Leeching the Light — Power Evaluation
Final Score: 46 ± 6 · Confidence: Medium
- Intrinsic: 44 · Deck: 48 · Meta: provisional
- Primary role: Utility · Secondary: Board breaker
Why it scores here
Leeching the Light is a one-shot Normal Spell that converts a board of face-up Attack Position monsters into extra ATK for one turn, by copying the ATK of one opposing LIGHT monster. It has no searcher, refuel, negation, or body of its own, so it scores in the middle-low range on a Utility profile. Its 40-deck presence across 18 archetypes confirms it is a playable, portable staple (accessibility and deckbuilding are strong), but that frequency is not treated as proof of power. The 1,800-point-style ATK on paper earns nothing here; the score rests on the text and on the absence of any observed combo conversion.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 55 | Present in 40 of 40 sampled decks at 2.45 copies average across 18 archetypes, but it is a Spell with no searcher or refuel route in the evidence (observed). |
| Combo & Conversion | 35 | Text only: the effect converts existing Attack Position monsters into damage, but there are zero recorded combo boards to confirm a conversion chain (inferred). |
| Resource Economy | 20 | A single card for a one-shot ATK buff with no draw, search, or recursion; it is a 1-for-0 play (verified). |
| Effect & Interaction | 10 | Selects an opposing LIGHT monster for its ATK value only; it does not negate, destroy, or remove anything (verified). |
| Material Utility | 10 | A Spell card cannot be used as Xyz, Synchro, Fusion, or Link material, so it contributes no body value (verified). |
| Resilience & Flexibility | 40 | Single copy of an effect with no protection, redundancy, or recovery; an opponent's response or a Spell-negating card ends it (inferred). |
| Deck-Building Efficiency | 70 | Zero cost, no garnet or lock restriction, and copies stack without downside across a wide archetype spread (observed). |
Calculation
Weight profile: Utility default profile (no clear primary role); no secondary blend applied. Intrinsic ≈ 44, Deck ≈ 48, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Zero-cost Spell playable in most decks with no garnet or restriction
- Portable across 18 archetypes in the sample
- Turns existing Attack Position boards into extra damage in one turn
Weaknesses
- No card advantage, search, or recursion
- Only a one-turn ATK boost; no removal or negation
- Depends on an opposing LIGHT monster being present to select
Counters / choke points
- Spell-negation or Spell-response cards
- Removing or switching the targeted LIGHT monster is not the counter; the buff is applied on resolution
- Boards with no Attack Position monsters of the user's own
Best use
Utility ATK-boost finisher for Attack Position boards. Decks: Secret Six Samurai, Naturia, Ice Barrier, Kaiju, Numeron, Cyber Dragon. Suggested copies: 2.
Evidence & gaps
- Verified: Text: select 1 face-up opposing LIGHT monster; your Attack Position monsters gain its ATK until End Phase; Spell card: cannot be material; no cost or once-per-turn clause in text; Present in 40 of 40 sampled decks
- Observed: Average 2.45 copies per deck across 18 archetypes; Co-occurs with Jizukiru, Thunder King, and Dimensional Fissure in 50%+ of sampled decks
- Inferred: Functions as a finisher or pressure spell rather than a board-control card; Resilience is low because one response ends it
- Data gaps: no combos supplied — combo conversion is text-only inference no guides supplied no banlist token — assumed 3 copies (unlimited) no usage statistics (StatisticsCard) — archetype inclusion % inferred from deck sample only
