Identity & game plan

Win condition: Extra Deck Synchro/Link boards built around Power Patron and Elfnote monsters, with Medius the Pure and Theorealize as the searcher-driven starters; Ars Magna Link-support plays and Artmage Diactorus negation-based boards
Turn 1 (going first): Normal Summon Medius the Pure or Elfnote Power Patron, search a Power Patron or Elfnote with Medius or Power Patron Portal, then build a Link or Synchro board; the Forbidden copies that would power this line cannot legally be run
Turn 2 (going second): Hold Ash Blossom, Effect Veiler, Ghost Ogre and Skull Meister as hand traps against the opponent's starter, then rebuild with Medius and Elfnote searches; the hand-trap density is the intended second-player plan
Recovery: Medius and Theorealized Medius recur from the GY and banish, and Elfnote Welcome Home and Elfnotes Rhapsodia provide some recursion
After siding: No Side Deck is registered, so no post-side plan exists in this list

Why it scores here

The deck is scored on the system, not on an average of its cards. Its searcher density (19 searcher-text cards; P(at least one searcher in a 5-card opening hand) is about 0.89) suggests the engine is accessible on turn 1 to turn 2, which carries most of the Structural score. Interaction is strong, with 17 hand-trap-tagged cards and 12 negation-text cards, giving a high chance of holding a hand trap on the second player's turn. The Extra Deck is coherent around Power Patron, Elfnote and Medius links and synchros. However, the list fails the copy limit on eight cards, including three Forbidden cards and several Limited or Semi-Limited copies, so it is Illegal and receives a capped Final score of 20 as a theoretical structural read only. No combos, usage statistics, tournament link or Side Deck are present, so the combo and matchup dimensions are text-only inference, and popularity or archetype stats did not earn any points.

Dimension scores

#	Dimension	Score	Evidence
D1	Engine Accessibility & Consistency	62	P(at least one searcher in a 5-card opening hand) is about 0.89 with 19 searcher-text cards; the core engine is accessible, but the Forbidden copies would not be legal (Inferred)
D2	Opening-Hand Quality & Brick Management	45	17 hand-trap cards and 12 Effect Monster searchers put a high share of hands in a functional state, while 3-copy Effect Monsters and Spells add redundancy, but no brick estimate exists (Inferred)
D3	Combo Conversion & Ceiling	50	Ceiling is inferred from text only, since no combos were supplied; Synchro and Link summons from Medius and Power Patron can produce a strong board (Inferred)
D4	Combo Floor & Median Output	45	Median output is unknown because no recorded boards exist; the mixed engine suggests a middling typical result (Provisional)
D5	Interruption Resilience & Route Redundancy	48	Recursion from Medius, Elfnote Welcome Home and Rhapsodia offers some route redundancy after interruption, but the engine is centred on a few starters (Inferred)
D6	Resource Economy, Recovery & Grind	50	Searchers and recursion give some grind, and Medius can recur from the GY, but the Forbidden spend cards limit this (Inferred)
D7	End-Board & Interaction Quality	55	17 hand traps, 12 negation-text cards, and Artmage Diactorus, Number 90 and Crystal Wing provide interaction layers, but the Forbidden cards weigh the score down (Inferred)
D8	Going-Second & Board-Breaking Power	40	Going-second board-breaking is unknown without combo data; Ghost Ogre, Ash Blossom and Skull Meister help the second player, but the Forbidden copies are not legal (Inferred)
D9	Offensive Pressure & Closing Power	55	Power Patron Link and Synchro monsters such as Vidolium and Mediclius give closing pressure from the Extra Deck, but no end-board data exists (Inferred)
D10	Main Deck Efficiency & Flexibility	50	56 Main Deck cards is inside the 40-60 size window, but 30 distinct cards with heavy copy counts and the illegal copies reduce efficiency (Verified)
D11	Extra Deck Efficiency & Coverage	60	Extra Deck has 15 cards with a mix of 4 Link, 9 Synchro, 1 XYZ and 1 Fusion, which gives good coverage, but the Forbidden Dharc and Crystal Wing slots reduce it (Verified)
D12	Side Deck Adaptability	20	No Side Deck is present, so post-side adaptability is unmeasured and scores low (Verified)
D13	Matchup Coverage & Format Fit	40	No tournament link, archetype usage data or dated metagame sample is available, so matchup fit is Provisional
D14	Pilotability & Error Tolerance	40	The engine has many decision points across Medius, Elfnote and Power Patron, and the hand-trap timing is nontrivial (Inferred)

How the score was computed

Strategy profile: Balanced. Structural ≈ 48, Going First ≈ 45, Going Second ≈ 42, Meta = provisional, Tournament Reliability ≈ 40. Modifiers: illegal_copy_limit (-20); banlist_exposure (-5); no_side_deck (-3). Final formula: Illegal deck: capped at 20 (theoretical/structural read only). Structural (balanced weights) = 48.4; Meta provisional and not used.

Probability & combo summary

Opening a starter: P(≥1) ≈ 0.89 · 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

Searcher density gives strong access to the engine
Extra Deck covers Link, Synchro, XYZ and Fusion summons with a coherent Power Patron and Elfnote core
Dense hand-trap and negation package for the second player

Weaknesses

Illegal under the copy limit (eight cards over), with three Forbidden cards
No Side Deck
Low archetype purity (4.2 percent exact-name) and a diffuse mix of sub-archetypes

Critical choke points

Medius the Pure as the starter that unlocks the Power Patron route
The Forbidden copies that the engine assumes

Recommended changes

Priority	Remove	Add	Reason
1	Called by the Grave, Triple Tactics Talent, Elfnote Tinia, F.A. Dawn Dragster, Crystal Wing Synchro Dragon	Legal substitutes from the same archetype or a neutral card	The deck cannot be legally entered until these Forbidden copies are removed
2	Copies above the Limited or Semi-Limited caps (Elfnote Lucina to 1, Droll & Lock Bird to 1, Ash Blossom to 2)	Legal alternates	Brings the list within the copy limits
3	None	A Side Deck of up to 15 cards	Post-side plan is absent and D12 is the weakest dimension

Evidence & confidence

Verified: Main Deck 56 cards and Extra Deck 15 cards are within size rules; Eight copy-limit violations and the Forbidden and Limited status of listed cards; No Side Deck present; Archetype spread and purity figures
Inferred: Engine accessibility from searcher hypergeometric estimates (0.8859); Hand-trap second-player estimate (0.8995); Interaction density from text and role tags; Resilience and resource estimates from card text
Provisional: Meta power (no dated metagame sample); Matchup and format fit (no tournament link)
Data gaps: no combos supplied; combo floor, median and ceiling are text-only inference no archetype usage statistics no tournament link; no archetype meta-share or pilot match record no win-rate telemetry in YGOVN no Side Deck registered Meta Power provisional unless a dated metagame sample is supplied
