Deck — Deck Power Evaluation

Final Contextual Deck Power: 59/100 (±8 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Midrange
• Format: tcg

Legality

Main 43 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Summon Level 10 Sacred Beast boss monsters (Raviel, Hamon, Gustav Rocket, Galaxy Destroyer) from Extra Deck and attack for 4000-5000 ATK; Gustav Max direct damage and Dark World / Train Extra Deck boards
• Turn 1 (going first): Open Sacred Beast starter (Summoner, Martyr, Mulcharmy or Card of the Soul) to add a Level 10 Sacred Beast, Special Summon it with a Sacred Beast card, then Xyz or Fusion into a boss; hold Ash Blossom or Ghost Ogre for the key response
• Turn 2 (going second): Use the 5 hand traps (Ash Blossom, Ghost Ogre, Droll & Lock Bird) to blank opposing lines, then rebuild a Sacred Beast board from the GY through Released and Martyr
• Recovery: Recycle Sacred Beasts Released and Martyr from the GY, and use Card of the Soul and Mulcharmy Fuwalos draws to reload the hand after a board wipe (Inferred)
• After siding: No side deck is registered, so there is no post-side plan; the deck cannot adapt between games of a best-of-3

Why it scores here

The deck reliably opens a functional plan: 26 archetype-core copies give a roughly 99% chance of at least one core card in a 5-card opening hand and 24 searcher-text cards give about 99% searcher access (Inferred). Its ceiling comes from Level 10 Sacred Beast bosses such as Raviel, Hamon and Gustav Rocket, which reach 4000-5000 ATK, with a second route through Gustav Max direct damage. Conversion is held back by the absence of recorded boards, so the combo ceiling and floor are text-only inference and the median is unknown. Interruption resilience is the strongest structural feature, with 5 hand traps, Buio, Skyfall, Combined Assault and multiple recursion routes that let the engine continue after a single answer. The score is not earned by the deck's popularity (no tournament share is available), and it does not average the individual card scores. Its main drag is the lack of any side deck and the Limited-status Gustav Max and Droll & Lock Bird, which leave no post-side plan and little margin on banlist-sensitive copies.

Dimension scores

How the score was computed

Strategy profile: Combo. Structural ≈ 64.5, Going First ≈ 66, Going Second ≈ 56, Meta = provisional, Tournament Reliability ≈ 62. Modifiers: unrecoverable Sacred Beast gate (-2); no side deck (-2); banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional): 0.80*64.5 + 0.20*62 = 64.0, then -5 modifiers = 59

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.99 · key two-card combo ≈ — · full-brick estimate ≈ 0.01 (all Inferred)
• Combo output: best PowerIndex —, median —, board-per-starter —
• Turn order: 0 going-first lines vs 0 going-second lines

Strengths

• Dense archetype core (26 copies) gives near-certain starter access
• Five hand traps plus layered negation and removal (Skyfall, Illusion Gate, Combined Assault)
• Strong Level 10 boss ceiling (Raviel, Hamon, Gustav Rocket, Galaxy Destroyer)
• Recursion through Released and Martyr supports interruption recovery

Weaknesses

• No side deck, so no post-side adaptability
• Engine conflicts between the Phantasm core and generic staples (58 off-archetype copies)
• No recorded boards, so combo floor and median cannot be measured
• Core Extra-Deck cards from the usage stats (Chaotic Phantasmal, Thunder Dragon Colossus, Little Knight) are absent

Critical choke points

• A Sacred Beast must be on the field before Level 10 boss summons; clearing the first Sacred Beast removes the boss route (Inferred)
• Gustav Max and Droll & Lock Bird are Limited, so any copy loss affects the lock and pressure lines
