Blade Armor Ninja — Power Evaluation
Final Score: 45 ± 8 · Confidence: Medium
- Intrinsic: 41 · Deck: 48 · Meta: provisional
- Primary role: Extender · Secondary: Board breaker
Why it scores here
Blade Armor Ninja is a Rank 4 Xyz whose only effect is a once-per-turn detach that gives one targeted Ninja monster a second attack each Battle Phase. It earns its score from reliable access (it appears in all 400 sampled decks, usually as a single copy) and cheap deck cost, not from its 2200 ATK, which earns nothing. Its conversion is limited: it adds pressure on a board that already exists, costs a material, provides no card advantage or interaction, and only works on Ninja monsters, so its value depends on a Ninja shell being in place.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 60 | Present in 400 of 400 sampled decks at 1.13 average copies, but no combo evidence exists to confirm starter or search routes (observed deck inclusion, inferred Level 4 Warrior summon route). |
| Combo & Conversion | 35 | The text only adds a second attack to one targeted Ninja and no recorded boards exist to confirm a larger conversion (verified text, inferred impact). |
| Resource Economy | 25 | Detaching a material is a cost with no refuel, search, or card gain stated in the text (verified text). |
| Effect & Interaction | 10 | The effect contains no negation, removal, or hand-trap function (verified text). |
| Material Utility | 20 | As a Xyz monster it is not a generic material body and is limited to Xyz use at Rank 4 (inferred from frame and text). |
| Resilience & Flexibility | 30 | Its single effect is easily stopped by one negate, and it needs a material and a Ninja target each turn (inferred from text). |
| Deck-Building Efficiency | 60 | Typically a one-copy slot with no garnet or lock restriction in the 400-deck sample (observed deck copies, inferred slot cost). |
Calculation
Weight profile: 0.7 Extender + 0.3 Board breaker. Intrinsic ≈ 41, Deck ≈ 48, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Live in 400 of 400 sampled decks, so it is reliably accessible in its archetype homes
- Cheap, one-copy slot that can be run without deckbuilding cost
- Second attack on a targeted Ninja adds pressure to an existing board
Weaknesses
- Only targets Ninja monsters, which limits its use outside Ninja shells
- Costs a material per use with no card advantage or refuel
- No negation, removal, or interaction function
- One negate on the effect ends its value
Counters / choke points
- Negation of the Xyz monster's effect
- Board-wipe or mass-removal effects that clear the Ninja board before the Battle Phase
- Interruption of the Battle Phase or the attack declaration
Best use
Extra attack finisher in Ninja shells. Decks: Ninja, Borrel, Ninjitsu Art. Suggested copies: 1.
Evidence & gaps
- Verified: Xyz summon from two Level 4 Warrior monsters (card text); Once-per-turn detach of one material to give a Ninja monster a second attack each Battle Phase (card text); Present in 400 of 400 sampled decks with 1.13 average copies (deck evidence)
- Observed: Top partners co-occur in 87 to 94 percent of decks (deck evidence); Ninja archetype accounts for 48.2 percent of decks and Ninja-named variants for 21.5 percent (deck evidence)
- Inferred: Second attack is a finisher and pressure tool, not a board-breaking interaction (inference from text); Accessibility depends on having two Level 4 Warriors available (inference from text and Xyz rules)
- Data gaps: no combos supplied, so combo conversion is text-only inference no banlist token, assumed 3 copies (unlimited) no usage statistics (StatisticsCard), so archetype inclusion is inferred from the 400-deck sample only no average starter count, so deck resilience is estimated from archetype spread
