Rikka Deck #775058 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Low)

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

Legality

Main 48 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Plant Xyz boss line (Number 87: Queen of the Night 3200 ATK, Kanzashi, Rikka Queen Strenna, Sacred Tree Beast Hyperyton) reached through the Rikka Plant starters; Ecclesia and the Dark Dragon (2500 ATK Synchro) as a single extra-deck threat
• Turn 1 (going first): Open a Plant starter (Rikka Petal, Erica, Snowdrop, Mudan) and extend through Rikka Glamour/Konkon, then go to a Rikka Xyz; disruption is held back by hand traps.
• Turn 2 (going second): Use hand traps (Ash Blossom, Droll & Lock Bird, Maxx C, Nibiru, Evenly Matched) and negation (Hellebore, Princess, Dominus Impulse) to answer the opponent's board, then rebuild from the GY Plant recursion.
• Recovery: Recover Plant monsters from the GY through Rikka Tranquility, Rikka Petal's GY effect and Strenna's GY-to-hand effect, then re-enter the Xyz line.
• After siding: Not evaluable: the export has no side deck (side_count 0), so there is no post-side plan to assess.

Why it scores here

The Rikka list has a real Plant engine: several 3-copy Plant starters (Rikka Petal, Erica, Snowdrop, Mulcharmy Fuwalos) feed Glamour and Konkon searches toward Xyz bosses, and the archetype core is present in 13 of 16 standard cards. Interaction is the strongest part of the system: 10 hand-trap and 12 negation-text cards (Ash Blossom, Droll & Lock Bird, Maxx C, Nibiru, Hellebore, Dominus Impulse) let it answer a going-second board. Combo conversion and floor/median output cannot be measured because the export has no parseable boards, so those scores rest on text reads and are Low confidence. The deck is Illegal (Albion the Branded Dragon is Forbidden and run once), so the score is capped and reported as structural-only. Popularity and usage statistics did not earn points, and no card scores were averaged.

Dimension scores

How the score was computed

Strategy profile: Midrange primary (secondary Toolbox not blended into weights). Structural ≈ 52, Going First ≈ 55, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-12). Final formula: No reliable metagame: 0.80*Structural(52) + 0.20*TournamentReliability(45) = 50.6; minus 12 banlist-exposure modifier = 38.6; Illegal cap applied, final 30 (theoretical / structural-only)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.29 · 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 Plant engine with several 3-copy starters and searchers
• 10 hand traps and 12 negation-text cards give strong interaction on the opponent's turn
• GY recursion (Tranquility, Petal, Strenna) gives some interruption recovery
• Extra Deck covers Xyz, Synchro and Link bosses

Weaknesses

• Illegal as submitted: Albion the Branded Dragon is Forbidden
• No combo boards, so ceiling and median are unmeasured
• No side deck, so no post-side plan
• 34 off-archetype copies and 18 generic cards dilute engine coherence

Critical choke points

• Albion's illegal slot must be removed before the list can be played at all
• Tributing Plant monsters is required by several starters and recursion effects

Recommended changes

Evidence & confidence

• Verified: Legality: 48 Main / 15 Extra / 0 Side; sizes within OCG rules; one Forbidden copy (Albion); Copy limits met for all Limited and Semi-Limited cards (1 and 2 copies); Archetype purity 46% (29 exact Rikka of 63 cards), composition and usage stats present
• Inferred: Opening-hand starter probabilities (hypergeometric); Hand-trap and negation coverage read from card text; Recursion and resource estimates from card text
• Provisional: Meta Power (no dated metagame sample); Matchup and format fit (no tournament link)
• Data gaps: No parseable boards in combos_evidence: combo floor, median and ceiling are text-only No tournament link: meta share and per-pilot record absent No win-rate telemetry: going-first/second and matchup results unknown Usage statistics in_this_deck flags disagree with the cards list for Aromaseraphy Jasmine, Sacred Tree Beast Hyperyton and Teardrop the Rikka Queen (marked absent, but present in cards with 1, 3 and 2 copies); the cards list was used as source of truth No side deck in the export, so post-side evaluation is not possible Meta Power is Provisional unless a dated metagame sample is supplied
