Deck — Deck Power Evaluation

Final Contextual Deck Power: 25/100 (±10 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Toolbox, Tempo
• Format: tcg

Legality

Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 7 violation(s).

Identity & game plan

• Win condition: Link and Synchro boards from Power Patron and Elfnote engines, closing through Mediclius-type Link beatsticks and Ars Magna Link pressure (text-only read, Inferred); Theorealize and Medius recursion into Fusion, Synchro and Xyz boards (Inferred)
• Turn 1 (going first): Open a Pendulum or Elfnote starter, search an Elfnote or Power Patron, then Special Summon through the Elfnote Fortuna and Regina chain toward a Link Summon (Inferred from card text; no recorded boards)
• Turn 2 (going second): Hold Ash Blossom, Ghost Ogre, Skull Meister and Infinite Impermanence in hand to answer the first starter, then rebuild through the Medius and Theorealize loop (Inferred)
• Recovery: Recycle Medius and Theorealize from the GY and banishment, and use Ars Magna Spell/Trap searches to restore the engine (Inferred from text)
• After siding: Not evaluable: the deck runs no side deck (side_count 0)

Why it scores here

The deck is Illegal as built: four Forbidden cards (Called by the Grave, Crystal Wing Synchro Dragon, Elfnote Tinia, F.A. Dawn Dragster) are run, and three Limited or Semi-Limited cards exceed their copy limits. Under the rubric this is a structural-only read with a capped score, not a normal Final Contextual score. The core engine is reasonably accessible (about 91.5% chance of at least one core-group card in the opening five), and the hand-trap and searcher density gives good interaction and draw consistency. However, the list spreads across Elfnote, Power Patron, Artmage, Medius, Theorealize and Ars Magna, so only 7% of main-deck copies are the exact Ars Magna name, and no recorded boards exist to confirm a floor or median output. The score comes from consistency and interaction on the system, not from the archetype's popularity, and not from averaging card scores.

Dimension scores

How the score was computed

Strategy profile: Balanced (no recorded boards to confirm a Combo weight profile). Structural ≈ 45, Going First ≈ 42, Going Second ≈ 38, Meta = provisional, Tournament Reliability ≈ 35. Modifiers: Banlist exposure (-10); Engine conflicts (-5); Illegal cap (-3). Final formula: Illegal cap: structural-only read. Unmodified no-meta blend 0.80*45 + 0.20*35 = 43, then modifiers -18, capped to 25 (Meta provisional)

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.92 · 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

• Core engine reachable on turn one or two in most hands (about 91.5% for at least one core-group card in the opening five)
• Dense interaction: 18 hand traps and 15 negation-text cards, including Ash Blossom and Infinite Impermanence
• Searcher density (23) and Medius or Theorealize recursion sustain card flow

Weaknesses

• Illegal in TCG: four Forbidden cards and three over-limit copies
• Low archetype purity (7%) splits the engine across several sub-archetypes
• No side deck, so there is no post-side adaptability
• No recorded boards, so the combo ceiling and median are unmeasured

Critical choke points

• Forbidden cards removed would break planned lines that use Crystal Wing and F.A. Dawn Dragster
• Single Medius and Theorealize lines carry much of the recovery plan
• Elfnote Lucina at 3 copies is over its limit of 1, so it must be trimmed to be legal

Recommended changes

Evidence & confidence

• Verified: Legality is Illegal: four Forbidden cards and three over-limit copies (Limited and Semi-Limited) in the TCG list; Main deck 56 cards and Extra deck 15 cards are within the TCG size rules; Exact-name purity is 7% (5 of 71 copies); Extra Deck breakdown is Link 5, Synchro 7, Xyz 1, Fusion 2
• Observed: Usage statistics show the archetype core is present in the list, with Ash Blossom, Mulcharmy Fuwalos and Droll & Lock Bird at standard copy counts
• Inferred: Consistency of about 0.915 for the core group and 0.938 for the searcher group, from hypergeometric draws; Interaction density is high from card text (negation and removal text); Going-second hand-trap coverage of about 0.915 is a hypergeometric estimate; Turn-1 and turn-2 plans are text-based reads only
• Provisional: Meta Power is null because no dated metagame sample is supplied; Tournament reliability depends on a missing meta sample
• Data gaps: No parseable recorded boards: combo floor, median and ceiling are text-only inference No tournament link: archetype meta-share and per-pilot match record are absent No win-rate telemetry: going-first, going-second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional without a dated metagame sample The deck has no side deck, so post-side plans cannot be assessed
