Blue Mountain Butterspy — Power Evaluation
Final Score: 48 ± 8 · Confidence: Medium
- Intrinsic: 47.7 · Deck: 48.1 · Meta: provisional
- Primary role: Extender · Secondary: Material body
Why it scores here
Blue Mountain Butterspy scores on access and body, not on what it does. Its only route is a hand Special Summon after a Warrior is Normal Summoned, so it converts into a 0 ATK / 1700 DEF Level 4 body and nothing more. Running in 134 decks across 33 archetypes confirms it is a live, portable slot, but that is frequency rather than strength, so it does not lift the score much. Its 0 ATK earns nothing, and with no combo evidence and no resource or interaction value it stays near the middle.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 45 | Needs another Warrior Normal Summon to trigger the hand Special Summon, and the card cannot be Normal Summoned or Set itself; live in 134 decks but no combo starts recorded (verified text, observed decks). |
| Combo & Conversion | 35 | Text gives a single body from a Warrior Normal Summon; no recorded boards or payoff examples (verified text, inferred conversion). |
| Resource Economy | 15 | No draw, search, banish, or recursion on the card; it is a body with no advantage gain (verified text). |
| Effect & Interaction | 5 | No negation, removal, or hand-trap effect in the text (verified text). |
| Material Utility | 50 | Level 4 DARK Warrior body usable as generic material, but cannot be Synchro material (verified text, inferred Xyz/Link/Fusion use). |
| Resilience & Flexibility | 40 | One trigger route through a Warrior Normal Summon, so one interruption ends it; spread across 33 archetypes gives some portability (verified text, observed decks). |
| Deck-Building Efficiency | 75 | Typical 1 copy with no garnet or lock restriction; the hand Special Summon costs no slot beyond the card itself (observed usage, verified text). |
Calculation
Weight profile: Extender primary; no secondary blend. Intrinsic ≈ 47.7, Deck ≈ 48.1, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Hand-to-field body triggered by any Warrior Normal Summon, so it extends a Warrior line without a search
- Level 4 DARK Warrior body usable as generic Xyz/Link/Fusion material
- Played in 134 recent decks across 33 archetypes at about 1.74 copies, a live and portable slot
Weaknesses
- Cannot be Normal Summoned or Set, so it needs a separate Warrior Normal Summon every time
- Cannot be used as Synchro material
- 0 ATK / 1700 DEF with no effect beyond the summon, so no resource or interaction value
- No combo evidence: zero recorded boards
Counters / choke points
- Interruption of the triggering Warrior Normal Summon (inferred from the trigger text)
- Negation of the hand Special Summon once it is triggered (inferred from the trigger text)
Best use
Warrior-line extender and material body. Decks: Phantom Knights, Elemental Hero, Bamboo Sword, Heroic, Battlin' Boxer. Suggested copies: 1.
Evidence & gaps
- Verified: Card text: cannot be Normal Summoned or Set; hand Special Summon when you Normal Summon a Warrior; cannot be Synchro material; Level 4 DARK Warrior, 0 ATK / 1700 DEF; 134 recent decks, 33 distinct archetypes, average 1.74 copies per deck
- Observed: 73.1% of decks are in gameplay type 4; Usage statistics show 100% inclusion in Genex and Elemental Hero and 85.7% in Bamboo Sword, all at 1 typical copy; Top partners appear in 59–81% of decks; zero combo boards recorded
- Inferred: The card is a Warrior-line extender whose value depends on a separate Warrior Normal Summon; Xyz/Link/Fusion material use follows from the Level and attribute, since the text places no material restriction beyond Synchro
- Data gaps: no combos supplied — combo conversion is text-only inference no banlist token — assumed 3 copies (unlimited) no rulings or FAQ supplied for the hand Special Summon timing the single guide snippet is an archetype overview with no card-specific analysis
