Power Supplier — Power Evaluation
Final Score: 33 ± 5 · Confidence: Medium
- Intrinsic: 35 · Deck: 32 · Meta: provisional
- Primary role: Utility · Secondary: Material body
Why it scores here
Power Supplier is a niche tech option that provides modest ATK buffs to existing monsters on field, running as a singleton in Witchcrafter and Dark Magician decks. The card has zero combo synergy, generates no card advantage, and offers no opponent interaction—it is purely a self-focused stat-boost utility tool. The weak accessibility, zero combo conversion, and fragile resilience to board wipes severely limit its impact, despite the clean deckbuilding efficiency of running it as a one-off tech slot.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 35 | Level-2 Spellcaster with no searcher support; requires existing face-up monsters to function; runs as a singleton in all 14 decks, indicating flex-tech status rather than core role. (observed) |
| Combo & Conversion | 15 | Zero appearances in any recorded combo board; once-per-turn ATK buff has no chain, special summon, or GY interaction that enables extended combos. (verified) |
| Resource Economy | 25 | Generates no card advantage, no search, and no GY refuel; occupies one deck slot with only conditional ATK-boost return and no acceleration. (inferred) |
| Effect & Interaction | 10 | Purely self-focused ATK buff with zero removal, negation, hand-trap capability, or disruption of opponent plays. (verified) |
| Material Utility | 35 | Level-2 Spellcaster with 400/400 stats and no special material properties; field-locked by design and weak as fusion/synchro fodder. (inferred) |
| Resilience & Flexibility | 20 | Once-per-turn activation, requires face-up monsters to be active, dies to board wipe, offers no protection or recovery text. (inferred) |
| Deck-Building Efficiency | 55 | No garnet, no deck restriction or lock; runs as a free-roll singleton with no redundancy incentive and no archetype requirement. (observed) |
Calculation
Weight profile: Utility / no clear role (default). Intrinsic ≈ 35, Deck ≈ 32, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck (decks present, combos absent)
Strengths
- Runs cleanly as a singleton tech with no garnet or deck lock risk
- Consistent play in Witchcrafter and Dark Magician as a flex inclusion
- Generic Spellcaster—no archetype requirement or brick risk
Weaknesses
- Zero combo synergy; does not enable or extend any combo lines
- No card advantage generation, tutoring, or recursion support
- Extremely slow effect (once per turn) with minimal game-state impact
- Fragile to board wipes and disruption; offers no protection or recovery
- ATK cap (400) and field-lock requirement severely constrain utility
Counters / choke points
- Any board wipe removes both the card and its boost effect
- Opponent effects that destroy your field or negate monster effects
- Floodgates that lock your main-deck summons or hand
Best use
Flex tech for incremental ATK boost in control-focused decks. Decks: Witchcrafter, Dark Magician. Suggested copies: 1.
Evidence & gaps
- Verified: Level-2 Spellcaster, 400/400 ATK/DEF; Effect: once per turn, select a face-up monster you control; it gains 400 ATK while you control this card (400 ATK cap per monster); Runs as singleton in all 14 Witchcrafter and Dark Magician decks from April–May 2026; Zero combo appearances (0 out of any recorded boards); No removal, negation, hand-trap, or opponent-facing interaction
- Observed: 100% inclusion in 14 decks as main-deck singleton (14/14 main, 1 copy each); Appears in Witchcrafter (7 decks, 50%) and Dark Magician (7 decks, 50%); Partner cards are core archetype pieces, not combo starters or accelerators
- Inferred: Boost is continuous while Power Supplier is on field; ATK cap prevents stacking multiple boosts on one monster; Field-locked; requires face-up monster already on board to function; No built-in search or recursion; must be drawn or summoned manually; Zero-combo evidence confirms text analysis: this card does not drive combo chains
- Data gaps: No combos supplied—combo conversion is text-only inference (zero appearance confirms isolation) No guides supplied—no human strategic context on role No StatisticsCard data (usage_statistics.available: false)—inclusion % inferred from 14-deck sample only No banlist token—assumed unlimited (3 copies legal in all formats)
