Mist Valley Deck #768028 — Yu-Gi-Oh! OCG

Deck — Deck Power Evaluation

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

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

Legality

Main 40 / Extra 15 / Side 0 — status under the rules at evaluation time: Illegal. 1 violation(s).

Identity & game plan

• Win condition: Tribute-summon and Normal-summon chains of Floowandereeze monsters into high-ATK Winged Beast boss monsters (Floowandereeze & Snowl, Raiza, Simorgh-Raidraptor lines); Xyz and Link pressure from Raidraptor - Ultimate Falcon, Superdreadnought Gustav Max and Knightmare boards
• Turn 1 (going first): Open a Floowandereeze starter (Robina, Eglen, Stri, Toccan) and use the Magnificent Map or Advent of Adventure to search a second Floowandereeze, then Tribute or Normal summon into the Extra Deck boss
• Turn 2 (going second): Use Ghost Ogre, Ghost Belle, Droll & Lock Bird and Effect Veiler as hand traps to slow the opponent's first summon, then play the Floowandereeze engine on the next turn
• Recovery: Searchers (Magnificent Map, Advent of Adventure, Dreaming Town, Pot of Duality) refill the hand from the Main Deck; banished Floowandereeze cards can be recycled through Toccan's effect
• After siding: Not evaluable: the Side Deck is empty (0 cards), so there is no post-side plan

Why it scores here

The score is capped at 30 because the list is Illegal: three copies of Pot of Extravagance exceed the OCG Semi-Limited limit of two, so the structural result (about 49) is shown for reference only and is not a normal Final Contextual score. The structural read is driven by engine density, not by averaging card scores. The deck runs 19 searcher-text cards, so the Floowandereeze core is about 99.9% likely to appear somewhere in the opening hand (Inferred), but any single 3-copy starter is only about 34% likely in a 5-card going-first hand (Inferred). Eight hand traps give a 76% chance of at least one going-second, which supports interaction (Inferred). The deck has no recorded boards, no tournament link and no side deck, so floor, median and ceiling output cannot be measured and are scored at neutral or low values. Archetype popularity was not credited; the Extra Deck breadth (8 Xyz, 5 Link, 2 Fusion) is the strongest structural feature. Fixing the copy limit would likely lift the score into the 45-50 range, but that is a projection, not a measured result.

Dimension scores

How the score was computed

Strategy profile: Midrange. Structural ≈ 49.7, Going First ≈ 48, Going Second ≈ 50, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: Illegal legality cap (-19). Final formula: Illegal cap: uncapped 0.80*Structural(49.7) + 0.20*TournamentReliability(45) = 48.8, capped to 30 (theoretical/structural-only); Meta Power provisional

Probability & combo summary

• Opening a starter: P(≥1) ≈ 0.34 · 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 Floowandereeze engine with 19 searcher-text cards and a 99.9% core archetype presence
• Eight hand traps and six negation effects give layered going-second interaction
• Full Extra Deck (8 Xyz, 5 Link, 2 Fusion) with multiple boss options

Weaknesses

• Illegal: Pot of Extravagance is over the OCG copy limit
• No side deck, so no post-side plan
• No recorded combos or tournament data to validate the ceiling
• Low single-starter odds in the opening hand (about 34% for a 3-copy starter)

Critical choke points

• Any single 3-copy starter is only about 34% likely in a 5-card going-first hand
• Tribute-summon routes depend on the Floowandereeze chain staying intact

Recommended changes

Evidence & confidence

• Verified: Legality: 40 main, 15 extra, 0 side; Pot of Extravagance over copy limit (3 run, 2 allowed); Card text and types for all 39 distinct cards; Extra Deck breakdown: 8 Xyz, 5 Link, 2 Fusion
• Inferred: Starter probabilities (hypergeometric) and hand-trap odds; Engine consistency and brick-rate estimates; Interaction density read from text
• Provisional: Meta Power and matchup fit (no dated metagame sample supplied)
• Data gaps: No combos supplied, so floor, median and ceiling output are text-only inference No tournament link, so archetype meta-share and per-pilot record are absent No win-rate telemetry exists in YGOVN Meta Power is Provisional unless a dated metagame sample is supplied Side Deck is empty, so post-side performance cannot be assessed
