Deck — Deck Power Evaluation

Final Contextual Deck Power: 0/100 (±0 · Confidence: High)

• Primary strategy: Illegal
• Secondary strategies: none
• Format: tcg

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 2 violation(s).

Identity & game plan

• Win condition: Not evaluated: deck is illegal under the TCG copy limits
• Turn 1 (going first): Not evaluated: illegal list
• Turn 2 (going second): Not evaluated: illegal list
• Recovery: Not evaluated: illegal list
• After siding: Not evaluated: no side deck and illegal list

Why it scores here

This list is illegal under TCG copy limits: Elfnote Lucina is run 3 times against a limit of 1, and Ash Blossom & Joyous Spring is run 3 times against a limit of 2. Under the rubric, an Illegal deck does not receive a normal Final Contextual score, so the structural read is withheld and the score is capped at 0 as a theoretical-only result. The deck's size (40 Main, 15 Extra, 0 Side) is within bounds and the Ars Magna package has a coherent archetype core, but popularity and usage stats were not used to lift the score, and no card scores were averaged. Combo evidence is absent (no parseable boards), so floor, median and ceiling cannot be measured. A corrected 1-copy Lucina and 2-copy Ash Blossom list would need a fresh evaluation before any score is assigned.

Dimension scores

How the score was computed

Strategy profile: not applied (illegal deck). Structural ≈ 0, Going First ≈ 0, Going Second ≈ 0, Meta = provisional, Tournament Reliability ≈ 0. Modifiers: banlist_violation (-100). Final formula: Not applied: deck is Illegal; theoretical-only structural read withheld

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.94 · key two-card combo ≈ — · full-brick estimate ≈ 0.06 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Archetype core is dense: 16 Ars Magna/Power Patron/Elfnote-linked copies give about 93.5% P(at least one core card in a 5-card opening hand), Inferred
• Hand-trap and negation suite is broad: 9 hand-trap cards and 8 negation-text cards in the Main Deck, Verified by role tags
• Extra Deck carries 15 cards with synchro, link and fusion coverage, Verified

Weaknesses

• Illegal under TCG copy limits: Elfnote Lucina at 3 vs 1 and Ash Blossom & Joyous Spring at 3 vs 2
• Exact archetype purity is 10.9%, with 49 off-archetype copies spread across 13 sub-archetypes, so engine coherence is unverified
• No combo boards, no going-first or going-second split, no tournament record

Critical choke points

• Legality: the list cannot be played in TCG as built until Lucina and Ash Blossom are cut to legal copy counts

Recommended changes

Evidence & confidence

• Verified: Legality: Elfnote Lucina 3 copies vs legal 1 (Limited); Legality: Ash Blossom & Joyous Spring 3 copies vs legal 2 (Semi-Limited); Main 40, Extra 15, Side 0 within TCG size rules; Copy histogram 10/6/6 and Extra breakdown link 4, synchro 8, xyz 1, fusion 2; Archetype exact-name purity 10.9%
• Inferred: Starter access ~93.5% in a 5-card hand from the 16-copy core proxy; Hand-trap and negation coverage from card text role tags
• Provisional: Meta and format fit: no dated metagame sample supplied
• Data gaps: no combos supplied: combo floor, median and ceiling are not measurable no tournament link: archetype meta-share and per-pilot record absent no win-rate telemetry in YGOVN Meta Power provisional without a dated metagame sample no Side Deck present, so post-side adaptability is unknown
