Ancient Gear Reactor Dragon — Power Evaluation
Final Score: 57 ± 8 · Confidence: Medium
- Intrinsic: 54 · Deck: 58 · Meta: provisional
- Primary role: Boss/End-board · Secondary: Removal
Why it scores here
The card's value comes from being a Level 9 Ancient Gear boss that is run in 400 of 400 sampled decks and is the stated finisher of the archetype (guides). Its effects add a damage-step lock on the opponent's Spell/Trap cards and monster effects while it attacks, plus an end-of-damage-step destruction of one Spell/Trap, so it converts a successful attack into removal. The 3000 ATK and 3000 DEF are not scored; the points come from the summon route, the attack-conditional interaction, and the cheap single-copy deck slot. No combo boards were supplied, so the combo and starter axes rest on text and deck data rather than observed board outcomes.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 70 | Present in 400 of 400 decks at an average of 1.1 copies, and Level 9 implies a two-Tribute Normal Summon from Ancient Gear monsters that the sample's partners support (inferred from text and deck data; no combo starter stats). |
| Combo & Conversion | 70 | The text describes a boss that converts into a lock and a removal on attack, and guides call it the archetype's repeated end-board, but no combo boards were supplied to measure what it builds from a real start (inferred). |
| Resource Economy | 30 | No card draw, search, or graveyard refuel is in the text; the destruction of one Spell/Trap is a one-for-one trade and no netCardAdvantage data was supplied (verified from text). |
| Effect & Interaction | 60 | The attack-conditional lock on the opponent's Spell/Trap cards and monster effects through the Damage Step, plus the end-of-step destruction, is strong interaction but only while it is attacking (verified from text). |
| Material Utility | 30 | Level 9 Machine with an Earth attribute is a usable material body, but no material role combo counts were supplied, and the text does not give material value once effects are negated (inferred). |
| Resilience & Flexibility | 40 | A single-zone monster whose interaction requires it to survive to attack, so one removal or negation shuts most of its value down; the sample gives no recovery route (inferred). |
| Deck-Building Efficiency | 60 | Mostly one copy per deck (370 of 400), with a fixed archetype home and no banlist token supplied, so the slot cost is low but tied to Ancient Gear shells (observed from deck data). |
Calculation
Weight profile: 0.7 Boss/End-board + 0.3 Removal/Negation. Intrinsic ≈ 54, Deck ≈ 58, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Present in 400 of 400 sampled decks, so the card is reliably live in its archetype homes
- The attack-conditional Spell/Trap and monster-effect lock plus the end-of-step Spell/Trap destruction give real interaction
- Mostly single-copy usage keeps the deck slot cost low
Weaknesses
- No combo evidence, so the observed starter, material and end-board conversion is unmeasured
- Interaction is conditional on attacking, so it does nothing if the card is removed or negated first
- Level 9 with no shown material or searcher routes gives limited material and resource value
Best use
Boss / End-board, with an attack-conditional Spell/Trap removal. Decks: Ancient Gears. Suggested copies: 1.
Evidence & gaps
- Verified: Card text: opponent's Spell/Trap cards and monster effects are locked during the Damage Step after this card attacks; Card text: end-of-Damage-Step destruction of one Spell/Trap card if this card attacked; Card text: piercing damage and the second-attack clause depend on Tribute Summoning with Ancient Gear or Gadget; Deck sample: present in 400 of 400 decks, 370 at one copy; Deck sample: 198 Ancient Gears decks and 85.2% in gameplay type 7
- Observed: Top partners: Ancient Gear Ballista in 94.5% of decks and Geartown in 93.8%; Guides name this card as the archetype's repeated boss summon
- Inferred: Level 9 implies a two-Tribute Normal Summon route (not stated in evidence); Strong deck fit with no combo evidence to confirm conversion; Deck-level resilience is limited to the Ancient Gear shell
- Data gaps: no combos supplied: combo conversion and starter/material/payoff roles are text-only inference no banlist token: assumed 3 copies (unlimited) no usage statistics (StatisticsCard): inclusion % inferred from the 400-deck sample only Tribute count for the Level 9 summon is not stated in the evidence
