Windwitch Deck #772807 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

Final Contextual Deck Power: 56/100 (±6 · Confidence: Medium)

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

Legality

Main 40 / Extra 15 / Side 0 — status: Legal.

Identity & game plan

• Win condition: Synchro beatsticks from the Extra Deck (Windwitch Diamond, Winter and Crystal Bell, plus Stardust Warrior and Accel Synchro Stardust Dragon) closing through a board established by the Bell summon engine; Damage from Winter Bell and Diamond Bell GY-target effects and Stardust negate-and-recover lines
• Turn 1 (going first): Chimes or Glass Bell search into a Bell engine (Freeze, Ice, Snow or Blizzard Bell), then a Synchro into a 2400-3000 ATK boss while holding Icy Breeze Refrain or Dominus Purge
• Turn 2 (going second): Hold Ghost Mourner, Icy Breeze Refrain and Dominus Purge for the opponent's first summon or search, then rebuild through the Bell engine from the GY
• Recovery: Glass Bell and Chimes re-search or re-summon Windwitch monsters from the Deck; Kahyoreigetsu and Fusion Parasite add board presence and Extra Deck access
• After siding: No side deck is registered, so there is no post-side plan; the deck cannot adapt between games in its submitted form

Why it scores here

The deck is scored as one system, not as an average of its cards. Thirteen starter-type main-deck cards give an estimated 0.88 chance of at least one live starter in the opening 5 (Inferred), so the engine usually comes online, although any single three-of has only about a 0.34 chance of appearing in the opening hand. Its strongest structural features are dense negate and removal text (Icy Breeze Refrain, Ghost Mourner, Dominus Purge, Stardust Dragon and Warrior, Clear Wing Synchro) and a high-ATK Extra Deck closing set, which together justify the interaction and closing scores. The median and floor are not measured because no boards were recorded, so the score rests on text and probability reads and is held back by the 0-card side deck, 28 off-archetype copies, and a Synchro sequence that is demanding to pilot. Popularity and meta-share did not earn points because no tournament data exists.

Dimension scores

How the score was computed

Strategy profile: Midrange primary with a Combo secondary; no combo evidence supplied, so profile is the Midrange default. Structural ≈ 61, Going First ≈ 62, Going Second ≈ 60, Meta = provisional, Tournament Reliability ≈ 52. Modifiers: No side deck (-3); Off-archetype dilution (-2); Engine compactness (2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional); modifiers applied after

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.88 · 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 negate and removal text across Stardust and Clear Wing Synchro monsters
• Three-of Windwitch Bell engine with multiple starters and searchers
• High-ATK Extra Deck closers at 2400 to 3000

Weaknesses

• No side deck registered
• Significant off-archetype dilution (Stardust, Dominus, Mulcharmy, Clear Wing, Parasite, Ignister, Harpie)
• No recorded boards, so the floor and median cannot be checked
• Multi-step Synchro sequencing

Critical choke points

• The Bell engine depends on Windwitch monsters on the field, so a single clean removal or negate on the first summon can stall the sequence
• Single-copy Stardust and Clear Wing Extra Deck monsters each need specific Synchro materials

Recommended changes

Evidence & confidence

• Verified: Deck is legal in OCG: 40 Main, 15 Extra, 0 Side, no banned or limited cards; Copy histogram: 12 three-of and 2 two-of; Extra Deck breakdown: 13 Synchro and 2 Fusion; Archetype purity 49.1% exact name, 28 off-archetype copies
• Inferred: Opening-hand starter probability approx 0.88 across 13 starter-type cards; Interaction density from negation and removal text; Closing power from listed ATK values and text; Pilotability from sequencing complexity
• Provisional: Meta Power is null; no dated metagame sample; Matchup fit is a neutral placeholder without tournament data
• Data gaps: No combos supplied, so 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 or second, matchup, brick or starter rates) Evidence inconsistency: usage_statistics marks Windwitch Diamond Bell, Winter Bell and Crystal Bell as not in this deck, yet cards lists each with 2 copies in the Extra Deck; the usage matching appears to skip Extra Deck cards No side deck, so post-side scores rest on composition only Deck title is null
