Why it scores here
Clockwork Night is a continuous Spell whose main value is a board-wide Machine conversion with a +500/-500 ATK/DEF swing, plus a once-per-turn graveyard search for an EARTH Machine. It is in every recorded combo and in 400 of 400 sampled decks across 53 archetypes, which confirms it is reliably accessible and practical, but the combo data assigns it no starter, searched, material or payoff role, so the 94.1 average power index of its boards is not credited to the card. Its ATK/DEF swing is a soft, non-negating interaction, and its self-applied Machine type change restricts the player's own non-Machine engines, which is why deck-building cost is only mid-range.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 68 | Live in 400/400 sampled decks at about 1.23 copies per deck and present in all 10 recorded combos, with a graveyard route from banish-and-discard (Observed). |
| Combo & Conversion | 55 | Present in all 10 combos, but combo role is empty and the 94.1 average power index is a board-level correlation, so it is scored as a modest board-wide buff only (Inferred). |
| Resource Economy | 55 | The graveyard effect banishes itself and discards one card to add one EARTH Machine, which is roughly even card economy with a recurring route (Verified). |
| Effect & Interaction | 45 | The continuous effect gives -500 ATK/DEF to opposing Machines and turns all face-up monsters into Machines, which is soft interaction with no negation or removal (Verified). |
| Material Utility | 5 | A Spell cannot be used as material, so this axis scores only the minimal value of a non-body card (Verified). |
| Resilience & Flexibility | 55 | Its graveyard effect lets it recur after it leaves the field, but as a face-up continuous Spell it can be removed by ordinary spell/trap removal (Inferred). |
| Deck-Building Efficiency | 55 | Typically one copy with no garnet requirement, but the Machine type change also affects the player's own non-Machine monsters and guide notes say it is hard to mix with other engines (Observed/Inferred). |
Calculation
Weight profile: 0.7 Utility + 0.3 Searcher/Tutor. Intrinsic ≈ 54, Deck ≈ 57, Meta = provisional. Modifiers: self-locking restriction (-3). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Live in every sampled deck and every recorded combo, so the card is reliably accessible
- Board-wide ATK/DEF swing of +500 for own Machines and -500 for opposing Machines
- Graveyard recursion with a once-per-turn search for an EARTH Machine
Weaknesses
- No starter, searched, material or payoff role recorded in combo data, so its contribution is not isolated
- Type change restricts the player's own non-Machine monsters
- Continuous field Spell is vulnerable to ordinary spell/trap removal
Counters / choke points
- Spell/trap removal or destruction of the face-up continuous Spell
- Non-Machine monster engines that ignore the Machine type change
Best use
Board-wide Machine support with graveyard search. Decks: Cyber Dragon, Cyberdark, Infinitrack, Machina, R.B.. Suggested copies: 1.
Evidence & gaps
- Verified: Continuous Spell effect: all face-up monsters become Machine, Machine you control gains 500 ATK/DEF, opposing Machine loses 500 ATK/DEF; Graveyard effect: banish this card, discard 1 card, add 1 EARTH Machine from Deck to hand, once per turn; 400 of 400 sampled decks run it in the main deck, 53 distinct archetypes
- Observed: Average 1.23 copies per deck; 331 decks run one copy; Appears in 10 of 10 recorded combos, with no starter, searched, material or payoff role tagged; Usage statistics show 100% inclusion in several archetypes at 1 copy each
- Inferred: Acts as a board-wide Machine support piece and graveyard searcher rather than a starter; Its effect on opposing monsters is soft interaction, not negation or removal
- Data gaps: No banlist token; assumed 3 copies (unlimited) Combo combo role is empty for every example, so starter/searched/payoff roles cannot be confirmed No ruling or FAQ evidence for the type-change interaction with face-up monsters Guide mentions are thin and partly about other cards (Cyber Dragon support, R.B. floodgate)
