Rikka Deck #453199 — Yu-Gi-Oh! TCG

Rikka Hybrid Multi-Engine — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±5 · Confidence: Low)

• Primary strategy: Combo
• Secondary strategies: Midrange, Control
• Format: tcg

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Build an end-board with multiple negation effects (Rikka Princess, Therion King Regulus, Sacred Tree Beast Hyperyton) plus resource advantage through chain-searching multiple plant engines; Grind through resource regeneration (Lily Borea equipment, Aromalilith Rosemary LP-gain trigger, Ragnaraika Bloom boost) and secondary layers of disruption
• Turn 1 (going first): Activate multiple starters (Princess, Glamour, Lily Borea, Evil Seed) to search and extend into Rikka Queen Strenna, Aromaseraphy Jasmine, or Teardrop Queen; establish negation layer and protection
• Turn 2 (going second): Use 2x Evenly Matched as hand-trap defense; limited board-breaker density limits efficacy without additional Fusion Summon lines from Aroma Blend
• Recovery: Recursion through GY-targeted Lily Borea equip effect, Ragnaraika Samurai Beetle return from GY after Ragnaraika Link Summon, Sunavalon Dryas recovery from GY when used as Sunseed Genius Loci material
• After siding: No side deck present (0/15 slots); cannot adapt post-game-1 in best-of-3 format

Why it scores here

**EVALUATION IS THEORETICAL/STRUCTURAL ONLY — THIS DECK IS ILLEGAL AND CANNOT BE PLAYED COMPETITIVELY.** The deck runs one copy of Naturia Rosewhip, which is Forbidden in the TCG format (0 legal copies). Structurally, if legal, the deck would open consistent multi-engine lines through six 3-copy starters (Rikka Princess, Unexpected Dai, Sunseed Genius Loci, Rikka Glamour, Therion Lily Borea, Ragnaraika the Evil Seed) and fourteen searchers (P≥1 searcher ≈ 90%), building boards with negation and disruption. However, the 0% match to the established Rikka core-card meta, absence of combo data, lack of side-deck tools, and critical legality violation combine to severely constrain its viability. The primary strength would be engine redundancy and searcher density; the primary weakness is the Forbidden card that renders competitive play impossible.

Dimension scores

How the score was computed

Strategy profile: Balanced. Structural ≈ 58, Going First ≈ 64, Going Second ≈ 48, Meta = provisional, Tournament Reliability ≈ 32. Modifiers: Forbidden card (Naturia Rosewhip) (-20); No side deck (-5); Zero meta representation (core cards) (-3). Final formula: Illegal deck — evaluated structurally only. Base structural 58, penalized by -28 for Forbidden card violation, zero side deck, and unverifiable meta position. No normal contextual scoring applies.

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.95 · key two-card combo ≈ — · full-brick estimate ≈ 0.08 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• High consistency via six 3-copy starters + fourteen searchers
• Multiple independent engine lines (Rikka, Aroma, Ragnaraika, Therion, Sunavalon/Sunvine) reduce single choke-point dependency
• Negation layer via Rikka Princess, Therion King Regulus, Sacred Tree Beast Hyperyton + Teardrop Queen Tribute effect
• Resource regeneration through Lily Borea equip, Aromalilith Rosemary LP-triggered summon, Ragnaraika Bloom boost

Weaknesses

• ILLEGAL: Naturia Rosewhip is Forbidden in TCG format — deck cannot be played competitively
• Zero side deck (0/15 slots) — no post-game-1 adaptability
• No combo data provided; actual board ceiling and median output unverified
• Only 2 hand traps (Evenly Matched x2); weak going-second defensive capability
• Limited offensive pressure — highest ATK is 2800 with no piercing/direct damage text
• 0% core-card representation from established meta Rikka list; rogue/experimental positioning
• Single-copy flex cards (Lonefire Blossom, Mudan, Petal, etc.) reduce recovery redundancy post-disruption

Critical choke points

• Naturia Rosewhip (Forbidden) — makes entire deck illegal; single card invalidates all competitive play
• Limited hand-trap density + weak board-breaker suite make going-second plan vulnerable
• No side deck prevents tactical pivots in game 2/3 of best-of-3 match
• Multiple one-copy flex cards create opening-hand variance despite high searcher density

Recommended changes

Evidence & confidence

• Verified: Legality status: Illegal (Naturia Rosewhip forbidden); Main/Extra/Side deck sizes: 40/15/0 (within TCG size rules except for forbidden card); Restricted cards: Sunavalon Dryas (Limited, 1 run), Sunvine Healer (Limited, 1 run) — both within legal limits; Composition: 24 distinct main / 12 distinct extra / 0 side; Extra deck breakdown: 10 Link, 4 Xyz, 1 Fusion
• Inferred: Consistency: Six 3-copy starters + 14 searchers yield P(≥1 starter in hand 5) > 0.90 (hypergeometric); Primary strategy: Combo (multi-engine searcher density, board-building focus); Ceiling (D3): Multiple negation sources + resource layers suggest moderate ceiling (unverified without combo data); Median (D4): Estimated conservatively at 58 due to engine diversity but limited redundancy on flex 1-2-copy cards; Resilience (D5): Six independent engines moderate disruption recovery; limited single-copy redundancy constrains secondary lines; Interaction (D7): Four negation-text cards plus Teardrop Queen Tribute effect; reasonable layering without quantified board state; Going-Second (D8): Only 2 hand traps + limited board-breaker density suggests ~48 score; Closing Power (D9): 2800 max ATK (1 copy Therion King Regulus); no piercing/direct damage text; Pilotability (D14): Multiple independent engines suggest moderate decision complexity; no step-count data available
• Provisional: Meta Power: null (no tournament context; 0% core-card representation from established Rikka meta suggests rogue positioning); Matchup Coverage (D13): No dated metagame sample; archetype meta-share unknown; Format Fit: Cannot be verified until Forbidden card is removed and legality established
• Data gaps: Critical: Naturia Rosewhip is Forbidden; deck cannot be legally evaluated as a competition piece No combos supplied — all combo ceiling/floor/median claims are text-based inference, not observed game state No tournament context — archetype meta-share, per-pilot match record, and format win-rate absent No win-rate telemetry in YGOVN — going-first/second brick rates, matchup specifics, game-level statistics unavailable No side deck (0/15 slots) — post-game-1 plan unexamined No guides attached — strategic intent and pilot expertise undocumented Usage statistics appear to be for a Traptrix-Rikka variant (100% inclusion on Traptrix cards); this deck matches 0% of that core, suggesting a completely different build philosophy
