Naturia Deck #736741 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 33/100 (±8 · Confidence: Low)

• Primary strategy: Toolbox
• Secondary strategies: Control, Stun
• 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: Unverified: no combos supplied. Structurally, the Extra Deck offers Synchro/Fusion/Xyz boss options (Chengying 3000 ATK, Ecclesia 2500 ATK, TY-PHON 2900 ATK, Dugares) that a Naturia or Runick board can reach, but no line is recorded.; Runick Quick-Play spells that skip the next Battle Phase and banish cards, followed by Extra Deck Runick summons (Geri, Hugin, Sleipnir).
• Turn 1 (going first): Open on a Naturia starter (Sacred Tree, Camellia, Mole Cricket or Blessing) and hold Ash Blossom, Droll and Maxx C as interaction. Use Runick spells to remove an opposing Special Summon and send a Runick monster from the Extra Deck.
• Turn 2 (going second): Respond with hand traps (Ash, Droll, Maxx C) and Quick-Play removal (Runick Slumber, Destruction, Smiting Storm, Freezing Curses) to break the opponent's board before rebuilding through Naturia Sunflower and Mole Cricket.
• Recovery: Runick Fountain recycles up to 3 Runick Quick-Play spells from the GY, and Runick Tip and Naturia Blessing re-search. Recovery depends on the GY containing enough Runick spells.
• After siding: Not applicable: the deck has no side deck (Side Deck size 0) and Master Duel offers no post-side plan.

Why it scores here

This list is Illegal (two cards over their copy limits), so it is scored as a theoretical, structural-only read and the final figure is a capped reference, not a normal contextual score. Its strongest signal is interaction: six hand traps, Ash Blossom, Droll and Maxx C, plus a layer of Quick-Play removal and negation, which lifts the end-board interaction dimension. The engine is less certain: the core Naturia group is almost always opened (Inferred), but the power cards are spread across three-copy starters with only 13 monsters in the Main Deck, so bricks and reactive hands are likely. Conversion and floor are unscored because no combos were supplied, and the Extra Deck mixes Naturia, Runick, Branded, Ecclesia, Fleur, Swordsoul and generic monsters, which weakens engine coherence. Archetype popularity and usage data did not earn points, and no card scores were averaged into the deck.

Dimension scores

How the score was computed

Strategy profile: Toolbox. Structural ≈ 46, Going First ≈ 45, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist/copy-limit exposure (-6); no combo evidence and mixed Extra Deck (-4); thin monster count / reactive hands (-2). Final formula: Illegal list: theoretical/structural-only. 0.80*46 + 0.20*40 = 44.8, then modifiers total -12 = 32.8, rounded to 33 (capped reference, not a normal Final score).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.99 · key two-card combo ≈ — · full-brick estimate ≈ 0.01 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Six hand traps and multiple Quick-Play negations and removal give broad interaction
• Core Naturia group is almost always opened (about 99%, Inferred)
• Runick Fountain and Runick Tip provide recursion and recovery
• Extra Deck has high-ATK bosses (Chengying 3000, TY-PHON 2900, Ecclesia 2500)

Weaknesses

• Illegal as built: The Fallen & The Virtuous and Radiant Typhoon Vision are over their copy limits
• Only 13 Main Deck monsters against 27 spells/traps, so monster-less hands are likely
• Extra Deck mixes archetypes without a clear engine: Albion needs Fallen of Albaz, which is not in the evidence
• No side deck and no recorded boards, so the power ceiling and post-side plan are unmeasured

Critical choke points

• Naturia monster access: few monsters in the Main Deck, so the engine depends on drawing one of 13
• Runick spells require a Battle Phase skip and an Extra Deck Runick summon, which limits the number of uses per turn

Recommended changes

Evidence & confidence

• Verified: Illegal status: The Fallen & The Virtuous 3 run vs 2 legal; Radiant Typhoon Vision 2 run vs 1 legal (Verified); 40 Main / 15 Extra / 0 Side; sizes within Master Duel rules (Verified); Card text and banlist for all listed cards (Verified); Naturia Sunflower legal to 3 copies (Verified)
• Inferred: Opening-hand estimates and brick rates from the hypergeometric table (Inferred); Interaction density and negation layers from card text (Inferred); Toolbox strategy classification from the composition (Inferred); Runick Extra summon and Battle Phase cost from card text (Inferred)
• Provisional: Meta Power is null: no dated metagame sample (Provisional); D13 matchup fit scored provisional (Provisional)
• Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and match record absent No win-rate telemetry: going-first/second, matchup, brick and OTK rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied usage statistics in this deck flags conflict with the cards list (e.g. Super Starslayer TY-PHON, Baronne de Fleur, Chengying, Coral Dragon, Naturia Beast, Sleipnir, Geri, Hugin and Dugares are in the cards list but flagged false), so the core-match figure is unreliable Fallen of Albaz (Albion's required material) is not in the evidence list No side deck data: Master Duel side deck is absent
