Phantom Knights Deck #763045 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Medium)

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

Legality

Main 40 / Extra 21 / Side 0 — status: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Link/Xyz boss monsters from the Extra Deck (Firewall Dragon Singularity 3500 ATK, Underworld Goddess 3000 ATK, Borreload Savage Dragon 3000 ATK, Super Starslayer TY-PHON 2900 ATK) once a Link or Xyz base is established; Ritual Cyberse Sage and Code Igniter searching and summoning Cyberse and Link bodies; Wind-Up Zenmaity Xyz pressure
• Turn 1 (going first): Open a Wind-Up or Speedroid starter (Wind-Up Shark, Wind-Up Rat, Wind-Up Magician, Speedroid Terrortop) and extend into a Link-2/Link-3 base; keep Ash Blossom or Red Reboot for the first opposing interaction
• Turn 2 (going second): Hand-trap the opponent's first board (Ash Blossom, Red Reboot, Evenly Matched) and rebuild through Wind-Up Magician and Doomed Soleret; use Underworld Goddess or Herald of the Arc Light to negate an established board
• Recovery: Wind-Up Zenmaintenance and Edge Imp Sabres recur from the GY; Wind-Up Rabbit banishes a Wind-Up monster to dodge removal; Speedroid Taketomborg and Doomed Soleret reload the hand
• After siding: Not applicable: Master Duel has no side deck (side_count 0)

Why it scores here

The list is Illegal in Master Duel because its Extra Deck holds 21 cards against a maximum of 15, so the score is a theoretical, structural-only read capped low and not a normal Final Contextual score. The Main Deck is legal on copy limits (Foolish Burial, Herald of the Arc Light, Monster Reborn and Reinforcement of the Army each run 1 copy at their Limited cap, and Red Reboot runs 1 of 2) and has seven 3-copy monster names that give real starter density, so the engines open often (Inferred). The deck is not a coherent Phantom Knights build: exact-name purity is 4 of 61 copies and most of the archetype core is absent, so the engines are three or four unrelated sub-archetypes (Wind-Up, Cyber/Code Talker, Roid, Ignister) that connect only loosely. Its interaction density (about nine negation texts, several 1-of hand traps and negates in the Extra Deck) is the strongest part and earns D7 and D8, while the Extra Deck overflow and the many situational spells cost D2, D10 and D11. Archetype popularity and usage statistics confirm the list is real but did not add points, no combo boards were recorded so floor and median are unknown, and the score was not produced by averaging individual card scores.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 56, Going First ≈ 56, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: Illegal size cap (-18); Engine conflict (-4); Banlist exposure (-3). Final formula: Illegal cap applied: 0.80*Structural(56) + 0.20*TournamentReliability(50) + Modifiers(-7) = 48 pre-cap; capped to 30 as a theoretical/structural-only score because the Extra Deck exceeds the Master Duel maximum

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.92 · 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

• Seven 3-copy monster names give broad starter access on either turn order
• Dense negation and removal coverage across Main and Extra Decks, including Underworld Goddess, Herald and Accesscode Talker
• High-ATK Link and Xyz finishers (Firewall Singularity 3500, Underworld Goddess 3000, Borreload 3000)
• Multiple GY recursion routes (Zenmaintenance, Edge Imp Sabres, Taketomborg) support grind

Weaknesses

• Illegal Extra Deck size (21 vs 15)
• Incoherent archetype identity: only 4 of 61 copies are exact Phantom Knights
• Many situational or 1-of spells that brick or go dead
• No recorded combo boards, so consistency and output claims rest on inference

Critical choke points

• Extra Deck must be cut by 6 before the list is legal; the cut choice decides which engine survives
• Single-copy Herald of the Arc Light and Monster Reborn are the only ways to reach several lines
• Starter access is high, but the Link-2/Link-3 base is needed for most finisher lines

Recommended changes

Evidence & confidence

• Verified: Extra Deck 21 exceeds Master Duel maximum 15; status Illegal; Main Deck 40 cards; no Main Deck copy-limit violations; Exact-name Phantom Knights purity 4 of 61 copies (6.6%); Archetype core present 5 of 25 (20%) per usage statistics; Hypergeometric starter, core, searcher and hand-trap probabilities
• Inferred: Engine accessibility and brick rate from starter density and situational-spell count; Interaction density from card text (about nine negation texts); Ceiling read from Link/Xyz finisher text; Going-first and going-second estimates
• Provisional: Meta Power (no dated metagame sample); Matchup fit (no tournament link); Side adaptability (no side deck in Master Duel)
• 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, starter and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied Master Duel has no side deck, so D12 has no post-side evidence
