Legality
Main 56 / Extra 15 / Side 0 — status: Illegal. 9 violation(s).
Identity & game plan
- Win condition: Synchro beatdown from the 15-card Extra Deck (Junora, Chaos Angel, Stardust, Psychic End Punisher) once the Elfnote and Power Patron engine has put a board up; Vidolium 5000 ATK Pendulum threat and Elfnote Seraphim Strelitzia, backed by hand-trap protection
- Turn 1 (going first): Open an Elfnote or Power Patron starter, use searchers to reach a Tuner and a Level 6 or 7 non-Tuner, then Synchro into a boss. Hold Ash Blossom and Ghost Belle for the opponent's first activation. Any step that depends on a forbidden card (Elfnote Tinia, Secret Village) is not legal to build and does not count
- Turn 2 (going second): Use the hand-trap suite (Ash Blossom, Ghost Belle, Effect Veiler, Droll and Lock Bird, Solemn effects) to answer the opponent's board, then rebuild through the Elfnote engine. Synchro into a boss after the interaction resolves
- Recovery: Searchers and Mulcharmy draw effects refill the hand; Stardust and Starjunk recursion rebuild the Extra Deck threat
- After siding: No Side Deck is registered (side_count 0), so there is no post-side plan in this list
Why it scores here
The deck is structurally coherent around an Elfnote and Power Patron engine that feeds a 15-card Synchro Extra Deck, and it is well stocked with searchers (18 cards, about 87% chance of at least one in a 5-card opening). Its interaction suite is broad, with 11 hand traps and 17 negation-text cards, which earns the going-second and end-board scores. The list is illegal: three forbidden cards are run, and five other cards exceed their copy limits. Under the rubric that caps the result, the 50 structural score is theoretical only. Popularity and the archetype's usage data confirm the list is real, but they did not add points. Averaging the individual card scores was not used. Floor and median output are unmeasured because there are no recorded boards, so the combo scores are inferred from card text.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 58 | P(at least one searcher in 5-card opening) about 0.87; 3 copies of the core starters; forbidden Elfnote Tinia removes a 3-copy engine piece (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 50 | 11 hand traps plus 14 tech cards give many situationally dead hands on going-first; 0 Level 0 monsters are needed to fill out the spell and trap slots (Inferred) |
| D3 | Combo Conversion & Ceiling | 40 | No parseable boards; ceiling is text-only from Junora and Chaos Angel summon effects (Inferred) |
| D4 | Combo Floor & Median Output | 35 | No combo median or power distribution exists in the export; the typical board is unknown (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 55 | 14 negation-text cards and recursion from Stardust and Starjunk give alternate lines after one disruption (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 55 | Searcher text on 18 cards and draw effects from Mulcharmy and Droll and Lock Bird refill the hand (Inferred) |
| D7 | End-Board & Interaction Quality | 62 | Dense negation and hand-trap coverage, plus Stardust and Psychic End Punisher as end-board breakers; Crystal Wing removed by the forbidden check (Inferred) |
| D8 | Going-Second & Board-Breaking Power | 60 | Going-second value rests on 11 hand traps and Solemn effects that can stop a board before it lands (Inferred) |
| D9 | Offensive Pressure & Closing Power | 60 | Vidolium at 5000 ATK and Chaos Angel at 3500 ATK give closing threats; the Extra Deck is heavy on Synchro bosses (Verified card text, Inferred impact) |
| D10 | Main Deck Efficiency & Flexibility | 50 | 56 Main Deck cards with 28 distinct cards and a large copy-limit overage; 11 hand traps cut into the engine density (Verified composition) |
| D11 | Extra Deck Efficiency & Coverage | 60 | 15 Synchro Extra Deck cards with no Fusion or Link slots; the Extra Deck is fully used and each slot has a role (Verified composition) |
| D12 | Side Deck Adaptability | 10 | side_count 0 with no Side Deck registered, so there is no post-side adaptation (Verified) |
| D13 | Matchup Coverage & Format Fit | 40 | No tournament link; archetype core present in 3 of 4 usage rows (75%); the forbidden cards make format fit unverifiable (Provisional) |
| D14 | Pilotability & Error Tolerance | 40 | Multiple Quick Effect hand traps and Synchro chains require frequent timing decisions (Inferred) |
How the score was computed
Strategy profile: Midrange. Structural ≈ 50, Going First ≈ 45, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: banlist exposure (-10). Final formula: Illegal cap applied: structural only. Uncapped 0.80*50 + 0.20*35 + (-10) = 37, then capped to 20 because the deck runs 3 Forbidden-status cards and exceeds copy limits on 5 others. Meta provisional (null).
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.87 · 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
- Searcher density (18 cards, about 87% chance of one in hand)
- Broad negation and hand-trap coverage (17 negation texts, 11 hand traps)
- Extra Deck fully used by 15 Synchro bosses with a clear end-board role
Weaknesses
- Illegal list: three forbidden cards and five copy-limit overages
- No Side Deck and no post-side plan
- Engine split across sub-archetypes (Elfnote, Power Patron, Mulcharmy, Bystial, Junk) with 0 exact-name purity
- No recorded boards, so the combo floor and ceiling are unmeasured
Critical choke points
- Forbidden Elfnote Tinia and Secret Village of the Spellcasters are engine pieces that must be removed before the list is legal
- Every Synchro line needs a Tuner plus a non-Tuner, so losing the Tuners to hand traps stalls the Extra Deck
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Elfnote Tinia x3 and Secret Village of the Spellcasters x3 | Legal engine and searcher replacements already in the same archetype (copies within the current limits) | These cards are Forbidden, so the list cannot be legal in TCG until they are removed |
| 2 | Excess copies of Elfnote Lucina, Ash Blossom & Joyous Spring, Prohibited Power Patron Portal - Terminus, Droll and Lock Bird, and the single Forbidden Called by the Grave, F.A. Dawn Dragster and Crystal Wing Synchro Dragon | Legal copies within the Limited and Semi-Limited caps | Brings every card within its copy limit and makes the deck legal to rate normally |
| 3 | A few tech slots | A Side Deck of 15 cards | Gives a post-side plan, which D12 cannot score without |
Evidence & confidence
- Verified: Illegal status and every violation listed in legality; Banlist status of each restricted card; Main 56, Extra 15, Side 0 counts; Composition: 15 Synchro, 18 searchers, 11 hand traps
- Inferred: Hypergeometric consistency (about 0.87 searcher, 0.75 hand-trap going second); Engine conflict and brick estimates from card text; Going-first and going-second plans
- Provisional: Meta Power (null, no dated metagame sample); D13 format fit
- Data gaps: No combos supplied, so combo floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and per-pilot record are absent No win-rate telemetry, so going-first and going-second splits are Inferred Meta Power is Provisional with no dated metagame sample Side Deck is empty
