Archfiend Deck #457368 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 28/100 (±8 · Confidence: Medium)

• Primary strategy: Toolbox
• Secondary strategies: Midrange, Pendulum Spam
• Format: master-duel

Legality

Main 51 / Extra 13 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Pendulum Summon Igknight engine into attacker setup with equip synergy; Synchro/Link toolbox combo for grind and recovery
• Turn 1 (going first): Set up Pendulum Scale with Igknight pair, establish searcher engines (Painful Decision, Summoner's Art), float into Link monsters for field presence
• Turn 2 (going second): Use Igknight Pendulum effects to search and recover, leverage Synchro monsters (Power Tool Braver Dragon, Garden Rose Maiden) as removal/recursion tools
• Recovery: Recursion via World Legacy Succession, Garden Rose Maiden graveyard recovery, Synchro Tuner chain (Ib the World Chalice Justiciar) for World Legacy searches
• After siding: No side deck supplied; post-side adaptability cannot be verified

Why it scores here

This deck abandons the core Archfiend archetype (0% core presence) in favor of an Igknight Pendulum shell with scattered toolbox synergies. The Igknight engine provides consistent searcher access (P≥1 searcher in opening hand ≈ 99.7%), and Pendulum effects enable recovery and hand extension. However, the deck lacks a cohesive combo structure, board-closing power, or meaningful interaction. No scored combos are present in the evidence, and the endboard appears to rely on low-ATK Igknight bodies plus unreliable equip synergies. Interruption resilience is weak—the Synchro and Link toolkit are niche slots rather than core lines. The deck does not benefit from archetype meta-share, nor from the archetype's established strengths, making it a fundamentally misbuilt list that sacrifices focus for flexibility without achieving either.

Dimension scores

How the score was computed

Strategy profile: 0.6 Toolbox + 0.4 Midrange. Structural ≈ 44, Going First ≈ 48, Going Second ≈ 38, Meta = provisional, Tournament Reliability ≈ 41. Modifiers: Archetype Abandonment (-8); No Combo Evidence (-4); Weak Going-Second Plan (-3); One-Ofs Burden (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta Provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 1 · key two-card combo ≈ — · full-brick estimate ≈ 0.02 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Extremely high searcher density (99.7% probability of opening spell searcher) ensures hand consistency and float
• Pendulum Summon mechanic allows recovery and replay of Igknight bodies across turns
• Synchro toolbox (Power Tool Braver Dragon, Garden Rose Maiden, Ib) provides multi-layered recursion and removal
• Low brick rate; almost any opening hand contains a playable spell or Igknight starter
• Synchro Tuner chain (Ib → World Legacy Succession) enables grind and extended turn sequences

Weaknesses

• Runs 0% core Archfiend cards—archetype label is misleading; no synergy with Archfiend support
• Endboard is low-stat (Igknight 0–2400 ATK) and relies on fragile equip synergies for pressure
• Only one card with negation text (Rescue Ferret); interaction quality is poor for a Master Duel environment
• Toolbox slots (Bamboo Sword, scattered equips, Squeaknight, Sublimation Knight) are niche and inconsistent
• Going-second strategy is underdeveloped; lacks dedicated board-breaker or forced interaction
• 18 one-ofs dilute consistency and create decision overload without clear payoffs
• No hand traps; vulnerable to early disruption
• Synchro combos require tuner setup and specific level combinations; fragile to single negation

Critical choke points

• Pendulum Scale setup: both left and right zones must be filled; failure to establish scales locks the main engine
• Tuner access: Spore, Ruddy Rose Witch, Infernoble Knight - Renaud, and Squeaknight are the only tuners; loss of one tuner narrows Synchro lines
• No hand traps: opponent's T1 negation (e.g., Ash Blossom negating Painful Decision or Summoner's Art) can halt the turn entirely
• Equip synergy collapse: many equips (Axe of Despair, Bamboo Sword chain, Mage Power) are conditional on field state; board wipe ruins these lines
• Extra Deck bottleneck: many Extra Deck slots are 2-Link generics; deck relies heavily on Power Tool Braver Dragon and Ib for meaningful effects, both of which are choke points

Recommended changes

Evidence & confidence

• Verified: Deck is Legal in Master Duel (51 main, 13 extra, 0 side; no banlist violations); Legality check: Predaplant Verte Anaconda (Limited ×1), Reinforcement of the Army (Limited ×1), both properly limited; Archetype purity: 0/1 exact-name Archfiend cards run; 24 Igknight (37.3%), 22 generic (35.3%); Card text resolved for all 41 distinct main/extra cards; Searcher text identified: 34 cards tagged with searcher_text (Painful Decision, Summoner's Art, Igknight Pendulum effects, etc.)
• Observed: Igknight Pendulum effect is identical across all 8 Igknight cards: destroy Pendulum pair, search 1 FIRE Warrior from deck/GY; Extra Deck composition: 9 Link, 3 Synchro, 1 XYZ; no Fusions or Rituals; Copy histogram: 18 one-ofs, 11 three-ofs; 29 distinct main-deck cards; Synchro tuners present: Spore (1), Ruddy Rose Witch (1), Infernoble Knight - Renaud (1), Squeaknight (1); Ib (Synchro-Tuner, Extra)
• Inferred: P(≥1 searcher in hand 5) ≈ 0.997 from hypergeometric with 34 searcher-tagged cards; Brick rate estimated at ~2% due to high searcher saturation and Pendulum recovery; Combo ceiling inferred from Power Tool Braver Dragon (equips 3 from deck/GY) + Ib chain; estimated PowerIndex 52–65; Combo floor estimated at median index 48 from typical Pendulum-search-into-2-monster boards; Interruption resilience: single Ash on Painful Decision / Summoner's Art blocks turn; Tuner loss narrows Synchro paths; Going-second endurance: limited by absence of dedicated board-breaker or bounce; equip synergies are conditional; Archetype meta-share unknown in Master Duel; Archfiend core abandonment suggests non-viable positioning; Tournament reliability: high consistency (D1) but weak median output (D4), low going-second (D8), and post-side unknown create 41/100 reliability floor
• Provisional: Meta Power is null: no dated metagame sample supplied; Archfiend archetype meta-share in Master Duel is unknown; Archetype positioning vs current meta: assumed weak due to 0% core cards and no tournament link; Post-side adaptability: no side deck supplied; D12 marked 0; best-of-3 plan cannot be verified
• Data gaps: No combo data supplied: combo floor, median, and ceiling are text-based inferences only; no observed board frequency or resource signature No tournament link: archetype meta-share, per-pilot match record, and format positioning unknown No side deck: post-side plan and best-of-3 adaptability cannot be assessed; D12 Side Deck Adaptability set to 0 No win-rate telemetry: going-first/second sub-scores, matchup-specific resilience, brick rates, and OTK rates are not available in YGOVN Master Duel banlist and card availability: some synergies (e.g., Knightmare Phoenix in Extra) may not be legal in Master Duel; assumptions made based on legality check No guides evidence beyond one Vietnamese snippet: strategic intent and archetype pillars not clearly articulated in English-language sources
