Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

  • Win condition: Sky Striker Link monsters and Mikanko Ritual/Xyz pressure, converting one starter into a Link or Xyz board; Fusion and Link finishers from the Extra Deck (Garura, Zero, Chorozo) after Sky Striker or Mikanko searches
  • Turn 1 (going first): Open a Mikanko or Sky Striker searcher with Mikanko Shinbu / Sky Striker Mobilize and convert into a Link Summon; keep Droplet or Lightning Storm for the opponent's first board
  • Turn 2 (going second): Use Forbidden Droplet, Maxx "C" and Mystical Space Typhoon to strip the opponent's first play, then rebuild with Mikanko searchers
  • Recovery: Recover spells to the GY for Sky Striker Ace effects (3+ Spells) and re-search through Mikanko Shinbu and Ohime
  • After siding: Not evaluable: no Side Deck is registered (side_count 0), so there is no post-side plan

Why it scores here

This list does not run one engine. It splits its 40 Main Deck slots across two sub-archetypes (Mikanko and Sky Striker, plus a Harpie tech package and generic staples) with only one card carrying the exact Harpie name. Its reliable opening is a searcher-heavy setup: about 82% (hypergeometric, Inferred) of openings hold at least one of the 11 searcher-text cards, but a single starter with three copies is only about 34% likely in a 5-card opening, so the engine is often live without being functional. Interaction is the deck's strongest component, with 10 removal-text and 7 negation-text cards plus Droplet, Lightning Storm and Feather Duster, although Radiant Typhoon Vision is over the limit, which makes the list illegal. No combo boards were recorded, so conversion and floor scores are text-only inference. Popularity and archetype naming earned no points, and this score is not an average of card scores; the deck is Illegal, so its final score is capped at 25.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 55 P(≥1 of a 3-copy starter in 5-card hand) ≈ 0.34; searcher-text group P(≥1 in 5) ≈ 0.82 (Inferred)
D2 Opening-Hand Quality & Brick Management 50 17 singleton slots and two competing sub-engines (Mikanko vs Sky Striker) raise conflicting-hand risk (Inferred)
D3 Combo Conversion & Ceiling 55 No recorded boards; ceiling read from text: Link/Xyz/Fusion conversions from Sky Striker and Mikanko starters (Inferred)
D4 Combo Floor & Median Output 45 No recorded boards; median likely lower given the split engines and single-card boards (Inferred)
D5 Interruption Resilience & Route Redundancy 50 Multiple recursion and searcher routes (Sky Striker Ace GY effects, Mikanko searchers) give partial redundancy (Inferred)
D6 Resource Economy, Recovery & Grind 55 Sky Striker GY effects need 3+ Spells in the GY; spell-heavy list (31 Spells) fuels this (Inferred)
D7 End-Board & Interaction Quality 60 10 removal-text and 7 negation-text cards plus Droplet, Lightning Storm, Feather Duster, Maxx "C" (Verified card text / Inferred quality)
D8 Going-Second & Board-Breaking Power 50 Going-second plan relies on Droplet, Storm and Feather Duster; no going-second combo data (Inferred)
D9 Offensive Pressure & Closing Power 45 Link boards reach 1500–2000 ATK; few piercing or direct-damage finishers in the list (Inferred)
D10 Main Deck Efficiency & Flexibility 45 40 Main with 27 distinct cards and a copy histogram of 17 singles / 7 doubles / 3 triples; diluted by off-archetype staples (Verified composition)
D11 Extra Deck Efficiency & Coverage 55 15 Extra slots: 8 Link, 5 Fusion, 2 Xyz; several Extra cards require a specific sub-archetype (Verified composition / Inferred)
D12 Side Deck Adaptability 20 No Side Deck registered (side_count 0); no post-side plan (Verified)
D13 Matchup Coverage & Format Fit 40 No tournament link or dated metagame sample; archetype meta share absent (Provisional)
D14 Pilotability & Error Tolerance 45 Two-engine plan with many conditional on-field and GY requirements; multiple decision points per turn (Inferred)

How the score was computed

Strategy profile: Toolbox. Structural ≈ 50, Going First ≈ 50, Going Second ≈ 46, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: banlist_exposure (-8); illegal_cap (-14). Final formula: Illegal cap applied. Pre-cap: 0.80*Structural(49.7) + 0.20*TournamentReliability(40) + modifiers(-8) = 39.8; capped to 25 because the deck is Illegal. Theoretical/structural only. Meta Power provisional (null).

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

  • Dense searcher and interaction package (11 searcher-text, 10 removal-text, 7 negation-text cards)
  • Extra Deck covers Link, Fusion and Xyz options from one list

Weaknesses

  • Two competing engines (Mikanko and Sky Striker) dilute each other
  • Illegal copy count on Radiant Typhoon Vision
  • No Side Deck, so no post-side plan
  • No recorded boards, so conversion cannot be verified

Critical choke points

  • Single-copy Mikanko Shinbu / Sky Striker Mobilize starters (3 copies each) carry most T1 lines
  • Radiant Typhoon Vision must be cut to 1 copy before the list is legal
Priority Remove Add Reason
1 1 copy of Radiant Typhoon Vision Any single-copy legal tech or staple Fixes the only legality violation; the deck cannot score normally while Illegal
2 Off-archetype staples (e.g. Triple Tactics Talent, Double-Edged Sword) More consistent searchers for the chosen engine Reduces the two-engine split and raises D1 and D10
3 Nothing in the Side Deck (none registered) A 15-card Side Deck of hand traps and anti-Link answers Gives D12 and the going-second plan a real post-side route

Evidence & confidence

  • Verified: Radiant Typhoon Vision: 2 copies vs Limited limit of 1 (Illegal); Main 40 / Extra 15 / Side 0 within Master Duel size rules; Card text for the 27 main and 14 extra distinct cards
  • Inferred: D1 consistency from hypergeometric estimates; D3/D4 conversion and floor from text only; D5 redundancy from searcher and recursion text; D7 interaction quality from text flags
  • Provisional: Meta Power (null); D13 matchup and format fit
  • Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN — going-first/second, matchup, brick and starter rates are Inferred or Unknown no Side Deck registered (side_count 0) Meta Power is Provisional unless a dated metagame sample is supplied
