Archfiend Deck #738751 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 54/100 (±5 · Confidence: Medium)

• Primary strategy: Control
• Secondary strategies: Midrange
• Format: master-duuel

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Attrition via trap interactions and Fiendish Rhino Warrior protection; Boss monster beatdown (Labrynth Archfiend, Archfiend's Advent, Dark Armed)
• Turn 1 (going first): Set multiple traps, establish Fiendish Rhino Warrior for monster protection, attack with Labrynth Archfiend/Advent while cycling resources
• Turn 2 (going second): Rely on face-down traps to disrupt opponent's plays, utilize attrition and card draw to stabilize, attack with protected fiends
• Recovery: Activate Dark Factory, Backup Team, Call of the Archfiend, and D.D. Post to recycle resources and maintain board presence
• After siding: None available; side deck is empty

Why it scores here

This Archfiend variant operates as a trap-heavy Control deck, relying on a dense suite of face-downs and Fiendish Rhino Warrior protection to stall and attrition opponents. While the core group reaches 22 copies yielding a 98.7% chance to draw something relevant, the extreme trap commitment (21/40) severely hampers opening-hand flexibility and combo conversion. The deck excels in end-board interaction and resource recovery through traps like Dark Factory and Backup Team, but its complete lack of hand traps cripples its going-second viability against established boards. With an empty side deck and no recorded combo lines, the system remains fragile to disruption and unable to adapt post-side, capping its overall reliability.

Dimension scores

How the score was computed

Strategy profile: Control. Structural ≈ 57, Going First ≈ 60, Going Second ≈ 30, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Empty Side Deck (-5); Zero Hand Traps (-4); Trap Overcommitment (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.99 · key two-card combo ≈ — · full-brick estimate ≈ 0.15 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• High trap interaction density provides versatile board control
• Strong card advantage and recovery suite via Dark Factory, Backup Team, and Call of the Archfiend
• Fiendish Rhino Warrior offers reliable protection for key fiend monsters

Weaknesses

• Zero hand traps cripples going-second play against established boards
• Empty side deck prevents post-match adaptation and meta tuning
• Extreme trap ratio causes opening-hand bricks and slows overall tempo

Critical choke points

• Lack of hand traps makes going-second highly dependent on opponent mistakes and favorable draws
• Face-down trap reliance is vulnerable to board-breaking effects and non-targeted destruction
• Disjointed extra deck lacks synergy with main deck engine, creating resource disconnect

Recommended changes

Evidence & confidence

• Verified: Legality confirmed: 40/15/0 split matches Master Duel rules.; Core archetype group comprises 22 copies with 98.7% opening probability.
• Inferred: Dimension scores derived from hypergeometric probabilities and card-text role analysis.; Strategy classified as Control due to 21-trap density and attrition-focused game plan.; Going-second power penalized for zero hand traps and reliance on face-downs.
• Provisional: Matchup format fit estimated without dated metagame telemetry.; Meta Power marked provisional due to absent tournament link.
• 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 exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
