Deck — Deck Power Evaluation
Final Contextual Deck Power: 25/100 (±10 · Confidence: Medium)
| Overall score | Value |
|---|---|
| Structural Deck Power | 51 |
| Going First | 52 |
| Going Second | 57 |
| Meta Power | provisional |
| Tournament Reliability | 40 |
- Primary strategy: Combo
- Secondary strategies: Toolbox, Stun
- Format: ocg
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
Recommended changes
| 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
