Deck — Deck Power Evaluation
Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)
| Overall score | Value |
|---|---|
| Structural Deck Power | 52 |
| Going First | 50 |
| Going Second | 48 |
| Meta Power | provisional |
| Tournament Reliability | 45 |
- Primary strategy: Combo
- Secondary strategies: Toolbox, Midrange
- Format: master-duel
Legality
Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).
Identity & game plan
- Win condition: Ritual and Link-based Nephthys boards led by Cerulean Sacred Phoenix (3000 ATK) and Nephthys, the Sacred Flame (2400 ATK), with Sacred Phoenix as a recursive follow-up; Greed/Pot of Extravagance card advantage and Herald negation shell (over the copy limit, so not reliable)
- Turn 1 (going first): Search with Pre-Preparation of Rites or Preparation of Rites, then use Rebirth of Nephthys to Ritual Summon a Nephthys monster into a Link or Ritual follow-up
- Turn 2 (going second): Use Raigeki, Lightning Storm, or Gryphon's Feather Duster to clear the board, then rebuild through Nephthys searchers and recursion (Chronicler, Disciple, Matriarch)
- Recovery: Chronicler of Nephthys, Disciple of Nephthys, and Sacred Phoenix's GY revival recycle Nephthys pieces; Awakening of Nephthys adds a second recovery path
- After siding: Not evaluable: the deck has no Side Deck, so there is no post-side plan
Why it scores here
The list is Illegal: Pot of Extravagance (2 copies vs 1) and Herald of the Arc Light (3 vs 1) break the Master Duel Limited caps, so the score is capped and the evaluation is structural-only. Within that cap, the Nephthys engine has a real redundant core: 11 searcher-text cards (P(at least one searcher in hand of 5) ≈ 0.82, Inferred) and three Rebirth of Nephthys, so the deck usually reaches a first Ritual/Link line. Conversion is not verified because there are no recorded boards, so the ceiling (Cerulean Sacred Phoenix, Nephthys, the Sacred Flame) and the median are text-based reads only. Interaction is moderate and entirely spell-based (Raigeki, Lightning Storm, Gryphon's Feather Duster, Monster Reborn; no hand traps), and the score assumes no hand-trap defence. The score comes from consistency and recursion on the system, not from Greed's popularity, and not from averaging card scores.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 62 | P(≥1 of a 3-copy starter in hand of 5) ≈ 0.34; searcher group P(≥1) ≈ 0.82; 2-card Rebirth bootstrap (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 55 | 11 searchers and 3 Rebirth reduce dead hands, but ritual-heavy hands can conflict on Normal Summons and Ritual material (Inferred) |
| D3 | Combo Conversion & Ceiling | 55 | Ceiling from Cerulean Sacred Phoenix and Nephthys, the Sacred Flame; no recorded boards, so semantic read only (Inferred) |
| D4 | Combo Floor & Median Output | 45 | Median is unknown because combos_evidence has zero parseable boards; scored conservatively (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 55 | Recursion via Chronicler, Disciple, Devotee, and Sacred Phoenix GY revival gives independent follow-ups (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 55 | Multiple recovery engines and searchers recycle GY Nephthys cards; net advantage unmeasured (Inferred) |
| D7 | End-Board & Interaction Quality | 60 | Removal-text count 31 and negation text from Herald and Matriarch, but no hand traps and the Herald negation is over the copy limit (Inferred, text-based) |
| D8 | Going-Second & Board-Breaking Power | 50 | Raigeki, Lightning Storm, and Feather Duster give some board breaking; no going-second split available (Inferred) |
| D9 | Offensive Pressure & Closing Power | 55 | 3000 ATK Phoenix and 2400 ATK Link Flame provide closing power; no end-board telemetry (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 55 | 40-card Main with 20 distinct cards and 3-copy engine density; compact but with off-archetype and staple load (Inferred) |
| D11 | Extra Deck Efficiency & Coverage | 60 | 15 Extra slots filled by Link and Synchro with the Nephthys/Herald core; Herald of the Arc Light is over the copy limit (Verified/Inferred) |
| D12 | Side Deck Adaptability | 15 | No Side Deck at all, so no post-side adaptability (Verified) |
| D13 | Matchup Coverage & Format Fit | 40 | No tournament link, no meta-share, no dated sample; Provisional only |
| D14 | Pilotability & Error Tolerance | 45 | Multi-step Ritual and Link sequencing with several decision points and bricking risk (Inferred) |
How the score was computed
Strategy profile: Combo primary, Toolbox secondary (structural only). Structural ≈ 52, Going First ≈ 50, Going Second ≈ 48, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-8); no side deck (-4). Final formula: No reliable metagame: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 0.80*52 + 0.20*45 - 12 ≈ 38.6, then capped to 30 because the list is Illegal (theoretical/structural-only)
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.34 · 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
- Dense Nephthys searcher and recursion network (11 searchers, multiple GY recovery cards)
- Strong Ritual and Link ceiling with Cerulean Sacred Phoenix and Nephthys, the Sacred Flame
- Several spell-based answers (Raigeki, Lightning Storm, Feather Duster, Monster Reborn)
Weaknesses
- Illegal list: Herald of the Arc Light and Pot of Extravagance over the copy limit
- No Side Deck, so no post-side adaptability
- No hand traps or floodgates, so no interaction on the opponent's turn
- Consistency rests on a single ritual bootstrap (Rebirth of Nephthys, 3 copies)
Critical choke points
- Rebirth of Nephthys (3 copies) as the main Ritual engine
- Nephthys Ritual material as the Link and Ritual follow-up route
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | 1 copy of Pot of Extravagance (2 → 1) | 1 legal non-Limited card or a 1-copy alternative | Restores legality; the deck cannot receive a normal score while over the limit |
| 2 | 2 copies of Herald of the Arc Light (3 → 1) | A Nephthys-compatible Extra Deck card | Herald is Limited and over the copy limit; removing the excess copies is required for legality |
| 3 | Off-archetype staples (Salamangreat, generic cards) | A Side Deck of 5–15 cards | Side Deck is empty; a Side Deck would give a post-side plan and resilience for best-of-3 |
Evidence & confidence
- Verified: Legality: Illegal (Pot of Extravagance 2/1, Herald of the Arc Light 3/1); Main 40 and Extra 15 are within Master Duel size rules; Side Deck is 0 cards; No tournament link and no recorded combo boards
- Observed: Usage stats: Greed core cards present at 80% of archetype core (20/25)
- Inferred: Starter and searcher hypergeometric estimates; Recursion and interaction reads from card text; Dimension scores D1–D14
- Provisional: Meta Power and D13 matchup/format fit (no dated metagame sample)
- 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 — those signals are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied
