Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

  • Win condition: Board-breaking Kaiju Special Summons (Dogoran, Thunder King, Radian, Gameciel, Kumongous) and 2800-3300 ATK beaters, fed by the Danger! hand-reveal engine.; Link beaters (Borrelsword Dragon and Borreload Dragon, 3000 ATK) once Link material is on the field.
  • Turn 1 (going first): Open on the Danger! hand-reveal chain for card flow and a searcher line (Kyoutou Waterfront, Kashtira Fenrir); Kaiju summons are unavailable until the opponent controls a monster.
  • Turn 2 (going second): Answer the opponent's first monster with a Kaiju tribute Special Summon, protected by Ash Blossom and followed by Interrupted Kaiju Slumber to clear the board.
  • Recovery: Danger! monsters re-summon from hand whenever they are discarded, Upstart Goblin and searchers rebuild the hand, and Kaiju Slumber resets the field.
  • After siding: Not applicable: Master Duel has no side deck (side_count 0).

Why it scores here

The structural score comes from the system: the Danger! hand-reveal engine is live in about 95% of opening 5-card hands (Inferred, hypergeometric over 17 Danger! monsters), and it feeds Kaiju board-breakers and 2800-3300 ATK beaters that convert a going-second board. The score does not come from Kaiju or Danger! popularity, and card scores were not averaged. No recorded boards exist (combos_evidence total 0), so median and ceiling output are Inferred from card text and confidence stays Low. The list is split across three archetypes plus generic Links (exact-name purity 25.5%), the Extra Deck has no Kaiju Link, and Kaiju summons need an opponent monster, which caps going-first. Final 53 with a ±8 band; Meta Power is null and Tournament Reliability is Inferred.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 70 P(>=1 Danger! monster in opening 5) = 0.949 across 17 Danger! monsters; Kaiju core accessible from hand only with an opponent monster (Inferred)
D2 Opening-Hand Quality & Brick Management 58 Kaiju cards are dead when going first and only 3 Ash Blossom hand traps exist; no brick rate supplied (Inferred)
D3 Combo Conversion & Ceiling 52 No recorded boards; Danger! to draw to Kaiju/Link chain assessed from card text only (Inferred)
D4 Combo Floor & Median Output 48 Median output unknown: combos_evidence has 0 boards and usage stats carry no output data (Provisional)
D5 Interruption Resilience & Route Redundancy 62 Several independent starters (Danger!, Kaiju, Kashtira Fenrir) and 3 Ash Blossom answers; recovery not measured (Inferred)
D6 Resource Economy, Recovery & Grind 66 10 searcher-text cards with P(>=1 in opening 5) = 0.783, plus 3 Upstart Goblin for card flow (Inferred)
D7 End-Board & Interaction Quality 62 13 removal-text and 7 negation-text cards, including 3 Interrupted Kaiju Slumber for mass removal (Inferred from text)
D8 Going-Second & Board-Breaking Power 70 Kaiju tribute summons and Kaiju Slumber favor going-second boards; no going-second split recorded (Inferred from text)
D9 Offensive Pressure & Closing Power 74 Attack values 2800-3300 (Dogoran 3000, Thunder King 3300, Radian 2800) plus Borrelsword and Borreload at 3000 (Verified stats)
D10 Main Deck Efficiency & Flexibility 58 40 main cards, 20 distinct, 6 singletons; exact-name purity 25.5% across Danger!, Kaiju and generic cards (Verified)
D11 Extra Deck Efficiency & Coverage 55 15 Link Extra cards from several archetypes and generics with no Kaiju Link; Link access depends on main-deck material (Inferred)
D12 Side Deck Adaptability 40 No side deck in Master Duel (side_count 0); adaptation limited to in-game choices (Provisional)
D13 Matchup Coverage & Format Fit 50 No tournament link and no archetype meta-share; format fit cannot be measured (Provisional)
D14 Pilotability & Error Tolerance 45 Multi-step conditional summons (tribute opponent monsters, one Kaiju per control, Danger! reveal chains) raise decision load (Inferred)

How the score was computed

Strategy profile: Midrange. Structural ≈ 60, Going First ≈ 52, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 56. Modifiers: Engine conflict across archetypes (-3); Kaiju summon needs an opponent monster (-2); No Kaiju Link in Extra Deck (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional): 0.80*60.09 + 0.20*56 - 6 = 53.27

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.95 · 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

  • Danger! engine is live in roughly 95% of opening 5-card hands (Inferred)
  • Kaiju tribute summons and Interrupted Kaiju Slumber convert a going-second board
  • Several high-ATK beaters: Thunder King 3300, Dogoran 3000, Borrelsword 3000, Radian 2800
  • Redundant card flow: 3 Upstart Goblin, 10 searcher-text cards, Danger! draw on summon

Weaknesses

  • Three archetypes plus generics: exact-name purity 25.5%, so engine coherence is weak
  • Kaiju summons are dead going first until the opponent controls a monster
  • Extra Deck has no Kaiju Link; Link access depends on other archetypes
  • Only 3 hand traps (Ash Blossom), so going-second interaction is thin
  • No recorded boards, so the combo ceiling and median are not measured

Critical choke points

  • Opening hand with no Danger! monster (about 5% of 5-card hands) and no Kaiju-compatible board for a going-first opponent
  • Single hand-trap type (Ash Blossom x3) against a going-second opponent's first response
Priority Remove Add Reason
1 1 Upstart Goblin 1 extra copy of Danger! Chupacabra or Danger! Ogopogo Raises Danger! starter density, the most accessible engine, without adding dead cards to the opening hand
2 Security Dragon (Extra) Extra Deck slot for a Knightmare or Borrel Link that uses Danger! monsters as material Improves Extra Deck coherence with the main-deck engine; Security Dragon has the weakest archetype link (Inferred)

Evidence & confidence

  • Verified: Legal in Master Duel: 40 main, 15 extra, 0 side, all 35 distinct cards Unlimited; Attack values and copy counts from the card list; Archetype spread: Danger! 18, Kaiju 14, generic 14, others 9
  • Inferred: Danger! starter P(>=1 in opening 5) = 0.949; Kaiju summons require an opponent monster, so they are dead going first; Engine conflict and Link access from card text
  • Provisional: Meta Power is null; no dated metagame sample; Side-deck and matchup scores are not measurable in Master Duel; Tournament Reliability is an estimate with no tournament data
  • 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/second, matchup, brick, starter or OTK rates) Meta Power is Provisional unless a dated metagame sample is supplied Deck title is null Conflict in source data: usage_statistics marks S:P Little Knight (ref 29301450) as missing, but the card list includes it in the Extra Deck; this evaluation trusts the card list, so core coverage may be 6/6, not 5/6
