Equip only to a Machine-Type monster. Once per turn: You can activate this effect; it permanently gains 400 ATK. (This ATK gain remains even if this card leaves the field or the monster becomes unaffected by card effects.) If it battles an opponent's monster, that monster's effect is negated during the Battle Phase only.
Gravity Blaster — Power Evaluation
Final Score: 45 ± 6 · Confidence: Medium

- Primary role: Utility · Secondary: Board breaker
Why it scores here
Gravity Blaster is a one-copy-style Machine-support Equip Spell: its value is a once-per-turn +400 ATK on the equipped monster and a Battle Phase negation of the monster it battles. It is played in 15 of 15 sampled decks across 11 archetypes, which confirms it is a practical, portable card, but that frequency is not credited as power. Because it is a Spell, it cannot be material, and it has no combo, searcher or card-advantage evidence, so those axes score low; its 400 ATK is a modest, once-per-turn gain, not a board-maker.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 55 | Appears in 15 of 15 sampled decks at about 1.33 copies, but there is no searcher or starter evidence and it needs a Machine on the field (text plus deck stats; observed/inferred). |
| Combo & Conversion | 30 | No combo boards recorded; the only verified conversion is +400 ATK once per turn on the equipped monster (text; verified). |
| Resource Economy | 25 | A spell spent for a stat gain with no draw, search or recursion in the text; the ATK gain persists after it leaves the field, a small positive (text; verified). |
| Effect & Interaction | 40 | Negates the effect of a monster it battles, but only during the Battle Phase and only on attack (text; verified, strength inferred as soft). |
| Material Utility | 5 | A Spell Card cannot be used as Xyz/Link/Fusion/Synchro material, so the body contributes nothing here (text; verified). |
| Resilience & Flexibility | 45 | The ATK gain survives the card leaving the field, but the Equip itself is removable by generic Spell removal and is limited to Machine targets (text; inferred). |
| Deck-Building Efficiency | 60 | Single-copy-friendly Spell with no garnet or lock; the Machine-only restriction limits where it is castable (text plus deck copies; observed/inferred). |
Calculation
Weight profile: 0.7 Utility + 0.3 Board breaker. Intrinsic ≈ 44.2, Deck ≈ 44.8, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Cheap, permanent +400 ATK once per turn on a Machine
- Battle Phase negation of the monster it attacks or is attacked by, which is hard to hit cleanly
- Portable: played across 11 archetypes with the Machine restriction as its only gate
Weaknesses
- Low ceiling: +400 ATK once per turn does not build a board or change the game alone
- Spell card, so it cannot be material and contributes no Link/Xyz/Synchro/Fusion body
- Negation is limited to the Battle Phase and to the monster it battles
- No combo, searcher or card-advantage evidence in the pack
Counters / choke points
- Generic Spell removal or Equip destruction (inferred from card type)
- Opponent Machine-type restrictions or boards without Machine targets (inferred)
Best use
Machine-support Equip for attack pressure and Battle Phase negation. Decks: Cyber Dragon, Mikanko, Ancient Gears, Morphtronic. Suggested copies: 1.
Evidence & gaps
- Verified: Card text: Equip only to a Machine-Type monster; once per turn +400 ATK that persists after leaving the field; Battle Phase-only negation of a battled monster's effect; Formats: TCG, OCG, MasterDuel, DuelLinks; Decks: 15 of 15 main deck, avg 1.33 copies, 11 distinct archetypes, 93.3% in gameplay type 7
- Observed: Top partners: Clockwork Night (46.7%), Limiter Removal (40%), Harpie's Feather Duster (40%), Monster Reborn (40%)
- Inferred: Primary role Utility with Board breaker secondary, from text; Portable across homes because the Machine restriction is broad; Low combo ceiling because it is a single +400 ATK gain
- 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
