Mountain — Power Evaluation
Final Score: 34 ± 8 · Confidence: Medium
- Intrinsic: 37 · Deck: 36 · Meta: provisional
- Primary role: Utility
Why it scores here
Mountain is a generic Field Spell that grants a flat +200 ATK/DEF to every Dragon, Winged Beast, and Thunder monster on the field, so it converts almost nothing into winning value: it builds no board (0 combos recorded), trades no cards, and offers no disruption. Its only real merits are accessibility — a condition-free Spell searchable via Terraforming (51.2% co-deck) — and clean deck-building cost, which is why it shows up in 43 sampled decks across 15 archetypes. Those inclusion numbers confirm the card is reachable and splashable, not that it is strong; the ATK/DEF boost rarely changes outcomes and it also buffs the opponent's qualifying monsters, so the high deck count does not inflate the score. The evaluation is driven by function, not by stats.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 58 | Generic Field Spell with no conditions, live as soon as it is drawn and searchable via Terraforming (51.2% co-deck), though most lists only run 1-2 copies (observed). |
| Combo & Conversion | 15 | Combo evidence records 0 appearances, 0 starter role, and 0 material role; a blanket +200 ATK/DEF does not build a board on its own (observed). |
| Resource Economy | 15 | Provides a single persistent boost with no card advantage, search, or GY refuel, making the exchange roughly even-to-negative (inferred). |
| Effect & Interaction | 8 | Offers no disruption, negation, or removal toward the opponent; the effect is purely statistical (verified). |
| Material Utility | 5 | As a Field Spell it cannot be used as monster material or as a name/level provider for Extra Deck plays (verified). |
| Resilience & Flexibility | 25 | Persists face-up across turns as a Field Spell but is removed by any Spell/Trap removal and offers no recovery or multi-zone utility (inferred). |
| Deck-Building Efficiency | 55 | Cheap to slot — no cost, no lock, no once-per-turn, redundant copies fine — yet it still occupies 1-2 slots for negligible impact (inferred). |
Calculation
Weight profile: Utility / no clear role (default) — Mountain is a generic stat-boost Field Spell with no combo, starter, or interactive role. Intrinsic ≈ 37, Deck ≈ 36, Meta = provisional. Modifiers: Symmetric blanket boost (-2). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Generic Field Spell with no cost, no lock, and no once-per-turn clause, so it is trivially splashable in any deck
- Searchable via Terraforming (present in 51.2% of its decks), giving reliable access
- Persistent blanket +200 ATK/DEF for Dragon, Winged Beast, and Thunder monsters across turns
- Redundant copies are fine and it never bricks a hand
Weaknesses
- Minimal impact on the game: a flat 200 ATK/DEF rarely changes combat outcomes or board states
- Symmetric — it also boosts the opponent's Dragon, Winged Beast, and Thunder monsters
- No disruption, negation, removal, or card advantage
- 0 recorded combo appearances mean it contributes nothing to combo lines or end boards
- Dead card in decks that do not field Dragon, Winged Beast, or Thunder monsters
Counters / choke points
- Any Spell/Trap removal (e.g. Mystical Space Typhoon, Harpie's Feather Duster) strips it before it matters
- Decks that do not field Dragon, Winged Beast, or Thunder monsters ignore its boost entirely
- Negating Terraforming denies the search route when only 1-2 copies are drawn
- Opponent decks with the same monster types benefit from the symmetric buff
Best use
Minor stat-boost Field Spell / utility filler. Decks: Blue-Eyes, Dragunity, Rokket, Malefic, Vanquish Soul. Suggested copies: 1.
Evidence & gaps
- Verified: Card text: all Dragon, Winged Beast, and Thunder monsters on the field gain 200 ATK/DEF; Type: Spell Card, Field subtype, no archetype, no ATK/DEF body (0/0); Legal in TCG, OCG, Master Duel, and Duel Links; No cost, no once-per-turn clause, and no lock in the card text
- Observed: 43 sampled decks run Mountain, all in the main deck, averaging 1.91 copies; 15 distinct archetypes appear, most notably Fairy Tail (34.9%) and Vanquish Soul (18.6%); Terraforming is a top partner at 51.2% co-deck, confirming a search route; 0 combo appearances, 0 starter role, 0 material role, and no guides mention it
- Inferred: The symmetric boost also strengthens the opponent's qualifying monsters, reducing net value; The card functions as a slot filler / minor stat boost rather than a starter, payoff, or interaction piece; Reachable via Terraforming into a 1-2 copy slot, giving moderate but not high reliability
- 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 no dated metagame sample, so meta power is null/provisional
