Master of Oz — Power Evaluation
Final Score: 27 ± 5 · Confidence: Medium
- Intrinsic: 28 · Deck: 26 · Meta: provisional
- Primary role: Boss/End-board · Secondary: Material body
Why it scores here
Master of Oz is a Level 9 Fusion Monster requiring specific materials (Big Koala + Des Kangaroo) that lack generic search engines, limiting reliable access despite appearing in 264 decks across 60 scattered archetypes. The card demonstrates no demonstrated combo conversion capability—zero combo board appearances—and provides no effect-based value; its 4200 ATK offers only passive blocking with no disruption, advantage engine, or recovery pathway. High stats alone do not drive power: the card functions as a dead-end boss body in casual/vintage-format decks where Fusion is already established, but without synergistic effects, cost-efficient access, or resilience to interruption, it converts little meaningful winning value.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 28 | Fusion Monster requiring Big Koala and Des Kangaroo, two niche materials with no generic search engine; appears at 1.42 copies per deck across 60 distinct archetypes, indicating scattered, non-core inclusion. (observed) |
| Combo & Conversion | 15 | Zero appearances in recorded combo boards despite 264 deck appearances; no text indicating combo extension or board multiplication from summoning. (verified) |
| Resource Economy | 12 | Vanilla body with no card advantage generation, search capability, or recursion; Fusion Summon itself is resource-negative requiring two specific materials and a Spell. (verified) |
| Effect & Interaction | 8 | Fusion Monster with no inherent effect text beyond materials; 4200 ATK provides only passive blocking, no negation, removal, or disruption. (verified) |
| Material Utility | 24 | Level 9 EARTH Beast Fusion that cannot typically serve as material for further summoning; generic stats offer no synergy when effect-negated or banished. (inferred) |
| Resilience & Flexibility | 18 | Single-threat Fusion Monster with no search recursion, no alternative utility across zones/turns, and no protection against removal or Fusion Summon negation. (inferred) |
| Deck-Building Efficiency | 35 | Requires specific Fusion materials limiting splash-ability; most decks run only 1 copy despite unlimited status, suggesting low confidence in access or synergy. (observed) |
Calculation
Weight profile: Primary role: Boss/End-board. Intrinsic ≈ 28, Deck ≈ 26, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- High ATK (4200) provides solid attacking power and defensive wall against low-ATK decks
- Appears in diverse archetypes (60+) suggesting broad recognition as a Fusion option
- 100% inclusion rate in Gravekeeper's archetype indicates core role in at least one established home
Weaknesses
- Vanilla Fusion Monster with no effect text—no disruption, no advantage generation, no recovery
- Requires specific Fusion materials (Big Koala + Des Kangaroo) that lack generic search, severely limiting reliable access
- Zero combo board appearances despite 264 deck appearances indicates non-synergistic, peripheral role
- Single-threat boss vulnerable to one removal spell or Fusion Summon negation with no backup
- Resource-negative Fusion Summon (−2 materials + 1 spell) with no compensating card advantage
Counters / choke points
- Ash Blossom & Joyous Spring (negates Fusion Summon)
- Mirror Force and similar board wipes (removes the monster without interaction)
- Bottomless Trap Hole (targets Fusion Monsters)
- Effect Veiler or Infinite Impermanence (blanks any effect)
Best use
Secondary or tertiary Fusion boss when materials align. Decks: Gravekeeper's. Suggested copies: 1.
Evidence & gaps
- Verified: Fusion Monster requiring Big Koala + Des Kangaroo (from card description); Appears in 264 decks across 60 distinct archetypes (from deck data); 100% inclusion in Gravekeeper's with 1 copy typical (from usage statistics); Zero combo board appearances (from combo data.appearances = 0)
- Observed: Average 1.42 copies per deck; 195 decks run 1 copy, 27 run 2, 42 run 3; Scattered across 60 archetypes with top homes: Black Luster Soldier (28), Blue-Eyes (25), Thunder Dragon (15); Top partners include banned/restricted staples (Heavy Storm, Graceful Charity, Pot of Greed), indicating vintage context; 63.3% of decks run gameplay type 7, suggesting mid-range/control homes
- Inferred: Vanilla or effect-blank Fusion Monster (materials-only description suggests no effect text); Functions as end-game boss body when Fusion materials are available; Material accessibility inconsistent—only guaranteed in Gravekeeper's, scattered elsewhere; Non-synergistic inclusion across 60 archetypes reflects broad splash potential rather than focused role
- Data gaps: No effect text provided beyond material requirement (assumed vanilla) No combo board appearances despite 264 deck appearances—combo conversion is text-only inference No guide mentions explaining role or synergy No banlist information (assumed unlimited) No demonstrated synergy mechanism for 60-archetype spread
