Rikka Deck #771682 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

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

Identity & game plan

• Win condition: Traptrix Link/Xyz boards (Atypus, Rafflesia, Allomerus, Pinguicula) and Rikka Queen Strenna recursion into large attackers, with Sacred Tree Beast / Time Thief Redoer / ZEUS / TY-PHON as extra-deck payoffs; Hole Normal Trap disruption (Trap Hole Nightmare, Bottomless, Gravedigger, Time-Space) that converts opponent summons into card advantage
• Turn 1 (going first): Normal Summon Traptrix Mantis or Myrmeleo to search a Traptrix or Hole; Set Hole traps and hold hand traps (Ash Blossom, Droll & Lock Bird, Infinite Impermanence) for the opponent's turn
• Turn 2 (going second): Use Ash Blossom, Droll & Lock Bird, Infinite Impermanence and Gravedigger's Trap Hole to stop the first summon or effect, then rebuild a Traptrix board from the hand
• Recovery: Traptrix Pudica and Traptrix Dionaea recur Traptrix monsters and Hole traps from the GY; Rikka Glamour and Rikka Princess reload the hand
• After siding: No side deck is registered, so no post-side plan can be evaluated

Why it scores here

The deck opens through its 11-copy Traptrix and Rikka core, which gives about an 82% chance of at least one core card in a 5-card opening hand (Inferred hypergeometric estimate), and about 78% for one of its 10 searcher-text cards. Its interaction stack is the strongest part of the system: 6 hand traps, 15 removal-text cards and 10 negation-text cards let it answer summons on both turns, with the hand-trap group reaching about 65% in a 6-card going-second hand. Conversion and the median output cannot be measured because no boards were recorded, so the ceiling and floor scores rest on card text alone and are kept modest. The deck's own construction limits the score: the exact-name Rikka purity is only 9.1% and the list is spread across Traptrix, Hole, Mulcharmy and Aroma, which weakens engine coherence. The score is not based on the archetype's popularity, and it was not produced by averaging card scores. Because Ash Blossom is run at 3 copies against a limit of 2, the list is Illegal and the score is capped at 30 as a theoretical, structural-only read.

Dimension scores

How the score was computed

Strategy profile: Midrange primary; Stun is a qualitative secondary only, not blended. Structural ≈ 49, Going First ≈ 45, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: illegal_copy_limit (-12). Final formula: No reliable metagame: raw 0.80*Structural(49) + 0.20*TournamentReliability(40) = 47; modifiers -12 (over-limit Ash Blossom, Semi-Limited exposure, Limited Droll and Little Knight, no side deck); Illegal cap applied to 30

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.82 · 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: 6 hand traps, 10 negation-text and 15 removal-text cards
• Several Traptrix recursion routes for interruption resilience
• Good core access: about 82% for at least one core card in a 5-card opening hand

Weaknesses

• Illegal list: Ash Blossom is run at 3 copies against a legal limit of 2
• Low exact-archetype purity (9.1%); the deck mixes Traptrix, Hole, Mulcharmy and Aroma
• No side deck, so there is no post-side adaptation
• No recorded boards, so the conversion ceiling and median output are unmeasured

Critical choke points

• Ash Blossom at 3 copies must be cut to 2 before the list is legal
• Engine depends on Traptrix and Rikka monsters being present in the opening hand; no Rikka-only fallback

Recommended changes

Evidence & confidence

• Verified: Illegal over-limit status for Ash Blossom (3 vs 2 legal copies); Main 40, Extra 15, Side 0 are within OCG size rules; Banlist: Droll & Lock Bird and S:P Little Knight are Limited; Ash Blossom is Semi-Limited; Exact-name Rikka purity 9.1%
• Observed: Archetype composition from the deck list (Traptrix 23, Hole 8, Rikka 5 copies)
• Inferred: Core-group opening probability approx 0.82; Hand-trap going-second probability approx 0.65; Interaction breadth rating for D7
• Provisional: Meta Power (null, no dated sample); D13 matchup and format fit
• Data gaps: No combos supplied; combo floor, median and ceiling are text-only inference No tournament link; archetype meta-share and per-pilot records are absent No win-rate telemetry exists for going-first, going-second, matchups or brick rate Meta Power is Provisional unless a dated metagame sample is supplied No side deck registered, so post-side performance is unknown
