

• Illegal copy limit: 3 copies of Fire King High Avatar Kirin against a Semi-Limited limit of 2 (Verified)
• No side deck, so no post-side adaptability (Verified)
• Low archetype purity (42.9%) with 32 off-archetype copies, which weakens engine coherence (Verified)
• No recorded combo boards, so ceiling and median are unverified (Verified gap)

Critical choke points

• Kirin over-limit: the deck cannot be played as submitted in Master Duel until one copy is removed
• Hand-trap dependence on Ash Blossom and Droll for going second

Recommended changes

Evidence & confidence

• Verified: Legality: Illegal, Kirin 3 copies vs limit 2; Main 41 / Extra 15 / Side 0 within size rules; Archetype purity 42.9% (24 of 56); No side deck; no combo boards; no tournament link
• Inferred: Starter accessibility 0.989 from archetype-core hypergeometric; Interaction layering and going-second hand-trap plan from card text; Extra Deck ceiling from card text
• Provisional: Meta Power (null); Format fit and matchup coverage (no dated meta); Going-second win rate (no win-rate telemetry)
• 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 side deck registered: post-side adaptability cannot be measured no win-rate telemetry in YGOVN for this deck Meta Power is Provisional unless a dated metagame sample is supplied
