Penguin Sword — Power Evaluation
Final Score: 62 ± 6 · Confidence: Medium
- Intrinsic: 60 · Deck: 63 · Meta: provisional
- Primary role: Utility
Why it scores here
Penguin Sword is a support equip that runs universally in Penguin decks but lacks broader accessibility outside its archetype. Its effects—+800 ATK boost, conditional bounce on battle damage, and negation of returned cards—reliably support Penguin's bounce-focused game plan, earning a moderate score for a specialized support card. The lack of combo data and guide evidence limits confidence, and the card's effectiveness depends entirely on having a Penguin monster on field.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 75 | Runs in 100% of Penguin decks with universal inclusion and multiple copies, though it requires a Penguin monster in play to equip to. (verified) |
| Combo & Conversion | 67 | Supports Penguin's bounce engine with +800 ATK boost and conditional bounce/negation effects, but both require battle damage or Penguin bounces to fully convert. (inferred) |
| Resource Economy | 60 | Provides potential card advantage through bounce on battle damage and negation of specific cards, though both effects are conditional on opponents' actions. (inferred) |
| Effect & Interaction | 70 | Negation effect on cards returned to hand/banished by Penguin effects is strong disruption, though it requires specific triggering conditions to activate. (verified) |
| Material Utility | 5 | As a Spell card equip with no summon/material synergy, contributes minimal material utility beyond its role as equip. (verified) |
| Resilience & Flexibility | 45 | Fragile when the equipped monster is destroyed or removed, with no recovery mechanism and no protection across interruptions. (inferred) |
| Deck-Building Efficiency | 72 | Archetype-locked to Penguin monsters only, but runs smoothly in its home archetype with consistent 1-3 copy inclusion across 64 decks. (observed) |
Calculation
Weight profile: Primary: Utility (no clear role default). Intrinsic ≈ 60, Deck ≈ 63, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Universal inclusion in pure Penguin decks (100% of Penguin sample)
- Multiple copies frequently run (15 of 64 decks run 3 copies)
- Provides both offensive boost (+800 ATK) and defensive negation
- Synergizes cleanly with all core Penguin archetype cards
- Bounce effect enables card advantage when battle damage connects
Weaknesses
- Archetype-locked: only equips to Penguin monsters
- Requires a monster in play to function
- Fragile to monster removal or bounce effects
- All effects are conditional rather than guaranteed
- No material or graveyard utility if destroyed
Counters / choke points
- Monster removal or bounce disrupts the equip
- Negation of the equipped monster prevents effects
- Cards unaffected by effect negation bypass the negation component
Best use
Equip support providing ATK boost, bounce, and conditional negation. Decks: Penguin (primary), Adamancipator (secondary splash), Icejade (secondary splash).
Evidence & gaps
- Verified: Equip-only restriction: 'Equip only to a Penguin monster'; ATK boost: Gives +800 ATK to equipped monster; Bounce trigger: Returns 1 opponent card to hand on battle damage; Negation effect: Negates effects of cards returned by Penguin effects until end of next turn; Once-per-turn clause on negation effect; 100% of pure Penguin decks (40/40) run at least 1 copy; 15 of 64 decks (23.4%) run 3 copies; All top 10 partners are Penguin archetype cards
- Observed: Appears in 64 total decks across 13 distinct archetypes; Average 1.56 copies per deck (range 1-3); 62.5% of sample is pure Penguin, with smaller presence in Adamancipator (10.9%) and Icejade (9.4%); Primarily in Pendulum Synchro gameplay (93.8% of decks)
- Inferred: Accessibility is high in Penguin decks due to 100% inclusion and multiple searcher partners (Penguin Soldier, Great Emperor Penguin, etc.); Combo conversion likely supported by Penguin's established bounce mechanics, though no combo data confirms this; Bounce and negation effects support Penguin's control-focused strategy; Resilience is limited due to equip-to-monster dependency and no self-recovery
- Data gaps: No combos supplied — combo conversion is text-only inference from Penguin bounce mechanics No guides supplied — no expert commentary on card role and applications No banlist token — assumed 3 copies legal (unlimited) No usage statistics (StatisticsCard) — archetype inclusion % inferred from 64-deck sample only
