Ancient Fairy Dragon Deck #774212 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 55/100 (±8 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Combo
• Format: master-duel

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Board flood through Yummy Synchro and Link summons, closing with Ancient Fairy Life Dragon and Cooky Yummy Way (Inferred from card text; no recorded boards to confirm); Ancient Fairy Dragon and Ancient Fairy Life Dragon card advantage and pressure once an Ancient Fairy Dragon Synchro is on the field (Inferred)
• Turn 1 (going first): Search or Special Summon through Regulus the Fairy Beast, Kuribon, Spore, or Yummy monsters toward a Synchro or Link-1 gate, with World of Spirits as the searcher; Ash Blossom and Forbidden Droplet stay up as interaction (Inferred)
• Turn 2 (going second): Hold Ash Blossom and Forbidden Droplet against the opponent's first summon or activation, then rebuild a Yummy board from the hand and graveyard (Inferred)
• Recovery: Yummy Surprise and Lollipo Way recover Yummy monsters from the graveyard; Mulcharmy draws and Piri Reis Map provide refuel (Inferred)
• After siding: No side deck in the export (0 cards); no post-side plan to evaluate (Provisional)

Why it scores here

The deck reliably finds a searcher (P(at least one of the 13 searcher-text copies in a 5-card opening hand) ≈ 0.88) and has a 3-copy Ash Blossom and 3-copy Forbidden Droplet for interaction, which carries most of the structural score (Inferred). The Yummy sub-engine is the real core, with 19 Yummy-tagged copies, several Level-2 Synchro Way monsters, and two Link-1 enablers that let Yummy monsters Special Summon from hand, so the Synchro and Link extra deck is coherent with the main deck. Its weakness is that the bootstrap runs through a Link-1 or Level-2 Synchro gate that is hard to reach on turn 1, and the Ancient Fairy Dragon label is misleading because only 10 of 55 main and extra cards carry the exact archetype name (18.2%). No combo boards were supplied, so the floor, median, and ceiling are text-only estimates and scored with low trust. Popularity and archetype usage did not earn points, and card scores were not averaged into the deck score.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 59.1, Going First ≈ 62, Going Second ≈ 54, Meta = provisional, Tournament Reliability ≈ 54. Modifiers: engine conflicts (-3); Limited card dependence (-1); Link-1 gate choke point (-1); coherent Yummy sub-engine (2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional) = 0.80*59.1 + 0.20*54 - 3 = 55

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.88 · 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

• Searcher density: 13 searcher-text copies give ≈0.88 chance of at least one in a 5-card opening hand
• Interaction: 3-copy Ash Blossom and 3-copy Forbidden Droplet, plus Eternal Sunshine and Herald of the Arc Light
• Coherent Yummy sub-engine with 19 copies and matching Level-2 Synchro and Link-1 enablers
• Legal and compact: 40 main cards, 15 extra, copy limits respected

Weaknesses

• Ancient Fairy Dragon label is misleading: only 18.2% exact-name purity, with Yummy as the dominant sub-archetype
• Fusion slot Thunder Dragon Colossus is off-engine with Thunder-only materials
• No side deck, so there is no post-side adaptation
• Bootstrap depends on a Link-1 or Level-2 Synchro gate that is not reachable on turn 1 from the hand

Critical choke points

• Link-1 or Level-2 Synchro on field gates Yummy hand Special Summons; the Link-1 enablers are single copies
• Ash Blossom and Forbidden Droplet are the only negation for the first summon
• Cupsy Yummy is Limited at 1 legal copy and cannot be replaced by a second copy

Recommended changes

Evidence & confidence

• Verified: Legal list: 40 Main, 15 Extra, 0 Side within master-duel size rules (Main 40-60, Extra 0-15, Side 0-15); Limited and Semi-Limited copies within limits: Cupsy Yummy 1 of 1 (Limited), Herald of the Arc Light 1 of 1 (Limited), Marshmao Yummy 2 of 2 (Semi-Limited); Copy histogram 12 x1, 5 x2, 6 x3 = 40 Main; Extra composition 10 Synchro, 4 Link, 1 Fusion; Exact-name archetype purity 18.2% (10 of 55 Main and Extra cards)
• Inferred: Consistency: ≈0.88 chance of at least one searcher-text card in a 5-card opening hand; Yummy Special Summon route depends on a Link-1 or Level-2 Synchro gate; Interaction density is high from card text (negation and removal text counts); Going-second hand-trap chance ≈0.39 for a 6-card hand; Dimension scores D1 through D14 as listed; Primary strategy Midrange with a secondary Combo read
• Provisional: Meta Power is null: no dated metagame sample supplied; D13 matchup and format fit scored neutral at 50 with no tournament or meta data; D12 side deck scored at 40 with no post-side data
• Data gaps: No combos supplied: floor, median, and ceiling are text-only inference (combo data total combos 0) No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry: going-first and going-second splits, matchup results, and brick or starter rates are Inferred Meta Power is Provisional: no dated metagame sample Side deck is empty (0 cards), so post-side performance cannot be assessed usage statistics in this deck flags are false for Extra-Deck cards that the deck does run (for example Ancient Fairy Dragon, Cooky Way, Linkuriboh), so core-card presence (48%) undercounts the list Deck title is null; archetype label Ancient Fairy Dragon describes only 18.2% of Main and Extra cards
