Legality

Main 60 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

  • Win condition: Establish board control with high‑ATK Zefra and Mythical Beast monsters while disrupting opponent with hand traps; Leverage hand‑trap suite and search effects to grind resources and out‑maneuver opponent
  • Turn 1 (going first): Open with Zefraath or Oracle of Zefra to add core Zefra cards, set hand traps (Ash Blossom, Maxx C, Droll) and begin searching for high‑ATK monsters
  • Turn 2 (going second): Use hand‑trap suite to lock opponent’s draws, then summon powerful monsters (Zefraath, Mythical Beast Master Cerberus, Superheavy Samurai) to pressure board
  • Recovery: Draw engines (Maxx C, Droll) and Zefra Providence’s graveyard protection to refill hand and protect key monsters
  • After siding: No side deck; relies on main‑deck flexibility

Why it scores here

The deck reliably opens with Zefraath or Oracle of Zefra, giving a decent chance (≈72%) to start its engine and a strong hand‑trap suite to disrupt the opponent. Searchers and draw effects provide good resource recovery, while high‑ATK monsters give offensive pressure. However, the list contains many off‑archetype cards, illegal copy limits, and no side deck, which reduces consistency, efficiency, and adaptability, capping the overall power despite solid control tools.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 70 P(at least one core starter in opening 5) ≈ 0.72 (Inferred)
D2 Opening-Hand Quality & Brick Management 55 12 three‑copy cards raise brick risk; hand‑trap density moderate (Inferred)
D3 Combo Conversion & Ceiling 60 No recorded combo boards; ceiling limited by lack of clear engine (Inferred)
D4 Combo Floor & Median Output 45 Median output inferred low due to missing combo data (Inferred)
D5 Interruption Resilience & Route Redundancy 65 10 hand‑traps and multiple negation cards give redundancy (Inferred)
D6 Resource Economy, Recovery & Grind 70 Search‑and‑draw cards (Maxx C, Droll, Zefra Providence) boost economy (Inferred)
D7 End-Board & Interaction Quality 65 Interaction density from Zefra Divine Strike, Nine Pillars, etc. (Inferred)
D8 Going-Second & Board-Breaking Power 55 Hand‑trap group P(at least one in 6) ≈ 0.68 supports going‑second pressure (Inferred)
D9 Offensive Pressure & Closing Power 60 High‑ATK monsters (Zefraath 3450, Cerberus 2800) provide closing power (Inferred)
D10 Main Deck Efficiency & Flexibility 40 Archetype purity only 13.3% and many off‑archetype cards lower efficiency (Inferred)
D11 Extra Deck Efficiency & Coverage 45 Extra deck filled with unrelated links/xyz; includes forbidden cards (Inferred)
D12 Side Deck Adaptability 30 Side deck empty; no post‑side plan (Inferred)
D13 Matchup Coverage & Format Fit 30 No tournament context or meta data supplied (Provisional)
D14 Pilotability & Error Tolerance 40 Complex pendulum and hand‑trap interactions increase error tolerance (Inferred)

How the score was computed

Strategy profile: Control. Structural ≈ 56, Going First ≈ 58, Going Second ≈ 54, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Illegal card violations (-10). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional)

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.72 · key two-card combo ≈ — · full-brick estimate ≈ 0.28 (all Inferred)
  • Combo output: best PowerIndex —, median —, board-per-starter —
  • Turn order: 0 going-first lines vs 0 going-second lines

Strengths

  • Strong hand‑trap suite (Ash Blossom, Maxx C, Droll, etc.)
  • Multiple search and draw effects for resource recovery
  • High‑ATK monsters provide solid closing power

Weaknesses

  • Illegal card copies (Maxx C, Droll, Apollousa, Bagooska) and forbidden cards
  • Low archetype purity; many off‑archetype splashes increase brick risk
  • No side deck limits adaptability
  • Lack of clear combo line reduces median output

Critical choke points

  • Reliance on Zefraath or Oracle of Zefra to start engine
  • Need to avoid drawing illegal copies that force deck to be illegal in play
Priority Remove Add Reason
1 Apollousa, Bow of the Goddess Zefra core monster (e.g., Zefraath extra copy) Forbidden card; replace with legal core to improve legality and consistency
2 Number 41: Bagooska the Terribly Tired Tapir Additional Zefra or Superheavy Samurai link monster Forbidden extra‑deck slot; replace with legal link for extra‑deck efficiency
3 Extra copies of Maxx C (reduce to 1) and Droll (reduce to 2) More Zefra or Superheavy Samurai core cards Over‑copy limits cause illegality; aligning to copy limits improves playability

Evidence & confidence

  • Verified: Card text excerpts; Legality status and copy limits; Hypergeometric probabilities
  • Inferred: Engine accessibility from core starter probability; Brick risk from copy histogram; Combo ceiling/floor from lack of combo data; Resource economy from searcher and draw card counts; Interaction quality from trap and negation counts; Extra‑deck efficiency from breakdown and forbidden cards; Pilotability from hand‑trap and pendulum complexity
  • Provisional: Matchup coverage due to missing tournament data
  • 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, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
