Final Contextual Deck Power: 40/100 (±10 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Stun, Toolbox
• Format: tcg

Legality

Main 54 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Extra Deck boss monsters (Blue-Eyes Ultimate Spirit Dragon, Neo Blue-Eyes Ultimate Dragon, Stardust Sifr, Indigo-Eyes Silver Dragon) reached through Blue-Eyes and Primite engine lines (Inferred from card text); Hand-trap and removal-supported board control leading into Synchro or Fusion summons (Inferred)
• Turn 1 (going first): Normal Summon a Level 1 Tuner (Sage with Eyes of Blue, Maiden of White, Effect Veiler) or Primite Dragon Ether Beryl, search a second engine piece, and Synchro toward a Blue-Eyes or Stardust boss (Inferred from text; no board data)
• Turn 2 (going second): Hold hand traps (Ash Blossom, Ghost Belle, Infinite Impermanence, Droll and Lock Bird, Nibiru) to answer the opponent's first board, then rebuild through Blue-Eyes White Dragon and Synchro (Inferred)
• Recovery: Recursion through Mulcharmy draw effects, Ghost Belle and Ash Blossom graveyard effects, and Master with Eyes of Blue / Sage searches for Tuners (Inferred from text)
• After siding: Not evaluable: the deck has zero Side Deck cards, so there is no post-side plan (verified from evidence)

Why it scores here

The deck is scored as a system, not as an average of its cards. Its Blue-Eyes and Primite engine pieces (about 15 core copies) give roughly 82% odds of at least one searcher or core card in a 5-card opening hand, which supports a moderate consistency read (Inferred). Its 17 hand traps and 20 removal-text cards give it breadth of interaction and several ways to survive a single disruption. The Extra Deck (synchro and fusion bosses reaching 3500 to 4500 ATK) gives it a real closing ceiling. Against that, the list is illegal: three Ash Blossom & Joyous Spring exceed the Semi-Limited limit of two, so the score is capped and labelled structural-only. There are no recorded combos, no tournament link and no side deck, so median output, post-side and matchup scores are inferred or provisional. Popularity and archetype usage did not earn points: the archetype core is only 0% exact-name purity, and off-archetype copies are 69 of 69 main-deck cards.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 56, Going First ≈ 58, Going Second ≈ 62, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-12). Final formula: Raw: 0.80*Structural(56) + 0.20*TournamentReliability(45) = 54, with Meta provisional; modifiers -12 (banlist exposure) gives 42; capped to 40 because the deck is Illegal (over copy limit), so this is a theoretical, structural-only score

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.82 · 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

• Dense hand-trap and removal-text suite (17 hand traps, 20 removal-text cards)
• Multiple searchers for Tuners and Blue-Eyes pieces (15 searcher-text cards)
• Strong Extra Deck closers at 3500 to 4500 ATK
• Good Extra Deck use across synchro, fusion, link and xyz

Weaknesses

• Illegal: three Ash Blossom & Joyous Spring against a limit of two
• No side deck, so no post-side adaptation
• Low archetype purity (0% exact-name); 69 off-archetype main-deck copies
• No recorded combos, so the median and floor are unverified

Critical choke points

• Ash Blossom & Joyous Spring is the most-run hand trap and is over the copy limit
• Tuner availability: most Synchro lines need a Tuner from a narrow set of cards

Recommended changes

Evidence & confidence

• Verified: Main 54, Extra 15, Side 0 against TCG size rules; Ash Blossom & Joyous Spring: 3 copies run, legal 2 (Semi-Limited); Limited cards at 1 copy each (Droll & Lock Bird, Solemn Judgment, Harpie's Feather Duster, Bystial Magnamhut, Bystial Druiswurm); Extra Deck composition (9 synchro, 3 link, 2 fusion, 1 xyz); Usage stats: all 9 core cards present
• Inferred: Starter consistency ≈ 0.82 with the archetype core in hand (hypergeometric); Going-first and going-second plans from card text; Interaction density and board-breaking read from text roles
• Provisional: Meta power (no dated meta sample); Matchup and format fit (no tournament link); Tournament reliability
• Data gaps: no combos supplied; combo floor, median and ceiling are text-only inference no tournament link; archetype meta-share and per-pilot match record absent no win-rate telemetry; going-first, going-second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied Side deck is empty, so post-side scoring has no data
