Legality
Main 40 / Extra 15 / Side 0 — status: Illegal. 4 violation(s).
Identity & game plan
- Win condition: Radiant Typhoon Quick-Play chain into Synchro/Link boss monsters such as Crystal Clear Wing Over Synchro Dragon, Radiant Typhoon Fonix and Varuroon; Clear Wing and Speedroid Synchro beats backed by negation effects
- Turn 1 (going first): Open a Speedroid or Radiant Typhoon starter, search a Mystical Space Typhoon or Radiant Typhoon Quick-Play, then use Mystical Space Typhoon to set up a Synchro boss (Inferred from card text; no recorded boards)
- Turn 2 (going second): Use hand traps Ash Blossom, Maxx C, Droll and Radiant Typhoon Varuroon to disrupt the opponent, then rebuild through the Radiant Typhoon searchers (Inferred)
- Recovery: Radiant Typhoon Ascendance and Radiant Typhoon Vision recycle Quick-Play Spells from the GY; Mulcharmy Fuwalos refills the hand (Inferred)
- After siding: No side deck is registered, so no post-side plan exists (Verified)
Why it scores here
The deck is scored as a theoretical structure only because the list is illegal: it runs three copies of the Limited Radiant Typhoon Chant and three Forbidden cards (Auroradon, Baronne de Fleur, Albion), so the normal contextual score is capped at 30. The structural read is driven by the system, not by averaging card scores. The 3-copy Quick-Play engine gives a reasonable starter chance (P of at least one 3-copy card in a 5-card hand is about 0.34, and P of at least one searcher-text card is about 0.97), which supports the engine-accessibility and interaction scores. Four hand traps and seven tech cards add interaction depth, especially at end-board level. Combo ceiling and floor are not scored from recorded boards because none exist, and there is no tournament or side-deck data, so meta fit and side adaptability stay low and provisional. Popularity was not credited, and card scores were not averaged.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 62 | P(at least 1 of a 3-copy starter in 5 cards) = 0.34; searcher-text density across 19 cards gives a high chance of a searcher (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 55 | Four hand traps, seven tech cards and several Quick-Play Spells produce some dead or conflicting draws; no brick estimate was computed from play data (Inferred) |
| D3 | Combo Conversion & Ceiling | 45 | No recorded boards (combos_evidence.total_combos = 0); ceiling is a text-only read of Synchro and Link bosses (Inferred) |
| D4 | Combo Floor & Median Output | 40 | No recorded boards, so there is no median or power distribution; placed low by default (Provisional) |
| D5 | Interruption Resilience & Route Redundancy | 60 | Multiple Radiant Typhoon searchers and recyclers give alternative routes after a disruption (Inferred from card text) |
| D6 | Resource Economy, Recovery & Grind | 55 | Ascendance, Vision and Mulcharmy Fuwalos recycle or refill resources; Forbidden cards are removed from the count (Inferred) |
| D7 | End-Board & Interaction Quality | 70 | Varuroon, both Clear Wing negators, Baronne (illegal, excluded from the legal count) and Crystal Clear Wing Over Synchro cover board-level negation (Inferred from card text) |
| D8 | Going-Second & Board-Breaking Power | 60 | Four hand traps and multiple negators challenge a going-second board, but Forbidden boss cards are removed from the legal read (Inferred) |
| D9 | Offensive Pressure & Closing Power | 55 | Boss ATK of 3000 to 3500 (Fonix, Over Synchro) gives closing power; Forbidden cards are not counted (Verified from card stats) |
| D10 | Main Deck Efficiency & Flexibility | 60 | 21 distinct main cards in 40 slots with a 3-copy engine core; compact but with 10 single-copy cards (Verified from composition) |
| D11 | Extra Deck Efficiency & Coverage | 45 | Synchro and Link bosses fill 15 Extra slots, but Forbidden Albion, Auroradon and Baronne are illegal and reduce coverage (Verified) |
| D12 | Side Deck Adaptability | 10 | No side deck is registered (side_count 0) (Verified) |
| D13 | Matchup Coverage & Format Fit | 35 | No tournament link or dated meta sample, so matchup and format fit are Provisional |
| D14 | Pilotability & Error Tolerance | 50 | Several branching Quick-Play and Synchro sequences give moderate decision load; no examples supplied to measure it (Inferred) |
How the score was computed
Strategy profile: Combo. Structural ≈ 54, Going First ≈ 55, Going Second ≈ 58, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-12); illegal list cap (0). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers = 52.2 - 12 = 40.2, then capped at 30 because the deck is Illegal (rubric Step 2: theoretical or structural-only score)
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.34 · 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
- Quick-Play engine with multiple searchers and recyclers (Verified from card text)
- Strong end-board negation and boss stats (Verified from card text and stats)
- Four hand traps and seven tech cards give good interaction density (Verified from role tags)
Weaknesses
- Illegal list: Radiant Typhoon Chant over limit and three Forbidden cards (Verified)
- No side deck, so no post-side adaptability (Verified)
- No recorded boards, so the combo ceiling and median are unknown (Verified)
Critical choke points
- Mystical Space Typhoon is the key Quick-Play for both engine and interaction (Inferred)
- Forbidden Albion, Auroradon and Baronne are removed by the legal rule, so the deck loses boss and removal density (Verified)
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Radiant Typhoon Chant (2 extra copies beyond the Limited cap) | A legal non-Limited Radiant Typhoon card or a Quick-Play Spell | Brings the list back to the copy limit; restores a legal engine (Verified) |
| 2 | Mecha Phantom Beast Auroradon, Baronne de Fleur, Albion the Branded Dragon | Legal Synchro, Link or Fusion bosses from the current list | These are Forbidden in OCG and make the list illegal (Verified) |
| 3 | None | A side deck of up to 15 cards | A side deck is missing entirely, so post-side adaptability cannot be scored (Verified) |
Evidence & confidence
- Verified: Legality: Illegal, 40 main / 15 extra / 0 side, four copy-limit violations; Radiant Typhoon Chant 3 copies vs limit 1; three Forbidden cards; Hypergeometric draw probabilities from the main deck
- Inferred: Starter and searcher reliability from card text; Interaction density from negation and hand-trap text; Going-first and going-second plan read; Resilience and recovery ratings from text
- Provisional: Meta power (no dated meta sample); Matchup and format fit (no tournament data); Median and floor (no recorded boards)
- Data gaps: no combos supplied: 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 (going-first/second, matchup, brick/starter rates) Meta Power provisional without a dated metagame sample deck title is null
