Legality
Main 40 / Extra 2 / Side 0 — status: Legal.
Identity & game plan
- Win condition: Level 2 beatdown: Spright Gamma Burst gives +1400 ATK to all Level/Rank/Link 2 monsters, and Gigantic Spright's doubled ATK carries the closing turn.; Spright Elf and Gigantic Spright as Extra-Deck boards that keep the Level 2 engine going.
- Turn 1 (going first): Open with Spright Starter, Ipiria or Nimble Beaver to get the first Level 2 monster out, then Spright Jet or Spright Blue to search and extend into Gamma Burst and Gigantic Spright.
- Turn 2 (going second): Use Spright Carrot or Spright Red (tribute-negate) to protect the first Level 2 monster, then convert with Cosmic Cyclone, Forbidden Lance or Spright Double Cross.
- Recovery: Re-use Spright Gamma Burst and Spright Smashers from the GY and rebuild the Level 2 board with searchers (Jet and Blue).
- After siding: None: the deck runs no Side Deck, so there is no post-side adjustment.
Why it scores here
The deck opens reliably: 9 cards (Spright Starter, Ipiria, Nimble Beaver) can start the Level 2 engine, giving roughly a 74% chance of at least one in a going-first 5-card hand and about 81% going second (hypergeometric, Inferred). Once the engine is live, 21 Level 2 monsters, 6 searcher and 6 negation/protection cards keep it moving after one interruption, and 16 removal-text cards provide interaction that is layered but has no hand traps. The score comes from consistency, the Level 2 engine, and interaction treated as one system; the popularity of the Spright archetype and the average power of its cards did not earn points. Weak points are the absence of a Side Deck, three Dark Holes that wipe the deck's own engine, and very low ATK on most of the Level 2 monsters, so the closing power depends on Gamma Burst and Gigantic Spright. There is no combo data or tournament context, so the ceiling and median scores are text-based estimates and the band is wide.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 66 | P(>=1 of 9 starter-capable cards in going-first 5) ≈ 0.74; P(>=1 in going-second 6) ≈ 0.81; Spright Starter and Level 2 normal summons bootstrap the engine (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 58 | 21 Level 2 monsters and 6 searchers keep most hands functional, but 3 Dark Hole and 3 Forbidden Lance are dead or conflicting in many hands (Inferred) |
| D3 | Combo Conversion & Ceiling | 60 | Gamma Burst, Gigantic Spright and Spright Elf can turn a Level 2 board into a large, multi-threat board; no recorded boards to confirm the ceiling (Inferred) |
| D4 | Combo Floor & Median Output | 52 | No combo data, so the median is an estimate from text alone; the median probably sits well below the ceiling (Inferred, Provisional) |
| D5 | Interruption Resilience & Route Redundancy | 62 | Starter, Ipiria and Nimble Beaver give three bootstrap routes, and Carrot/Red negation plus Jet/Blue searchers give recovery after one hit (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 60 | Starter costs LP equal to the summoned monster's ATK and Cosmic Cyclone costs 1000 LP, but Gamma Burst and Smashers recur from the GY (Inferred from card text) |
| D7 | End-Board & Interaction Quality | 64 | 16 removal-text cards plus 6 negation-text cards give layered interaction (Verified card text, Inferred quality); no hand traps (Verified flags) |
| D8 | Going-Second & Board-Breaking Power | 52 | Carrot/Red negation at Quick Effect and Dark Hole help against an established board, but the deck has no hand traps and the going-second split is unknown (Inferred) |
| D9 | Offensive Pressure & Closing Power | 60 | Low-ATK Level 2 attackers (1100–1400) rely on Gamma Burst +1400 and Gigantic Spright's doubled ATK to close (Verified stats, Inferred pressure) |
| D10 | Main Deck Efficiency & Flexibility | 78 | 14 distinct main-deck cards, 12 of them at 3 copies, 40 cards with no filler slots (Verified composition) |
| D11 | Extra Deck Efficiency & Coverage | 60 | Only 2 Extra Deck cards (Spright Elf, Gigantic Spright), both on-engine and no flex slots left unused (Verified composition, Inferred coverage) |
| D12 | Side Deck Adaptability | 15 | No Side Deck at all (Verified Side Deck size 0), so there is no post-side adaptability (Verified) |
| D13 | Matchup Coverage & Format Fit | 50 | No tournament data, no dated meta sample, and the usage stats belong to a different archetype family, so no matchup fit can be scored (Provisional) |
| D14 | Pilotability & Error Tolerance | 62 | Engine needs Level 2 tracking, Starter's LP cost and tribute decisions on Carrot/Red, which is a moderate step count (Inferred) |
How the score was computed
Strategy profile: Combo. Structural ≈ 60, Going First ≈ 62, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 55. Modifiers: engine compactness (2); no side deck (-3); engine conflict (Dark Hole) (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.74 · key two-card combo ≈ — · full-brick estimate ≈ 0.26 (all Inferred)
- Combo output: best PowerIndex —, median —, board-per-starter —
- Turn order: 0 going-first lines vs 0 going-second lines
Strengths
- Nine bootstrap cards for the Level 2 engine, with a high chance of a going-first start
- Compact 14-card main with three copies of most cards
- Layered interaction through Carrot/Red negation, Smashers, Cosmic Cyclone, Forbidden Lance and Double Cross
Weaknesses
- No Side Deck, so no post-side plan
- Three Dark Holes wipe the deck's own Level 2 board
- No hand traps, which makes going second weak
- Low ATK on most Level 2 attackers
Critical choke points
- Spright Starter, Ipiria or Nimble Beaver being in the opening hand; without one there is no engine
- The first Level 2 monster being removed before the engine is live
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | 1 Dark Hole | 1 Spright card or a hand trap if the format allows | Dark Hole wipes the deck's own Level 2 board and has no synergy with the engine |
| 2 | 1 Forbidden Lance | Side Deck slot (e.g. hand trap or board breaker) | Lance only trims 800 ATK and adds no engine value; a Side Deck slot would give post-side flexibility |
Evidence & confidence
- Verified: Legality: 40 main, 2 extra, 0 side; all cards Unlimited and within copy limits; Card text and stats from the export; Copy histogram: 12 cards at 3, 2 cards at 2
- Inferred: Bootstrap probabilities (≈0.74 going first, ≈0.81 going second); Engine conflict from Dark Hole; Pressure and interaction quality read from text
- Provisional: Meta power (no dated sample); Matchup fit (no tournament context)
- Data gaps: No combos supplied: combo floor, median and ceiling are text-only inference No tournament link: meta-share and per-pilot record absent No win-rate telemetry for going-first/second, matchup or brick rates Usage stats belong to a different archetype family (Yummy/Forbidden core) and do not describe this Spright list Export archetype label 'Forbidden' conflicts with the actual Spright engine No Side Deck, so D12 cannot be measured from data
