Legality
Main 58 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).
Identity & game plan
- Win condition: Board disruption and Link/Xyz pressure from Traptrix and Hole-based interaction; no single reliable finisher is evidenced; Rikka and Therion engine bodies providing recursion and extra pressure, which are sparsely supported in this list
- Turn 1 (going first): Open on a Traptrix/Mulcharmy starter, Normal Summon for a searcher, and hold hand traps and Trap Holes for the opponent's first summon
- Turn 2 (going second): Use hand traps (Ash Blossom, Infinite Impermanence, Nibiru, Evenly Matched, Droll & Lock Bird) to slow the opponent's first summons and follow with Trap Hole floodgates
- Recovery: Search via Traptrix Myrmeleo and Pudica, Therion Discolosseum, or Mardel and rebuild the Link line from Traptrix Sera or Atypus
- After siding: Not evaluable: side deck is empty (0 cards), so no post-side plan can be assessed
Why it scores here
The deck is illegal as submitted: three copies of Ash Blossom & Joyous Spring exceed the OCG Semi-Limited limit of two, so this is a theoretical, structural-only read capped low. Its strength is interaction density, with 13 hand traps and about 21 removal-text cards, and it reliably has some hand trap in opening hands (about 0.80 going second). Its engine is weak: the archetype-purity check gives 5.5 percent exact-name purity, with 69 off-archetype copies spread across Traptrix, Hole, and Mulcharmy, so the Rikka core (Glamour, Petal, Sheet) is absent. No combos were supplied, so the ceiling and median are text-only inference and are not scored as evidence. Popularity and usage stats were not used to raise the score, and card scores were not averaged.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 45 | P(at least one searcher-text card in a 5-card hand) is about 0.76 across 14 searcher-text cards; the Rikka engine core is missing, so the live engine is Traptrix-based (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 40 | Redundant hand traps and Trap Holes give functional hands, but 17 tech and 13 hand-trap cards mean many hands lack an engine starter (Inferred) |
| D3 | Combo Conversion & Ceiling | 30 | No recorded combo boards exist (total combos 0), so conversion is a text-only read of Traptrix link and Xyz lines (Inferred) |
| D4 | Combo Floor & Median Output | 30 | Median output is unobserved; combo data is empty, so this is a floor judgment from card text only (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 45 | Several independent disruption routes exist (hand traps, Trap Holes, Traptrix recursion), but no route was verified against real boards (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 40 | Recursion through Traptrix GY effects and search through Therion Discolosseum is present, but Rikka recovery is missing (Inferred) |
| D7 | End-Board & Interaction Quality | 65 | Interaction density is high: 13 hand traps, 21 removal-text cards, and multiple negate or floodgate effects including Floodgate Trap Hole (Inferred from card text) |
| D8 | Going-Second & Board-Breaking Power | 50 | Going-second board breaking relies on Lightning Storm, Harpie's Feather Duster, and Trap Holes against an established board; no going-second combo data exists (Inferred) |
| D9 | Offensive Pressure & Closing Power | 45 | Closing power is limited: the Link and Xyz finishers (Traptrix Rafflesia, Pinguicula, Allomerus, Teardrop) are spread across many single copies and no recorded end-board ATK data exists (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 45 | 58 Main Deck cards is legal size, but Ash Blossom is run at 3 copies, which is illegal, and 69 off-archetype copies dilute the engine (Observed structural count) |
| D11 | Extra Deck Efficiency & Coverage | 50 | The 15-card Extra Deck mixes Traptrix, Rikka, Aroma, Code Talker, and P-series Link and Xyz monsters with one copy each, giving broad but unfocused coverage (Verified count, Inferred quality) |
| D12 | Side Deck Adaptability | 30 | The Side Deck is empty (0 cards), so no adaptability can be credited (Verified; post-side performance Provisional) |
| D13 | Matchup Coverage & Format Fit | 20 | No tournament link, no dated meta sample, and Rikka archetype share is unavailable; this is Provisional |
| D14 | Pilotability & Error Tolerance | 35 | Several branching Trap Hole and Traptrix sequences, plus hand-trap timing decisions, make the deck demanding to pilot (Inferred) |
How the score was computed
Strategy profile: Stun primary with Toolbox secondary; no meta sample, so D13 is retained at its Stun weight but scored Provisional. Structural ≈ 41, Going First ≈ 40, Going Second ≈ 42, Meta = provisional, Tournament Reliability ≈ 30. Modifiers: banlist exposure (-6); engine conflict (-4). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional; Illegal cap applied)
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.76 · key two-card combo ≈ — · full-brick estimate ≈ 0.24 (all Inferred)
- Combo output: best PowerIndex —, median —, board-per-starter —
- Turn order: 0 going-first lines vs 0 going-second lines
Strengths
- Dense hand-trap and Trap Hole interaction (13 hand traps, 21 removal-text cards)
- Hypergeometric starter access of about 0.76 in a 5-card hand for searcher-text cards
- Broad Link and Xyz coverage in the Extra Deck with Traptrix Sera and Atypus as Link anchors
Weaknesses
- Illegal as submitted: Ash Blossom & Joyous Spring at 3 copies exceeds the OCG limit of 2
- Low archetype purity (5.5 percent) with the Rikka core largely missing
- No side deck, so no post-side plan and no answer to format shifts
- Many single-copy staples dilute the list; 12 cards run 1 copy and 12 run 3
Critical choke points
- Ash Blossom & Joyous Spring copy count must be cut to 2 before the list is legal
- Traptrix Myrmeleo and Pudica are the main searchers; a missing searcher leaves hands with interaction but no engine
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | One copy of Ash Blossom & Joyous Spring | A non-restricted card of the same role, or a Traptrix or Hole staple | Brings the deck to legal copy limits, which is a precondition for any normal score |
| 2 | Off-archetype single-copy tech cards such as Harpie's Feather Duster or Therion Discolosseum if the Rikka core is not being built | Rikka Glamour, Rikka Petal, or Rikka Sheet if the deck is to be a true Rikka build | Raises archetype purity and engine coherence; the current engine splits across three sub-archetypes |
| 3 | None | A side deck of 5 to 15 cards | A zero-card side deck gives no post-side plan, and D12 is set to 30 for that reason |
Evidence & confidence
- Verified: Main Deck 58 cards and Extra Deck 15 cards, both within OCG size rules; Ash Blossom & Joyous Spring is at 3 copies against a legal limit of 2 (illegal); Droll & Lock Bird, Harpie's Feather Duster, and S:P Little Knight are each at 1 copy against a Limited limit of 1; Archetype purity is 5.5 percent with 69 off-archetype copies
- Observed: Copy histogram: 12 cards at 1 copy, 5 at 2, 12 at 3; Core Rikka presence: 6 of 24 usage-stat core cards (25 percent)
- Inferred: Starter access about 0.76 in a 5-card hand (hypergeometric estimate from the evidence); Hand-trap presence about 0.80 going second; Brick rate about 0.24 for the archetype-core group; Primary strategy Stun from hand-trap and Trap Hole density
- Provisional: Meta Power (no dated metagame sample); Matchup fit (no tournament link or dated sample); Side-deck adaptability (no side deck)
- Data gaps: No combos supplied: combo floor, median, and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record are absent No win-rate telemetry: going-first, going-second, matchup, and brick rates are Inferred or Unknown No side deck: post-side adaptability cannot be scored Deck title is null, so the deck is identified only by its archetype and id Meta Power is Provisional unless a dated metagame sample is supplied
