Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±10 · Confidence: Low)

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

Legality

Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Sacred Beast Level 10 Special Summons (Calamity of the Sacred Beasts, Infinity of the Sacred Beasts) reaching 4000 ATK, backed by The Chaotic Phantasmal Sacred Beasts (5000 ATK) and Thunder Dragon Colossus (2600 ATK).; Link beatdown through Firewall Dragon, Allied Code Talker @Ignister and Codebreaker Virus Berserker, with Mulcharmy draw pressure.
• Turn 1 (going first): Open Sacred Beast searchers (Sacred Beasts Released, Thunderclap, Card of the Soul) to find a Level 10 Sacred Beast, summon it through Martyr or Summoner, and protect the line with Ash Blossom and Effect Veiler.
• Turn 2 (going second): Hold hand traps (Nibiru, Skull Meister, Effect Veiler, Droll & Lock Bird, Ghost Ogre & Snow Rabbit) to answer the opponent's opening, then rebuild Sacred Beast monsters from the GY through Martyr and Fallen Paradise.
• Recovery: Abyss of the Sacred Beasts and Fallen Paradise recycle Sacred Beast monsters from the GY; Mulcharmy Fuwalos and Purulia draw cards once the field is empty.
• After siding: No side deck is registered (Side Deck size 0), so no post-side plan can be scored.

Why it scores here

The deck's engine opens reliably: the 34-copy Sacred Beast/Phantasm core has a roughly 99% chance of at least one card in a 5-card opening hand, and the three searchers (Released, Thunderclap, Card of the Soul) add redundancy (Inferred). Its conversion ceiling depends on Level 10 Sacred Beast summons reaching 4000+ ATK boards, but no recorded boards exist, so the ceiling is text-only inference and the median is unknown. Interaction is the strongest part of the system: 19 hand-trap-tagged cards and roughly 10 negation texts give high going-second answer density (Inferred), while the lack of a side deck and any tournament or win-rate data keeps the score low. The score comes from consistency, interaction and system structure, not from averaging card scores or from Phantasm Spiral's popularity. The deck is illegal as built, because it runs 3 copies of Ash Blossom & Joyous Spring against a Semi-Limited limit of 2, so the Final Contextual score is capped and the evaluation is structural-only.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 58, Going First ≈ 52, Going Second ≈ 66, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: illegal-copy-limit cap (-25); dependence on one Extra-Deck card (0); no side deck (0). Final formula: Illegal cap: 0.80*Structural(58) + 0.20*TournamentReliability(45) = 55 before cap; Illegal decks receive no normal Final Contextual score, so the result is capped to 30 and labelled structural-only. Meta Power is null (Provisional).

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.25 · 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

• Very high archetype core density (34 copies), so the engine is nearly always present in hand.
• Layered interaction: 19 hand-trap tags plus negation and removal text gives strong going-second answers.
• Multiple Sacred Beast recursion routes (Martyr, Abyss, Fallen Paradise, Released) help recovery.
• Dual Extra-Deck routes: Level 10 Sacred Beast summons and Link beatdown.

Weaknesses

• Illegal as built: 3 copies of Ash Blossom & Joyous Spring against a limit of 2.
• No side deck registered, so there is no post-side plan.
• Off-archetype tech cards (71 copies) dilute engine coherence.
• No combo, tournament or win-rate data, so the ceiling and median are inferred from text.

Critical choke points

• A Level 10 Sacred Beast must be on the field for the main win condition; removing it leaves the Link route as the only backup.
• Hand-trap density is high, so a single opposing negation of a key searcher can stall the opening.

Recommended changes

Evidence & confidence

• Verified: Main Deck is 56 cards and Extra Deck is 15, both within the TCG size rules.; Ash Blossom & Joyous Spring: 3 copies run, 2 legal (Semi-Limited), so the deck is Illegal.; Limited cards Droll & Lock Bird, Linkuriboh and S:P Little Knight are each run at 1 copy (legal).; Archetype core is 34 copies; archetype_spread shows Phantasm 25, Mulcharmy 6.
• Inferred: Going-first consistency: 3-copy starter P(>= 1 in 5) = 0.2487; archetype core P >= 0.993.; Going-second hand-trap answer P(>= 1 in 6) = 0.928.; Interaction density is high from 19 hand-trap tags and 10 negation texts.
• Provisional: Meta Power is null: no dated metagame sample.; Matchup fit and tournament reliability are unmeasured.
• 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 are absent. No win-rate telemetry (going-first/second, matchup, brick or OTK rates). Meta Power is Provisional without a dated metagame sample. No side deck registered; post-side adaptability cannot be measured.
