Legality

Main 55 / Extra 15 / Side 0 — status: Illegal. 2 violation(s).

Identity & game plan

  • Win condition: Synchro and Fusion boss monsters (Gorz, Absolute Zero, Stardust Dragon, Thought Ruler Archfiend) supported by removal and tribute-summon monarchs; Monarch tribute-summon removal (Caius, Raiza) converting into direct attacks
  • Turn 1 (going first): Open a starter from Swap Frog, Treeborn Frog, Dupe Frog or E-Emergency Call, then Normal Summon or Tribute into a Synchro or Fusion boss
  • Turn 2 (going second): Use hand traps (D.D. Crow, Battle Fader, Gorz Special Summon) to stop an opposing board, then rebuild with removal and a boss
  • Recovery: Recover through Dupe Frog and Treeborn Frog recursion from the Graveyard and Elemental HERO search effects
  • After siding: Not evaluable: side deck is empty (0 cards), so no post-side plan exists in the export

Why it scores here

The deck is scored on its structure, not its card quality, and it is capped low because it is Illegal in OCG: three Forbidden Substitoad and one Forbidden Trap Dustshoot exceed the copy limit. Starter access is thin, since each 3-copy starter has about a 25% chance of appearing in a 5-card opening hand (Inferred), and the deck mixes Monarch, Elemental HERO, Frog, Junk and Synchro support with only 5 exact Monarch copies (7.1% exact-name purity). Removal and hand-trap density (22 removal-text cards, 3 hand traps) gives it a reasonable end-board interaction profile, and the Synchro and Fusion bosses give it closing power. No combo boards, usage statistics, tournament data or side deck exist, so the floor, median and ceiling are text-only inferences and no matchup evidence is available. Popularity and archetype share did not earn points, and card scores were not averaged into the deck score.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 45 P(at least 1 of a 3-copy starter in a 5-card hand) ≈ 0.25; searcher group P(≥1 in hand) ≈ 0.39; no usage-stat core to compare against (Inferred)
D2 Opening-Hand Quality & Brick Management 50 55 main-deck cards across 35 distinct, with 22 singletons and a mixed-archetype spread; brick risk moderate and not measured (Inferred)
D3 Combo Conversion & Ceiling 40 No parseable boards in the export; ceiling is text-only inference from Gorz, Absolute Zero and the Monarch removal line (Inferred)
D4 Combo Floor & Median Output 35 No recorded boards, so the median is unknown and estimated low from the mixed archetype engine (Inferred)
D5 Interruption Resilience & Route Redundancy 45 Frog recursion (Treeborn, Dupe Frog) and HERO search give some redundancy, but there is no independent second line in evidence (Inferred)
D6 Resource Economy, Recovery & Grind 45 Recursion and search text is present (Dupe Frog, Treeborn Frog, E-Emergency Call); resource signature not measured (Inferred)
D7 End-Board & Interaction Quality 55 22 removal-text cards, Mirror Force, Heavy Storm and Brain Control plus 3 hand traps; interaction density not measured (Inferred)
D8 Going-Second & Board-Breaking Power 50 Hand traps and Gorz Special Summon offer some going-second answers; no going-second split data available (Inferred)
D9 Offensive Pressure & Closing Power 55 Gorz 2700 ATK, Absolute Zero 2500, Stardust Dragon 2500, Thought Ruler Archfiend 2700 give closing power, limited by the tribute and fusion requirements (Inferred)
D10 Main Deck Efficiency & Flexibility 40 55-card main within the 40-60 OCG range, but 35 distinct cards and 65 off-archetype copies lower coherence (verified size, Inferred coherence)
D11 Extra Deck Efficiency & Coverage 55 Extra Deck is 4 Fusion + 11 Synchro with mixed archetypes, giving flexibility but no clear single engine (verified breakdown, Inferred)
D12 Side Deck Adaptability 20 Side deck is empty (0 cards), so no adaptability is possible (verified)
D13 Matchup Coverage & Format Fit 40 No tournament link, meta-share or dated metagame sample; Provisional (Provisional)
D14 Pilotability & Error Tolerance 45 Several multi-step lines (tribute summons, Fusion material, Synchro chains) across three archetypes raise the skill floor (Inferred)

How the score was computed

Strategy profile: Toolbox. Structural ≈ 45, Going First ≈ 40, Going Second ≈ 44, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: Banlist exposure (-10); Engine conflicts (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) + ContextModifiers(-12) = 43.2 - 12 ≈ 31; theoretical/structural-only because the list is Illegal

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.25 · 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

  • Heavy removal and interaction text across the list (22 removal-text cards)
  • Three hand traps (D.D. Crow, Battle Fader, Gorz) for going-second disruption
  • Strong boss monsters in the Extra Deck (Gorz, Absolute Zero, Stardust Dragon, Thought Ruler Archfiend)

Weaknesses

  • Illegal in OCG: Forbidden Substitoad x3 and Trap Dustshoot x1
  • Low archetype purity (7.1%) with three or more competing engines
  • Empty side deck, so no post-side plan
  • No recorded combos, so the consistency and combo output cannot be verified

Critical choke points

  • Starter access depends on 3-copy cards with about a 25% opening-hand chance each
  • Monarch tribute summons require a second monster on the field to tribute
  • Extra Deck bosses depend on Fusion or Synchro material already present
Priority Remove Add Reason
1 Substitoad x3 and Trap Dustshoot x1 Legal, archetype-consistent replacements that fit the current engine The deck is Illegal in OCG as built, so no normal score is valid until the list is legal
2 Off-archetype singletons with no synergy Cards that reinforce one engine (Monarch, Frog or HERO) Raising exact-name purity from 7.1% would reduce brick and conflicting-engine risk
3 None A 5 to 15 card side deck An empty side deck gives no post-side adaptability (D12)

Evidence & confidence

  • Verified: Substitoad x3 and Trap Dustshoot x1 are Forbidden in OCG; the list is Illegal; Main 55 cards and Extra 15 cards are within the OCG size rules; Side deck is empty (0 cards); Extra Deck is 4 Fusion and 11 Synchro; Exact-name archetype purity is 7.1%
  • Inferred: Opening-hand starter probabilities (about 25% for 3-copy cards in a 5-card hand); Consistency, brick and interaction density estimates; Ceiling and floor are text-only inferences from card text
  • Provisional: Meta power (no dated metagame sample); Matchup format fit
  • Data gaps: No combos supplied, so combo floor, median and ceiling are text-only inference No archetype usage statistics, so core and meta-standard comparison is unavailable No tournament link, so archetype meta-share and per-pilot records are absent No side deck, so post-side evaluation is not possible No win-rate telemetry exists, so going-first, going-second and matchup signals are unknown Meta power is Provisional unless a dated metagame sample is supplied
