Rose Dragon Deck #771513 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 30/100 (±8 · Confidence: Medium)

• Primary strategy: Combo
• Secondary strategies: Toolbox, Control
• Format: ocg

Legality

Main 56 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 4 violation(s).

Identity & game plan

• Win condition: Synchro and Fusion boss monsters from the Ashtra and Azamina sub-engines (Ashtraja Susanoo, Ashtraya Mikumari-no-Mikoto, Akasuna-line Ashtra monsters) that attack through a board cleared by Synchro and Trap removal; Azamina Fusion monsters and Dark Magician of Destruction as recursion-based follow-up pressure
• Turn 1 (going first): Open Yoa or Mikumari with a face-down Set card, return it to the hand or Extra Deck to Special Summon, and use Ashtra Web or Ashtra Domain to reach a Synchro boss; the 4 Forbidden cards are not in the legal list, so this plan is theoretical only
• Turn 2 (going second): Hold Ash Blossom, Dominus Impulse, Solemn Warning, Ghost Ogre and Infinite Impermanence to answer the opponent's first summon or activation, then convert the surviving board into an Ashtra Synchro
• Recovery: Ashtra monsters and traps in the GY or banishment can be added back to hand or Set by Ashtraja Susanoo and Ashtraya Mikumari, so the engine can rebuild after a single disruption
• After siding: No side deck is registered (side count 0), so there is no post-side plan; side-deck adaptability is scored as a structural gap

Why it scores here

The list is illegal in OCG: four Forbidden cards (Original Sinful Spoils - Snake-Eye, Red-Eyes Dark Dragoon, Azamina Ilia Silvia, Baronne de Fleur) are run at one copy each, so this is a theoretical, structural-only read capped at 30. The deck opens its engine through Ashtra summon-by-reveal monsters, Ashtra traps, and Azamina/Diabellstar searchers, with a 0.85 chance of at least one searcher in a 5-card opening hand (Inferred). Interaction is the deck's strongest area, with 9 hand traps, 20 negation-text cards and 17 removal-text cards giving broad answers to a single opposing play. The deck is not an archetype build: none of the 5 usage-stat core Rose Dragon cards are present, and exact-name archetype purity is 0%, so the score comes from the system's consistency, interaction, and Synchro/Fusion boss output, not from the popularity of the Rose Dragon label or from averaging card scores. Recorded combo data is absent, so floor, median and ceiling are text-only inferences and stay low-confidence.

Dimension scores

How the score was computed

Strategy profile: Combo primary, Toolbox secondary (approximately 80:20, weights not separately adjusted). Structural ≈ 54, Going First ≈ 55, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist exposure (-12); dependence on one Extra-Deck card (0); Illegal list cap (0). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional) = 52.4 before modifiers, then capped at 30 because the deck is Illegal (four Forbidden cards at one copy each); theoretical/structural-only

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

• Nine hand traps and about 20 negation-text cards give several answers to a first play
• Ashtra revival monsters, searchers and Ashtra Web/Domain give two or more restart routes
• Synchro and Fusion bosses reach 3000+ ATK for closing pressure

Weaknesses

• Four Forbidden cards make the list illegal in OCG
• The deck does not run the Rose Dragon archetype's core cards, so the archetype label is inaccurate
• No side deck, so there is no post-side plan
• No combo evidence, so median output is unknown

Critical choke points

• Single-copy Forbidden cards must be removed before the list is playable
• The Ashtra revival line depends on a face-down card being present, so an early Set-card removal stops it

Recommended changes

Evidence & confidence

• Verified: Illegal status: four Forbidden cards at one copy each (legality.violations); 56 Main, 15 Extra, 0 Side; Main and Extra sizes are within the OCG limits; Archetype purity 0%; 71 off-archetype copies; 0 of 5 usage core cards present
• Inferred: P(>=1 starter in 5) = 0.249 for 3-copy starters; searcher group 0.849; Hand-trap group P(>=1 in going-second 6) = 0.669; Interaction density from negation and removal text is high; Ashtra engine restart routes from card text
• Provisional: Meta Power is null; no dated metagame sample; Matchup coverage 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 records are absent No win-rate telemetry; going-first/second, matchup and brick rates are Inferred or Unknown Meta Power is Provisional without a dated metagame sample Deck title is null; archetype label Rose Dragon does not match the card list
