Legality

Main 55 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

  • Win condition: Link-based boards from Maliss, Ars Magna Power Patron and Code Talker Link monsters, backed by Mediclius and Code Igniter, converting into 2300-3000 ATK bosses.; Medius / Theorealized Medius recursion into Power Patron Link plays, with Mulcharmy draw engines for grind.
  • Turn 1 (going first): Open with Maliss or Medius searchers, Set or Normal Summon into a Link-material path, and hold hand traps (Ash, Ghost Ogre, Nibiru, Droll) for the first opposing response.
  • Turn 2 (going second): Hold Ash Blossom, Droll & Lock Bird, Ghost Ogre and Nibiru to interrupt the opponent's first search or Summon, then rebuild a Link board from the surviving field.
  • Recovery: Mulcharmy monsters draw when the field is empty, Medius and Theorealize recover from the GY, and Maliss Link monsters can be re-summoned from the GY.
  • After siding: Not evaluable: the list runs no side deck, so there is no post-side plan.

Why it scores here

The deck is Illegal under the OCG list (Ash Blossom & Joyous Spring is run 3 times against a limit of 2), so it receives a theoretical, structural-only score capped at 25 rather than a normal final score. Structural power is about 51 on the Combo profile: the 13-card archetype core gives roughly a 76% chance of at least one core card in a 5-card opening hand (Inferred), and 12 hand-tagged interaction cards plus broad removal text make the end board and going-second interaction the strongest part of the list. The main weaknesses are the number of separate engines (Maliss, Medius, Mulcharmy, Ars Magna, Code Talker), several self-conditional effects that only work with an empty field, the absence of any recorded boards, and an empty side deck that leaves no post-side plan. Archetype usage shows Firewall Dragon, Maxx C and Accesscode Talker at high inclusion, but none are in this list, so popularity earned no points and the score does not average the individual card scores.

Dimension scores

# Dimension Score Evidence
D1 Engine Accessibility & Consistency 55 P(at least one of 13 archetype-core cards in a 5-card opening hand) ≈ 0.76; spread across several engines (Inferred)
D2 Opening-Hand Quality & Brick Management 48 12 hand-trap-tagged cards and several empty-field-conditional monsters create dead or conflicting draws; no brick rate measured (Inferred)
D3 Combo Conversion & Ceiling 50 No parseable recorded boards; ceiling is a text-only read of Power Patron and Maliss Link lines (Inferred)
D4 Combo Floor & Median Output 40 No combo evidence supplied, so median output is unknown and scored low (Provisional)
D5 Interruption Resilience & Route Redundancy 50 Redundant hand traps and two independent Link routes give some recovery after one disruption (Inferred)
D6 Resource Economy, Recovery & Grind 55 Mulcharmy draw effects and Theorealize recursion regenerate resources, but the empty-field conditions limit them (Inferred)
D7 End-Board & Interaction Quality 70 31 removal-text cards, 12 hand traps, Lightning Storm, Harpie's Feather Duster and Dimensional Fissure give layered interaction (Inferred semantic read)
D8 Going-Second & Board-Breaking Power 60 Hand traps (Ash, Ghost Ogre, Droll, Nibiru) plus Harpie's Feather Duster give strong going-second disruption; no going-second split data (Inferred)
D9 Offensive Pressure & Closing Power 50 Link bosses at 2300-3000 ATK (Mediclius 3000, Accesscode Talker 2300) and Maliss Red Ransom; no measured closing data (Inferred)
D10 Main Deck Efficiency & Flexibility 45 55 main with 33 distinct cards and many one-of tech slots; several cards have narrow archetype use (Inferred)
D11 Extra Deck Efficiency & Coverage 55 15 Extra slots: 14 Link monsters and one Xyz, spread across several engines with no single mandatory Extra Deck card (Inferred)
D12 Side Deck Adaptability 15 Side deck is empty, so there is no post-side adaptability (verified from list)
D13 Matchup Coverage & Format Fit 40 No tournament link or dated metagame sample supplied; matchup fit cannot be measured (Provisional)
D14 Pilotability & Error Tolerance 35 Multiple engines with conditional triggers and Link-chain sequencing need many decision points (Inferred)

How the score was computed

Strategy profile: Combo. Structural ≈ 51, Going First ≈ 52, Going Second ≈ 57, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: Illegal deck cap (-18); Banlist exposure (-3); Engine conflicts (-3). Final formula: Uncapped: 0.80*51 + 0.20*40 + modifiers(-6) = 43; Illegal cap applied, final = 25 (theoretical/structural only). Meta Power provisional, excluded.

Probability & combo summary

  • Opening a starter: P(≥1) ≈ 0.76 · key two-card combo ≈ — · full-brick estimate ≈ 0.24 (all Inferred)
  • Combo output: best PowerIndex —, median —, board-per-starter —
  • Turn order: 0 going-first lines vs 0 going-second lines

Strengths

  • 12 hand-trap-tagged cards give several answers to a single opposing line
  • Layered removal and board-wipe effects (Lightning Storm, Harpie's Feather Duster, Dimensional Fissure, Maliss in Underground)
  • Several Link bosses at 2300 to 3000 ATK
  • Compact 55-card main with no dead-weight Extra Deck slots

Weaknesses

  • Illegal copy count on Ash Blossom & Joyous Spring
  • Empty side deck: no post-side plan
  • No recorded combos or win data to confirm the ceiling
  • Several engines compete for the same board state

Critical choke points

  • Ash Blossom & Joyous Spring third copy must be cut before the deck can be legally played
  • Core Link lines depend on the 13-card archetype core, with about a 24% chance of none in the opening hand
  • Mulcharmy engines only work with an empty field, which conflicts with the Maliss and Medius board
Priority Remove Add Reason
1 1 copy of Ash Blossom & Joyous Spring one legal flex card (no copy-limit conflict) Clears the only copy-limit violation so the list is Legal and eligible for a normal score.
2 none up to 15 side-deck cards The side deck is empty; a side plan is needed to score D12 and to answer match-up changes.
3 one Mulcharmy copy one non-empty-field draw or search card Reduces the empty-field conflict between Mulcharmy and the Maliss/Medius board. Usage shows Maxx C at 69% inclusion but it is not in this list.

Evidence & confidence

  • Verified: Main 55, Extra 15, Side 0 against OCG size rules (40-60, 0-15, 0-15); Ash Blossom & Joyous Spring: 3 copies vs OCG Semi-Limited limit 2; Seven Limited cards each run at 1 copy, within limit; Card text for 60 distinct cards from the evidence pack
  • Inferred: Opening-hand access to the archetype core (about 0.76 at least one); Brick and conflict rates from card text; Interaction density from hand-trap and removal text; Going-first and going-second estimates
  • Provisional: Meta Power (no dated metagame sample); Matchup fit (no tournament link)
  • Data gaps: No combos supplied: floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot record absent No win-rate telemetry: going-first, going-second and matchup rates are Inferred or Unknown Meta Power provisional without a dated metagame sample Side deck empty: post-side adaptability cannot be evaluated Deck title is null in the export
