Why it scores here
Unending Nightmare is a reusable removal engine: a Continuous Trap that pays 1000 LP to destroy any face-up Spell/Trap, repeatable once per Chain as long as it stays on the field. It appears in all 400 sampled decks (avg 1.57 copies) and across 114 distinct archetypes, confirming it is a genuinely generic control/grind tool rather than a niche pick. However, it builds no board and has zero combo appearances, so its value is limited to trading 1-for-1 against the opponent's face-up backrow. Its blank 0/0 body and face-up-only targeting keep it out of higher tiers — its high play rate earns no power points on its own.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 50 | As an unsearchable Continuous Trap it is only live when drawn or set, with no combo routes present (no as_starter data) (inferred). |
| Combo & Conversion | 15 | combos_evidence shows 0 appearances and 0 as_starter/as_material/as_payoff, so it contributes nothing to building a board (observed). |
| Resource Economy | 52 | Each activation is a 1-for-1 destruction for 1000 LP while the Continuous Trap stays to be reused, giving recurring but card-neutral value (verified). |
| Effect & Interaction | 52 | Text lets it destroy any face-up Spell/Trap, but only face-up cards are targetable and it is once per Chain, so it cannot hit set backrow (verified). |
| Material Utility | 5 | As a Continuous Trap it provides no body, Level, or Attribute material and locks nothing (verified). |
| Resilience & Flexibility | 50 | It persists on the field and can be re-activated once per Chain, but a single backrow removal or negate ends it and it is slow by one turn (inferred). |
| Deck-Building Efficiency | 60 | One clean slot with no archetype lock and no garnet; avg 1.57 copies across 114 archetypes confirms it is cheap to include (observed). |
Calculation
Weight profile: 0.7 Removal/Negation + 0.3 Floodgate/Control. Intrinsic ≈ 54.6, Deck ≈ 55.5, Meta = provisional. Modifiers: Splashable generic control tech (1). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Recurring face-up Spell/Trap destruction that stays on the field for repeated use
- Completely generic: no archetype requirement, valid across 114 distinct archetypes
- Cheap to run at a single slot with no garnet or lock
- Hits Field Spells, Continuous/Equip Spells, Pendulum scales and Continuous Traps including opposing floodgates
Weaknesses
- Cannot target face-down cards, so it misses set backrow entirely
- Costs 1000 LP per activation, adding up in long games
- Slow: needs to be set and survive a turn before it can interact
- Builds no board and has zero combo evidence
Counters / choke points
- Backrow removal such as Harpie's Feather Duster or Lightning Storm
- Negating its activation or destroying it before it resolves
- Decks that rely on monster effects or face-down backrow rather than face-up Spells/Traps
- Quick-effect chains that resolve their face-up Spells/Traps before the destruction lands
Best use
Reusable face-up Spell/Trap removal in control and grind decks. Decks: True Draco, Runick (Mysterune), Labrynth, Machina, Train, Scrap. Suggested copies: 2.
Evidence & gaps
- Verified: Card text: Continuous Trap that pays 1000 LP to target and destroy 1 face-up Spell/Trap, once per Chain; Card has 0 ATK / 0 DEF and is not a monster body; Runs in 400 sampled decks in the main deck, avg 1.57 copies (max 3); usage_statistics: True Draco inclusion 55.6% at typical 1 copy
- Observed: 114 distinct archetypes include the card, confirming generic portability; Zero combo appearances across recorded boards (no starter/material/payoff role); Top partners are generic control traps and hand traps (Infinite Impermanence 59.5%, Skill Drain 48.8%)
- Inferred: Face-up-only targeting means it cannot answer set backrow; The 1000 LP cost and one-turn set-up gate it to slower control/grind decks; Repeatable activation on a persistent Continuous Trap gives recurring 1-for-1 interaction
- Data gaps: no combos supplied — combo conversion is text-only inference no guides supplied no banlist token — assumed 3 copies (unlimited)
