Sacred Beast Deck #771567 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 38/100 (±6 · Confidence: Medium)

• Primary strategy: Midrange
• Secondary strategies: Toolbox
• Format: ocg

Legality

Main 46 / Extra 1 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Level 10 boss monsters (Uria, Hamon, Raviel, 4000 ATK each) special-summoned through their own conditions, with Armityle the Chaos Phantasm (10000 ATK on your turn) as the single Extra Deck closer; Dark Summoning Beast and Fusion Draft as searchers and alternate routes to a boss
• Turn 1 (going first): Open on Break the Seal, Fallen Paradise, or a searcher to set up Trap or Continuous Spell fuel for a boss, while holding Ash Blossom and Ghost Ogre for the opponent's first play
• Turn 2 (going second): Use Ash Blossom, Ghost Ogre, Droll and Ghost Mourner to strip the opponent's first engine piece, then rebuild a boss from the graveyard or deck
• Recovery: Break the Seal and Umbral Horror Unform/Will o' the Wisp recycle cards and create bodies; Fusion Draft and the searchers rebuild the hand
• After siding: No side deck is registered, so there is no post-side plan in the evidence

Why it scores here

The deck is scored as a Midrange system: the three Level 10 Sacred Beast bosses each need a separate summon condition (3 face-up Traps, 3 Continuous Spells, or 3 Fiends), so the engine is only live in roughly half of opening hands (P of at least one of the six bosses in a 5-card hand is about 0.52, Inferred). Interaction is the strongest part of the system, with four hand traps and several Quick-Effect negations, which keeps the deck playable on either turn order. The Extra Deck holds one card, Armityle, which needs all three bosses on the field, so the closing plan rests on a single Extra card. The archetype is only partly represented (11 of 46 Main Deck cards are exact-name Sacred Beast; 36 are off-archetype, including Umbral Horror, Trap Monster, Royal and Chaos Phantom), and 13 of the 14 archetype-standard core cards are absent. Popularity and the archetype label did not earn points, and the score comes from the system as a whole, not from an average of the individual card scores.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 46, Going First ≈ 42, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 38. Modifiers: Single Extra Deck dependence (-3); Engine conflicts (-2); Banlist exposure (-1). Final formula: 0.80*Structural + 0.20*TournamentReliability + ContextModifiers (Meta provisional): 0.80*46 + 0.20*38 - 6 = 38.4 → 38

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.52 · 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

• Four hand traps (Ash Blossom, Ghost Ogre, Droll & Lock Bird, Ghost Mourner) give interaction on both turn orders
• Several boss monsters at 4000 ATK plus a 10000-ATK Extra closer give a high ceiling once the engine is live
• Break the Seal and Umbral Horror recursion give resource recovery

Weaknesses

• Each boss needs a different fuel (3 Traps, 3 Continuous Spells, or 3 Fiends), so the engine is live in only about half of opening hands
• Only 23.4 percent exact-archetype purity and 13 of 14 archetype-standard core cards missing
• Single Extra Deck card with no backup closer
• No side deck, so no post-side adaptation
• Dead or low-impact singletons such as Infinite Cards and Zerozerock

Critical choke points

• Armityle requires Uria, Hamon and Raviel all on the field at once, so losing one boss stops the Extra Deck plan
• The Trap and Continuous Spell fuel for the bosses depends on a small number of Break the Seal and Trap cards

Recommended changes

Evidence & confidence

• Verified: Deck is legal in OCG with 46 Main, 1 Extra, 0 Side and five Limited cards at one copy each; Archetype usage stats list 13 core cards missing from this deck; Exact-name purity is 23.4 percent (11 of 47 copies)
• Observed: Only one Extra Deck card (Armityle); Side deck is empty
• Inferred: Boss engine is live in about 52 percent of 5-card opening hands; Hand traps provide layered interaction on both turn orders; Going-first and going-second estimates
• Provisional: Meta Power and the matchup reading, since no dated metagame sample or tournament link is available
• Data gaps: No combos supplied, so combo floor, median and ceiling are text-only inference No tournament link, so archetype meta-share and per-pilot records are absent No win-rate telemetry No dated metagame sample, so Meta Power is provisional Side deck is empty, so post-side performance cannot be assessed
