Naturia Deck #773823 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 52/100 (±8 · Confidence: Medium)

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

Legality

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

Identity & game plan

• Win condition: Runick Quick-Play spells Special Summon a Runick Fusion (Geri, Hugin, Sleipnir) from the Extra Deck to the Extra Monster Zone while removing or negating opposing cards; Camellia-enabled Synchro/Xyz (Naturia Beast, Baronne de Fleur, Chengying) supplies the board (Inferred, text-only); Synchro and Rank-4 Xyz lines built from Naturia Camellia (sole Tuner and sole Level 4 main-deck monster)
• Turn 1 (going first): Open a Runick Quick-Play spell (17 copies) to remove or negate the first threat and summon a Runick Fusion to the EMZ; hold Naturia Camellia or Naturia Mole Cricket for a Synchro or Xyz follow-up
• Turn 2 (going second): Droll and Lock Bird or Maxx C as hand traps (P of at least one in a 6-card hand is about 0.39), then a Runick Quick-Play removal spell on the opponent's turn
• Recovery: Runick Fountain returns up to 3 Runick Quick-Play spells from the GY to the bottom of the Deck and draws that many; Naturia Sacred Tree searches a Naturia card when sent to the GY; Geri and Hugin add a non-Quick-Play Runick spell from the GY
• After siding: None. Side count is 0 (legal range 0 to 15), so the list carries no post-side plan

Why it scores here

The deck's reliable function is interaction: 17 Runick Quick-Play spells give roughly a 95 percent chance of at least one in a 5-card opening hand, and each one removes, negates or banishes while also summoning a Runick Fusion from the Extra Deck. Consistency is decent but not clean, because only 10 of 40 main-deck cards are monsters, so about 22 percent of opening hands contain no monster. Conversion relies on Naturia Camellia as the only Tuner and the only main-deck Level 4 monster, which gates most Synchro and Rank-4 Xyz lines; no recorded boards exist, so the ceiling and median are text-based inference. Resilience and recovery are the strongest parts of the system, through Runick Fountain recursion, Naturia Sacred Tree search and several independent interaction routes. Closing power is held down by the Battle Phase skip that every Runick spell imposes, and the list has no side deck. The score comes from consistency, interaction and recovery on the system as a whole. It is not a reward for Naturia's popularity, and no card scores were averaged.

Dimension scores

How the score was computed

Strategy profile: Control. Structural ≈ 58, Going First ≈ 60, Going Second ≈ 49, Meta = provisional, Tournament Reliability ≈ 56. Modifiers: Split identity and engine conflict (-4); Single Tuner and Level 4 choke point (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers; Meta provisional; D13 excluded and weights renormalized over 93 (Structural = sum/93)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.95 · 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

• 17 Runick Quick-Play spells, each with a removal or negation mode and an Extra-Deck Runick summon, give high start-up reliability
• Layered interaction: removal and destruction spells, Forbidden Droplet negation, Naturia Sunflower and Naturia Beast negation, Baronne de Fleur, Droll and Lock Bird and Maxx C hand traps
• Recursion through Runick Fountain and Naturia Sacred Tree search; three copies of most engine spells
• No floodgate reliance, and Extra Deck covers Fusion, Synchro, Xyz and Link

Weaknesses

• Monster-light: 10 monsters in 40 cards, so about 22 percent of opening hands contain no monster
• Every Runick Quick-Play spell skips the next Battle Phase, which caps closing pressure
• Split identity: Runick dominates the main deck and exact-name Naturia purity is 25.5 percent
• No Runick monsters in the Main Deck, so Geri, Hugin and Sleipnir need a Runick spell to reach the field and cannot be Fusion Summoned from the Main Deck
• No side deck, so there is no post-side adjustment
• No recorded combo boards, no tournament data and no win-rate telemetry

Critical choke points

• Naturia Camellia: the sole Tuner and the sole main-deck Level 4 monster (3 copies, P(at least one in 5 cards) = 0.34); it gates Synchro and Rank-4 Xyz lines
• Runick Quick-Play spell density (17 copies) as the only route to Runick Extra Deck summons; redundant but single-category
• Single-copy Limited cards (Runick Destruction, Runick Fountain, Maxx C) are not key engine pieces and do not create banlist exposure

Recommended changes

Evidence & confidence

• Verified: Main Deck 40, Extra Deck 15, Side Deck 0; legal under Master Duel size rules (40 to 60 / 0 to 15 / 0 to 15); All restricted cards are within legal copy limits (Limited 1, Semi-Limited 2); Main Deck composition: 27 spells, 10 monsters, 3 traps; 19 distinct; exact-name Naturia purity 25.5 percent; Extra Deck: 5 Fusion, 5 Synchro, 3 Xyz, 2 Link (13 distinct)
• Inferred: P(at least one Runick Quick-Play spell in 5 cards) ≈ 0.95; P(no monster in 5 cards) ≈ 0.22; P(at least one Camellia in 5 cards) = 0.34; Camellia is the sole Tuner and Level 4 enabler; Runick spells provide repeated removal, negation and Extra-Deck summons; interaction density is semantic; Battle Phase skip cap on closing pressure
• Provisional: Meta Power (null) and matchup fit (D13) need a dated metagame sample; Post-side performance (D12) has no evidence
• Data gaps: no combos supplied; combo floor, median and ceiling are text-only inference no tournament link; archetype meta-share and per-pilot record are absent usage statistics in this deck flags show false for Extra Deck cards (Super Starslayer, Evilswarm, Number 60, Chengying, Baronne, Tri-Edge, Coral Dragon, Naturia Beast, Sleipnir, Geri, Hugin) even though cards[] lists them in zone extra; core_present 14 of 25 is therefore an undercount and was not used no win-rate telemetry (going-first, going-second, matchup, brick or starter rates) Meta Power is Provisional without a dated metagame sample side deck empty, so post-side performance is unknown
