Lightning Blade — Power Evaluation
Final Score: 47 ± 8 · Confidence: Medium
- Intrinsic: 46 · Deck: 47 · Meta: provisional
- Primary role: Utility · Secondary: Board breaker
Why it scores here
Lightning Blade is a one-copy Warrior-only Equip Spell: it adds 800 ATK to a Warrior-type monster and gives all WATER monsters -500 ATK. Its score comes from a clean, cheap, low-restriction body that is played in 13 sampled decks across 9 archetypes, not from its ATK gain or its debuff. It does not convert a card into board or advantage on its own, and it depends on a live Warrior, so the score stays in the middle band. High-stat outcomes earn nothing here; the score reflects only how reliably a Warrior-side equip turns into value.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 45 | Needs a live Warrior-type monster on the field before it can equip; no searcher or recursion in the evidence, so access depends on the hand and board (inferred). |
| Combo & Conversion | 40 | Only converts a Warrior already on board into +800 ATK; no recorded combo boards exist, so conversion is text-only inference. |
| Resource Economy | 25 | A single -1 card that gives no card advantage and no refuel; it only adds stats while equipped (verified). |
| Effect & Interaction | 35 | The WATER -500 ATK clause is soft, situational interaction with no negation or removal (verified). |
| Material Utility | 15 | An Equip Spell cannot be used as material, so the material axis is near zero (verified). |
| Resilience & Flexibility | 35 | Falls off when the equipped Warrior leaves the field and needs a Warrior target every time (inferred). |
| Deck-Building Efficiency | 75 | Runs at 1 copy in 10 of 13 decks (avg 1.46 copies), with no garnet or self-lock clause (observed, verified). |
Calculation
Weight profile: Utility / no clear role (default); Board breaker considered as secondary but not blended. Intrinsic ≈ 46, Deck ≈ 47, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- +800 ATK to a Warrior-type monster (verified from text)
- Cheap single-copy slot with no garnet or lock clause (verified from text, observed in decks)
- Appears across 9 archetypes and 5 gameplay types, so it is not tied to one home (observed)
- Co-plays with Monster Reborn in 46% of sampled decks (observed)
Weaknesses
- Equip target is restricted to Warrior-type monsters (verified from text)
- Stat gain is lost when the equipped monster leaves the field (inferred)
- WATER debuff is situational and does not affect non-WATER boards (verified from text)
- No recorded combo or guide evidence of its real impact (data gap)
Counters / choke points
- Removal or banishing of the equipped Warrior, which strips the equip (inferred)
Best use
Utility ATK boost; situational WATER debuff. Decks: Warrior-based decks running a single copy, Decks that already run Monster Reborn or Gilford the Lightning. Suggested copies: 1.
Evidence & gaps
- Verified: Equip only to a Warrior-Type monster; gains 800 ATK (card text); All WATER monsters lose 500 ATK (card text); Equip Spell, no material use (card type)
- Observed: 13 sampled decks, 9 distinct archetypes, avg 1.46 copies per deck (decks_evidence); Monster Reborn co-occurs in 6 of 13 decks (decks_evidence)
- Inferred: Access depends on having a Warrior on board and in hand (no searcher evidence); Equip is lost when the monster leaves the field
- Data gaps: no combos supplied — combo conversion is text-only inference no guides supplied no usage statistics (StatisticsCard) — archetype inclusion % inferred from deck sample only no banlist token — assumed 3 copies (unlimited)
