Greed Deck #773784 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 35/100 (±10 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Midrange, Toolbox
• 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: Nephthys Link and Ritual boards (Cerulean Sacred Phoenix, Sacred Phoenix, Nephthys, the Sacred Flame) converting Ritual Summons into big attackers and removal; Raigeki and Lightning Storm as board-wipe reset when the Nephthys engine stalls
• Turn 1 (going first): Pre-Preparation of Rites or Preparation of Rites for a Ritual Monster, Rebirth of Nephthys to Ritual Summon into a Link line, then recursion through GY effects of Nephthys monsters
• Turn 2 (going second): Hand-based Nephthys monsters and Hand of Nephthys to summon Sacred Phoenix, with Raigeki or Lightning Storm as the answer to an established board; relies on the same ritual pathway as going first
• Recovery: Disciple, Chronicler, Defender and Matriarch of Nephthys recycle GY Nephthys monsters; Awakening of Nephthys and Last Hope of Nephthys provide targeted removal
• After siding: Not assessable: the deck has no Side Deck, so no post-side plan exists in the evidence

Why it scores here

The deck is scored as a system, not as an average of its cards. Its engine is a Nephthys Ritual/Link loop: Rebirth of Nephthys, Preparation pairs and several Nephthys searchers and recursion monsters feed Link and Ritual boards, which gives it redundant routes through the Main Deck. Consistency is moderate: P(at least one Rebirth of Nephthys in a 5-card opening) is about 0.34 and the searcher group reaches about 0.82, so starting the engine depends on search text rather than on any single card (Inferred). Interaction is real but thin: removal text appears on 31 cards and Raigeki and Lightning Storm provide board-wipe reset, while no hand traps are present. The deck is penalised for being Illegal: Pot of Extravagance and Herald of the Arc Light are run over their Limited copy limits, and the deck has no Side Deck, so the score is capped at a theoretical value of 35. Popularity or meta-share earned no points, and no win-rate or tournament evidence exists.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 56, Going First ≈ 55, Going Second ≈ 45, Meta = provisional, Tournament Reliability ≈ 48. Modifiers: banlist exposure (-10); no side deck (-2). Final formula: Illegal cap: uncapped 0.80*56 + 0.20*48 - 12 (modifiers) = 42.4, capped to 35 for an Illegal list (theoretical/structural only); Meta Power provisional

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

• Nephthys engine has several searchers and GY recursion effects that keep resources flowing
• Multiple boss Link and Ritual monsters at 2400 to 3000 ATK
• Two board-wipe spells (Raigeki, Lightning Storm) and targeted removal provide answers

Weaknesses

• Illegal copy counts on two cards: Pot of Extravagance x2 and Herald of the Arc Light x3 against a limit of 1
• No Side Deck, so no post-side adaptation
• Starter access is low: Rebirth of Nephthys is only about 0.34 in a 5-card opening
• No hand traps or floodgates to interact with the opponent's first turn

Critical choke points

• Rebirth of Nephthys (3 copies) is the main Ritual Summon route; without it the Ritual Monsters stall
• Herald of the Arc Light and Pot of Extravagance are over the Limited limit and must be reduced before the list is playable

Recommended changes

Evidence & confidence

• Verified: Main Deck 40 cards and Extra Deck 15 cards, both within the Master Duel size rules; Pot of Extravagance runs 2 copies against a Limited legal limit of 1; Herald of the Arc Light runs 3 copies against a Limited legal limit of 1; Side Deck count is 0; Archetype core: Nephthys is 32 of the 40 main-deck copies
• Inferred: P(at least one Rebirth of Nephthys in a 5-card opening) is about 0.34 (hypergeometric); Searcher-text group P(at least one in 5) is about 0.82; Interaction density from removal and negation text on the deck's cards
• Provisional: Meta Power and matchup fit are not supplied; no dated meta sample and no tournament link
• Data gaps: No combos supplied, so combo floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and per-pilot match record are absent No Side Deck supplied, so post-side plan cannot be evaluated No win-rate telemetry exists for going-first, going-second, matchup or brick rates Meta Power is provisional without a dated metagame sample
