Zefra Deck #454282 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 32/100 (±10 · Confidence: Low)

• Primary strategy: Toolbox
• Secondary strategies: Control
• Format: master-duel

Legality

Main 60 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 3 violation(s).

Identity & game plan

• Win condition: Summon high‑ATK Zefraath or Superheavy beatsticks and overwhelm with draw engines; Control the board with hand traps and negate opponent plays
• Turn 1 (going first): Open with hand traps (Ash Blossom, Ghost Ogre, Maxx C) to disrupt opponent, use searchers (Oracle of Zefra, Zefra Providence) to fetch Zefra monsters, set Pendulum scales and aim for a Zefraath or Superheavy Samurai beatstick by turn 3.
• Turn 2 (going second): With a six‑card hand, prioritize hand traps, then use draw engines (Mulcharmy Fuwalos, Purulia) to refill, set up Pendulum zones and launch a late‑turn Zefra or Superheavy summon to outpace the opponent.
• Recovery: If the engine is disrupted, rely on the abundant draw cards (Maxx C, Mulcharmy effects) and the many searchers to rebuild Pendulum zones and re‑summon a beatstick.
• After siding: No side deck present; the deck lacks a dedicated post‑side plan.

Why it scores here

The deck can reliably open with multiple hand traps and searchers, giving it a decent chance to start a Zefra or Superheavy beatstick. Its draw engines (Mulcharmy, Maxx C) provide reasonable resource recovery, and the abundance of negation cards adds resilience against disruption. However, the list is heavily off‑archetype, contains illegal cards, and lacks a clear combo line or side plan, which drags down overall consistency and pilotability. Popularity of the Zefra archetype does not boost the score because the deck does not follow the core engine. Consequently the structural power is modest and the final contextual score is capped low due to illegality.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 49, Going First ≈ 45, Going Second ≈ 40, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: Illegal status (-10); Over‑copy limit (-5). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.69 · key two-card combo ≈ — · full-brick estimate ≈ 0.31 (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, Ghost Ogre, Maxx C, Nibiru)
• Multiple draw engines (Mulcharmy Fuwalos, Purulia, Maxx C)
• High searcher count (≈94% chance of a searcher in opening hand)

Weaknesses

• Illegal cards and over‑copy violations
• Very low archetype purity (12%) leading to potential brick
• No side deck, no post‑side contingency
• No recorded combo lines; reliance on single beatsticks

Critical choke points

• Access to a Zefra core monster (Zefraath, Oracle of Zefra) in opening hand
• Availability of draw engines after disruption

Recommended changes

Evidence & confidence

• Verified: legality status and copy limits; card text excerpts for role hints; copy histogram and composition data
• Observed: hand‑trap count from composition; searcher group probability from probabilities
• Inferred: engine accessibility probability; brick estimate from archetype core group; resource economy from draw engine cards; interaction quality from trap cards
• Provisional: matchup format fit 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, game‑level, brick/starter/OTK rates) — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
