You can only activate 1 "Oracle of Zefra" per turn.
Oracle of Zefra — Power Evaluation
Final Score: 56 ± 5 · Confidence: Medium
- Intrinsic: 52 · Deck: 58 · Meta: provisional
- Primary role: Searcher/Tutor · Secondary: Combo enabler, Resource utility
Why it scores here
Oracle of Zefra is a core search engine in Zefra decks, providing consistent access to Zefra monsters on activation and enabling a second turn of utility effects when you Ritual, Fusion, Synchro, or Xyz Summon. Its value lies in consistency and supplemental effects rather than generating card advantage or board presence; most effects are even trades (draw+discard, shuffle for removal) that support the deck's multi-summon strategy. While played at 3 copies in dedicated Zefra, its utility outside the archetype is limited, and the absence of combo evidence means combo conversion relies on text inference alone.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 72 | Runs at 3 copies in 60% of Zefra decks with multiple search partners present (Zefraath 90%, Zefraniu 84%, usage statistics 100% inclusion typical 3 copies) (verified) |
| Combo & Conversion | 32 | Conditional utility effects (shuffle removal on Ritual, special summon on Fusion, deck top manipulation on Synchro, draw cycle on Xyz) rather than guaranteed board builders, with zero combo examples supplied (inferred) |
| Resource Economy | 48 | Search effect is a 1-for-1 trade; other effects are mostly even trades or soft advantage (shuffle removal), providing resource cycling without pure card advantage generation (inferred) |
| Effect & Interaction | 24 | Only the Ritual effect provides opponent interaction as a situational shuffle removal, one of four conditional branches, with no guaranteed disruption (inferred) |
| Material Utility | 0 | Spell Card cannot be used as material for any summon method; zero utility when effect is negated (verified) |
| Resilience & Flexibility | 42 | Field Spell persists across turns but negation on activation stops the search; deck contains backup search lines (Zefra Divine Strike 80%, Providence 76%) providing resilience through redundancy (observed) |
| Deck-Building Efficiency | 68 | Efficient 3-copy inclusion in Zefra with no self-lock or garnet risk; Field Spell slot competition is manageable in the archetype (verified) |
Calculation
Weight profile: 0.7×Searcher/Tutor + 0.3×Combo enabler. Intrinsic ≈ 52, Deck ≈ 58, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck (decks present, combos absent)
Strengths
- Consistent 3-copy search engine in Zefra (100% inclusion, standardized at 3 copies in dedicated decks)
- Multiple summon types unlock diverse utility branches (Ritual removal, Fusion extension, Synchro setup, Xyz cycling)
- Core synergy with high-frequency Zefra partners (Zefraath 90%, Zefraniu 84%, Divine Strike 80%, Providence 76%)
- Searchable through established Zefra support lines (Zefraath, Zefraniu)
Weaknesses
- No guaranteed board presence or card advantage on activation (1-for-1 search only)
- Utility effects require specific Zefra summon types to unlock; effects are conditional, not guaranteed
- Vulnerable to negation on activation (hand traps like Ash Blossom stop the search)
- Limited portability outside Zefra archetype (53% core Zefra; tech pick in 47% of remaining decks)
- No opponent interaction except situational Ritual-branch shuffle removal
Counters / choke points
- Ash Blossom & Joyous Spring (negates activation)
- Called by the Grave (negates card effects)

Primary search engine and consistency tool in Zefra; tech in multi-summon archetypes. Decks: Zefra, Malefic, Symphonic Warrior, Superheavy Samurai. Suggested copies: 3.
Evidence & gaps
- Verified: Search effect on activation (text: Add 1 Zefra monster from Deck); Four conditional branches: Ritual (shuffle), Fusion (special summon), Synchro (top deck), Xyz (draw+discard); 3-copy standard in Zefra (60% of 360 decks run 3 copies); Zefra is primary home (53% of 360 decks); Spell Card has zero material utility (cannot be used as summon material); Legal in TCG, OCG, MasterDuel; limited to 1 in DuelLinks
- Observed: High deck frequency across 59 distinct archetypes; Top 5 partners are all Zefra support cards; Usage statistics show 100% inclusion in Zefra variants with 3-copy typical; Mentioned in 1 guide (Tellarknight variations)
- Inferred: Primary role is Searcher based on guaranteed activation effect; Secondary roles based on conditional summon-type triggers; Combo conversion is limited (text shows utility, not board building); Generic utility is moderate to low (archetype-focused despite 59 archetype appearances); Resilience moderate due to negation vulnerability but backup search redundancy
- Data gaps: No combo examples supplied (0 combos) — combo conversion and starter context are text-only inferences Limited guide coverage (1 guide) — broad archetype adoption inferred only from deck frequency, not guide depth No tournament ranking or metagame performance data — accessibility confidence based on deck inclusion, not competitive placing
