Rikka Deck #750736 — Yu-Gi-Oh! Master Duel

Deck — Deck Power Evaluation

Final Contextual Deck Power: 49/100 (±6 · Confidence: Medium)

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

Legality

Main 60 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Plant link/Xyz board from a Rikka and Plant engine that lands 2200 to 2800 ATK boss monsters (Teardrop, Regulus, Hyperyton, Magnolia, Benghalancer) through the Rikka Princess, Mudan and Primula starter chain.; Aroma and Sunavalon link boards that add Plant pressure once the Extra Deck link pieces are live.
• Turn 1 (going first): Open with a 1-card starter (Rikka Princess, Rosalina or Loci), search a Rikka or Plant piece with Mudan, Petal or Glamour, then build a link or Xyz board through the Plant-only summon restriction.
• Turn 2 (going second): Use Ash Blossom and Droplet or Dark Ruler No More for interaction on the opponent's board, then rebuild through the Rikka searchers. The going-second line has no recorded data.
• Recovery: Recover through Rikka Petal and Rikka Queen Strenna recursion from the GY, plus Ragnaraika Bloom searches, after an interruption.
• After siding: No side deck is run (Side Deck size 0), so there is no post-side plan. Rely on in-game sequencing.

Why it scores here

The deck's Structural score comes from the system as a whole: the 18-copy Rikka core has about an 84% chance of at least one piece in a 5-card opening hand, and the 17 searchers give about an 82% chance of one. Starter diversity across Rikka, Ragnaraika and Rosalina lines helps interruption resilience. The recorded combo ceiling is low (best PowerIndex 38, median 32, no board or interaction data), so Combo Conversion and Floor score low even though the deck has strong 2200 to 2800 ATK Extra Deck bosses. Interaction (Ash Blossom x3, Droplet, Dark Ruler No More, Harpie's Feather Duster, Sunavalon Bloom) is credited as Inferred from card text. Popularity and archetype usage did not earn points, the 21% exact-name purity was not treated as a weakness on its own, and card scores were not averaged. The deck has no side plan and no meta data, so Final uses the no-meta formula and takes a modifier for engine conflict and the missing post-side plan.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 55.4, Going First ≈ 64, Going Second ≈ 54, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: engine conflict (-3); no_post_side_plan (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional, null). = 0.80*55.4 + 0.20*50 - 5 = 49.3

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.84 · key two-card combo ≈ — · full-brick estimate ≈ 0.16 (all Inferred)
• Combo output: best PowerIndex 38, median 32, board-per-starter 0
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Large core of Rikka searchers (17 searchers) with about 84% chance to hit the core in an opening 5
• Plant race density (43 of 60 main) keeps the summon restriction and Link Plant pieces coherent
• Strong Extra Deck bosses at 2200 to 2800 ATK plus redundant Links (Jasmine ×2, Dryas ×2)
• Interaction suite of 3 Ash Blossom, Droplet, Dark Ruler No More and Sunavalon Bloom

Weaknesses

• Only 21.3% exact-name Rikka purity; sub-archetype spread creates brick and engine-conflict risk
• Low recorded combo ceiling (best 38) and median (32) with zero board data
• No side deck, so no post-side plan
• Off-standard list: 11 of 25 archetype core cards present (44%); Maxx C, Droll & Lock Bird and Teardrop-style core support are missing or reduced

Critical choke points

• Rikka Princess and Plant-only summon restriction blocks non-Plant plays while face-up
• Single-card starters (Rikka Princess, Rosalina, Loci) carry the opening
• Extra Deck link pieces depend on Plant link material being present in hand or field

Recommended changes

Evidence & confidence

• Verified: Legal under master-duel size rules (60 main, 15 extra, 0 side); Limited cards Harpie's Feather Duster and One for One run at 1 copy, within the limit; Card stats and levels for the Extra Deck bosses
• Observed: 3 recorded combos with PowerIndex 29 to 38, median 32; Archetype usage stats: 11 of 25 core cards present (44%)
• Inferred: Opening-hand starter probability 0.84 and searcher probability 0.82; Interaction quality from card-text negation and removal hints; Going-first and going-second estimates
• Provisional: Meta power (no dated metagame sample); Side-deck adaptability (no side deck and no post-side data); Matchup and format fit (no tournament link)
• Data gaps: no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN (going-first/second, matchup, game-level, brick/starter/OTK rates) — those signals are Inferred or Unknown all 3 recorded combos have gameplay unknown and zero board/interaction summaries, so combo ceiling and floor are thin no side deck, so post-side adaptability is unmeasured Meta Power is Provisional unless a dated metagame sample is supplied
