Rikka Deck #673115 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

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

Legality

Main 54 / Extra 16 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Link and Xyz boss monsters (Teardrop the Rikka Queen, Rikka Queen Strenna, Underworld Goddess, Aromalilith Magnolia) converting a board that the Rikka and Aroma engines build; Rose and Sky Striker finishers and Synchro/Link pressure once the Plant-tribute loop is live
• Turn 1 (going first): Open a Plant starter (Rikka Petal, Mudan, Primula, Aromage Laurel) and extend through Rikka Glamour or Rikka Konkon into an Xyz or Link boss, keeping Ash Blossom and Maxx C up as interaction
• Turn 2 (going second): Use Ash Blossom, Evenly Matched, Infinite Impermanence, Nibiru, and Maxx C to break the opponent's first summon, then rebuild Rikka and Aroma through recursion (Rikka Petal, Rikka Queen Strenna GY effect)
• Recovery: Rikka Petal and Strenna recover a Plant or Rikka card from the Deck or GY; Aromaseraphy Angelica and Blessed Winds recur Plants from the GY and grant LP
• After siding: Not evaluable: the list has an empty Side Deck, so no post-side plan is present in the evidence

Why it scores here

The score comes from the deck as a system and not from averaging card scores: the Rikka and Aroma engines each have roughly 14 exact-name copies, and the 16-card archetype core has about an 84 percent chance of at least one copy in a 5-card opening hand (Inferred). Interaction is dense (13 hand traps, 14 removal-text cards, 8 negation-text cards), which supports resilience and going-second pressure. Conversion is capped by the absence of recorded boards, so the ceiling (Teardrop, Strenna, Underworld Goddess) and the median are both text-only estimates. The list cannot be scored normally because it is Illegal: two Forbidden cards are in the Main Deck and the Extra Deck is one card over the limit, so the score is a theoretical cap, not a playable rating. Popularity and archetype usage are not counted as power; the list covers only 42 percent of the archetype's core usage.

Dimension scores

How the score was computed

Strategy profile: 0.8 Midrange + 0.2 Toolbox (structural only; not used for the final score). Structural ≈ 52, Going First ≈ 50, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Banlist exposure (-8); Engine conflicts (-4). Final formula: Illegal: theoretical cap. Normal formula 0.80*Structural(52) + 0.20*TournamentReliability(40) + Modifiers(-12) = 37.6, capped to 30 because the list is Illegal (Meta provisional, null)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.84 · 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 interaction: 13 hand traps, 14 removal-text and 8 negation-text cards
• High-impact Link and Xyz bosses (2400-3000 ATK) with recursion for resilience
• Engine core is well covered in hand (about 84 percent of openers)

Weaknesses

• Illegal list: Forbidden Called by the Grave and Naturia Rosewhip in the Main Deck
• Extra Deck is one over the OCG limit (16 of 15)
• Two engines (Rikka and Aroma) with weak coherence (20 percent exact-name purity)
• Empty Side Deck, so no post-side plan

Critical choke points

• The Forbidden cards cannot be legally played in OCG, so the list is not playable as submitted
• Going-first lines depend on a single Plant starter in hand and a free Main Phase for the Rikka and Aroma chains

Recommended changes

Evidence & confidence

• Verified: Legality status Illegal: 2 Forbidden cards in the Main Deck and Extra Deck at 16 of 15; Main Deck 54 cards (33 distinct), Extra Deck 16 (13 distinct), Side Deck 0; Exact-name archetype purity 20 percent (14 of 70 copies); Banlist statuses for Ash Blossom (Semi-Limited), Maxx C (Limited), One for One (Limited), Crossout Designator (Limited), Hornet Drones (Limited)
• Inferred: P(at least one archetype-core card in a 5-card opener) about 0.84; Hand-trap density and interaction coverage (13 hand traps, 14 removal-text, 8 negation-text); Engine conflict between Rikka and Aroma conditions; Going-first and going-second estimates
• Provisional: Meta Power is null: no dated metagame sample and no tournament link; Matchup fit (D13) is set to a neutral 50 without a dated meta sample
• Data gaps: No combos supplied (total combos 0): combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record absent No win-rate telemetry for going-first/second, matchups, or brick/starter rates Side Deck is empty: no post-side evidence Deck title is null, so the list is identified only by archetype and id
