Why it scores here
Closed Forest converts into a conditional ATK buff for Beast-Type monsters and a lock on Field Spell activation for both players. It does not draw, search, refuel, or create bodies, and the evidence has no combo records to show what it converts into in practice. Its score comes mainly from being a cheap, easy-to-run single copy with a field-spell lock that is situational and also restricts the player's own Field Spells. High ATK-buff text and broad deck counts did not earn points on their own; the 49-deck spread is treated as consistent inclusion, not proof of strength.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 55 | A Spell in hand with 49 recent decks across 24 archetypes at about 2 copies per deck, but no searcher or combo-start evidence (observed, inferred). |
| Combo & Conversion | 25 | The card only buffs Beast-Type monsters and creates nothing, and combos_evidence is empty, so conversion is text-only inference. |
| Resource Economy | 20 | No draw, search, or recursion; the GY-count buff is a stat effect rather than card advantage (verified from text). |
| Effect & Interaction | 40 | Field Spell lock hits opponent Field Spells but also the controller's own (verified from text); its interaction value depends on the opponent's field-spell use, which the evidence does not measure (inferred). |
| Material Utility | 10 | Not a monster and cannot serve as material (verified from card type). |
| Resilience & Flexibility | 35 | Single-zone field presence that can be destroyed; the lock persists only while it remains on the field (inferred from text). |
| Deck-Building Efficiency | 70 | Single-card, no garnet, no brick risk; the lock can hinder the player's own Field Spells, a mild restriction (verified from text, inferred for the cost). |
Calculation
Weight profile: 0.7 Floodgate/Control + 0.3 Utility. Intrinsic ≈ 44, Deck ≈ 41.65, Meta = provisional. Modifiers: Self-locking restriction (-2). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Cheap to run: one copy, no garnets, and it appears in 49 recent decks across 24 archetypes (observed).
- Field-spell lock gives a flexible answer to Field Spell use from the opponent (verified from text).
Weaknesses
- No combo, guide, or usage-statistic evidence shows what it converts into beyond a conditional ATK buff.
- Its effect is limited to Beast-Type monsters and to decks that use Field Spells, so value is situational.
- The lock restricts the controller's own Field Spells (verified from text).
Counters / choke points
- Destruction or banishing of the Field Spell itself, which ends the buff and the lock (inferred from text).
Best use
Floodgate / Control, with a conditional Beast-Type ATK buff. Decks: Solemn, Tri-Brigade, Supreme King, Lady of Lament, Dinomorphia, Simorgh, Exodia, Destiny HERO, Elemental HERO, Spright. Suggested copies: 2.
Evidence & gaps
- Verified: Card text: Beast-Type ATK gain per GY monster; Field Spell activation lock for both players; the lock is still active on the turn the card is destroyed.; 49 decks, 24 archetypes, copies per deck avg 2 (distribution 1:17, 2:15, 3:17).
- Observed: Gameplay split across 3 gameplay types (about 31–33% each); top partners are generic staples (Solemn Judgment 57%, Harpie's Feather Duster 43%).
- Inferred: The lock restricts the controller's own Field Spells as well as the opponent's.; Accessibility is live in hand, but no searcher route is recorded.
- 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 recorded Field Spell interaction data — effect_interaction is text-based
