Subterror Final Battle — Power Evaluation
Final Score: 43 ± 6 · Confidence: Medium
- Intrinsic: 42 · Deck: 44 · Meta: provisional
- Primary role: Utility · Secondary: Recovery/Recursion
Why it scores here
Subterror Final Battle converts a board of Subterror monsters into tempo: it repositions monsters, sets a Subterror monster's ATK/DEF to its combined original values, and stops Subterror effects from being negated this turn. Its text says it is set face-down instead of going to the GY, so one copy can be reused, which earns the resource and resilience points. The 400/400 deck inclusion and high archetype percentages do not raise the score: they reflect the card being locked to the Subterror archetype, which the evidence shows is 84% concentrated in three archetype IDs, and the card does nothing outside it. No combo evidence exists, so combo conversion is inferred from text only. It has no material value and no opponent interaction, so those axes stay low.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 50 | Needs Subterror monsters on the field to do anything, and appears in 52% of sampled decks at 2.07 copies average, but there is no as_starter or as_searched data (inferred). |
| Combo & Conversion | 35 | Text-only inference: position change, ATK/DEF equalisation, and no-negate protection on Subterror cards, with no recorded boards to confirm a payoff (inferred). |
| Resource Economy | 60 | Set face-down instead of going to the GY, so a single copy can be activated repeatedly; no direct card advantage or searches (verified from text, inferred for reuse value). |
| Effect & Interaction | 20 | No opponent-facing negation or removal; the only protective effect is that Subterror effects cannot be negated for the turn (verified from text). |
| Material Utility | 0 | A Trap card with no monster body, so it cannot serve as material (verified from text). |
| Resilience & Flexibility | 60 | Reusable across turns because it returns to the backrow, but dead outside Subterror and vulnerable to backrow removal (inferred from text and archetype lock). |
| Deck-Building Efficiency | 50 | No garnet or lock, and 2 copies is a common count, but it is a mild restriction because it is dead in non-Subterror decks (observed from deck copies, inferred for restriction). |
Calculation
Weight profile: 0.7 Utility + 0.3 Recovery/Recursion. Intrinsic ≈ 42, Deck ≈ 44, Meta = provisional. Modifiers: Archetype lock (-3). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Reusable: set face-down instead of going to the GY, so the card can be activated again later
- Four flexible modes: repositioning, ATK/DEF equalisation, and a no-negate protection clause
- Runs at 2 copies on average across 400 Subterror decks with no garnet cost
Weaknesses
- Only works with Subterror monsters on the field
- No opponent interaction and no material value
- No combo evidence, so its conversion value rests on text alone
- Its deck presence reflects archetype membership, not standalone strength
Counters / choke points
- Backrow removal or Trap destruction (generic inference; no counter data supplied)
- Opponent avoids committing Subterror monsters to the field (inferred)
Best use
Flexible Subterror backrow utility with reuse. Decks: Subterror. Suggested copies: 2.
Evidence & gaps
- Verified: Card text: four effects (reposition x2, ATK/DEF equalisation, no-negate clause) and set face-down instead of GY; Trap card, race Normal, no monster body; Present in 400/400 sampled decks, avg 2.07 copies (max 3); Archetype concentration: 52% + 19.5% + 12.2% of decks in the three Subterror archetype IDs
- Observed: Top partners are Subterror staples (Subterror Fiendess 100%, Subterror Guru 100%); Two guides mention the card, with one describing the Subterror backrow as important but not heavily dependent on backrow
- Inferred: Accessibility is archetype-gated and based on draw and set timing, since no starter or searched data exists; Combo conversion is text-only; no recorded boards confirm the payoff; Reuse value follows from returning to the backrow instead of the GY; Vulnerable to backrow removal, based on general reasoning
- Data gaps: no combos supplied: combo conversion is text-only inference no banlist token: assumed 3 copies (unlimited) no usage statistics (StatisticsCard): archetype inclusion % comes from the deck sample only no rulings data for the card the text does not specify the controller of the repositioned monsters; treated as unspecified
