Rikka Deck #772380 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 51/100 (±8 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Toolbox, Stun
• Format: ocg

Legality

Main 56 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Plant-engine board built from Rikka starters (Glamour, Petal, Konkon, Mudan, Princess), converting into Xyz/Link boss monsters such as Queen of the Night, Teardrop, Frozen Lady Justice and Hyperyton.; Recursion through Rikka Tranquility and GY-revival effects (Hellebore, Kanzashi) to rebuild a Plant board after disruption.
• Turn 1 (going first): Open a Rikka starter (Glamour or Petal) and search a second Rikka piece, then Normal or Special Summon Plant monsters into an Xyz or Link extension. Hand traps stay in hand as backup.
• Turn 2 (going second): Use the six-card hand to hold up hand traps and negations (Ash Blossom, Infinite Impermanence, Effect Veiler, Droll and Lock Bird, Maxx C) and force the opponent to commit before deploying a boss.
• Recovery: Recover from a broken board via Rikka Tranquility, Rikka Petal from the GY and Kanzashi or Hellebore revival, plus Pot of Prosperity for card advantage.
• After siding: No side deck is registered, so there is no measurable post-side plan. Any adjustment is an untested assumption.

Why it scores here

The deck opens a Plant engine reliably on the strength of its Rikka starter density: P(at least one archetype-core card in a 5-card opener) is about 0.97, though a triple-copy starter such as Rikka Glamour hits in the opener only about 25% of the time (Inferred). Its interaction is the strongest part of the system, with 8 hand traps, 17 negation-text cards and several Solemn and Ash Blossom copies that let it stay in the game when going second. Conversion is capped by the absence of any recorded boards, so the ceiling and median can only be read from card text (Inferred). Only 24% of the main deck is exact Rikka and about 27 cards are generic tech or staples, which costs consistency and efficiency, and the deck has no side deck, which removes any post-side plan. The score comes from consistency, interaction and resilience on the system as a whole, not from Rikka being a popular archetype and not from averaging the individual card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 55, Going First ≈ 55, Going Second ≈ 52, Meta = provisional, Tournament Reliability ≈ 50. Modifiers: No side deck (-3). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.97 · 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

• Dense Rikka starter and searcher density gives reliable T1 engine access
• Eight hand traps and multiple negation routes give strong interaction when going second
• Extra Deck fully used with several high-ATK Xyz finishers and Link support

Weaknesses

• Only about 24% exact archetype purity; roughly 27 generic or staple slots dilute the engine
• No side deck, so there is no post-side plan
• No recorded boards, so combo conversion and median output can only be estimated from text

Critical choke points

• Rikka starter access depends on triple-copy Glamour or double-copy Petal, each unlikely to appear in the opener
• Going-first plan depends on Plant summons with no hand-trap backup

Recommended changes

Evidence & confidence

• Verified: Main 56, Extra 15, Side 0 all within OCG size rules; All restricted cards are at or below their legal copy limits; Archetype purity 23.9% and copy histogram match the composition data
• Observed: Usage statistics: 17 of 24 typical core cards present (70.8%)
• Inferred: P(>=1 archetype-core card in opener) ~0.97 from hypergeometric estimate; Interaction density high from negation and hand-trap text; Consistency and brick estimates from composition and card text
• Provisional: Meta and matchup fit cannot be scored without a dated meta sample
• Data gaps: no combos supplied; combo floor, median and ceiling are text-only inference no tournament link; archetype meta-share and per-pilot record absent no win-rate telemetry; going-first/second and matchup rates unknown Meta Power provisional unless a dated metagame sample is supplied no side deck; post-side performance cannot be measured
