Steamroid — Power Evaluation
Final Score: 48 ± 8 · Confidence: Medium
- Intrinsic: 51.3 · Deck: 45.1 · Meta: provisional
- Primary role: Material body / Normal · Secondary: Utility
Why it scores here
Steamroid's text is only a Damage Step ATK swing of +500 or -500, which does not build, search, or interact with the opponent. Its value comes from being a Level 4 Earth Machine body that the Roid and Speedroid lists run as generic material, with 10 recorded decks across 6 archetypes and an average of 1.8 copies. The 1800 ATK earns no points on its own, and the lack of combo data keeps the Medium confidence band.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 40 | Live in 10 of the attached decks and co-occurs with Speedroid partners, but no starter or searched data exists to confirm a reliable route to hand (observed). |
| Combo & Conversion | 25 | No combo boards are recorded and the card text builds nothing by itself (verified from text, observed as absent from combos). |
| Resource Economy | 25 | No draw, search, or recursion; it is a plain body with no card advantage (verified from text). |
| Effect & Interaction | 5 | The only effect is a battle-step ATK modifier, so it provides no negation, removal, or hand-trap reach (verified from text). |
| Material Utility | 55 | A Level 4 Earth Machine body that stays usable as material, and the ATK swing is irrelevant to that role (inferred from text and deck usage). |
| Resilience & Flexibility | 35 | Single-body card with no redundancy or multi-zone effect; it is only as durable as the board presence it has (inferred). |
| Deck-Building Efficiency | 80 | No garnet, lock, or restriction, and 3 copies are legal in every listed format, so it is cheap to run (verified from banlist and format fields). |
Calculation
Weight profile: Pure primary role Material body / Normal, no secondary blend. Intrinsic ≈ 51.3, Deck ≈ 45.1, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Clean, generic Level 4 Earth Machine body that converts as material
- No restriction or garnet cost, so it fits any Roid or Speedroid list
- Recorded across 6 archetypes, showing it is not tied to a single home
Weaknesses
- Effect only matters during the Damage Step, so it has no board impact
- No searcher, draw, or recursion route
- Low interaction value; the body is what matters, not the text
Counters / choke points
- Standard monster removal or a negate removes the only relevant body (inferred from text)
Best use
Level 4 material body in Roid lists. Decks: Speedroid, Invoked Roids, Barbaros. Suggested copies: 2.
Evidence & gaps
- Verified: Effect is a Damage Step-only ATK change of +500 or -500 (card text); Level 4 Earth Machine, 1800 ATK / 1800 DEF, legal in TCG, OCG, MasterDuel, DuelLinks (evidence.card); Appears in 10 of 10 attached decks, with an average of 1.8 copies (decks_evidence)
- Observed: Speedroid is the largest home at 40% of decks (decks_evidence); Top partners co-occur in 5 to 7 of the 10 decks (decks_evidence); Appears in one roid-type guide section (guides_evidence)
- Inferred: Usable as a generic Level 4 material body in Roid lists despite the negated effect (text plus deck usage); Battle-step effect has little impact outside combat (text)
- Data gaps: no combos supplied, so combo conversion is text-only inference no usage statistics (StatisticsCard) available, so archetype inclusion is inferred from the 10-deck sample only no banlist token; assumed 3 copies (unlimited)
