If a Beast-Type monster you control attacks a Defense Position monster, inflict piercing battle damage to your opponent. If you inflict battle damage to your opponent with this effect: Target 1 face-up monster your opponent controls; that target loses 500 ATK and DEF. (This remains even if this card leaves the field.)
Roaring Earth — Power Evaluation
Final Score: 42 ± 6 · Confidence: Medium
- Intrinsic: 49 · Deck: 48 · Meta: provisional
- Primary role: Floodgate/Control · Secondary: Removal, Utility
Why it scores here
Roaring Earth is a niche control card that provides persistent ATK/DEF reduction and piercing damage enablement in Beast-Type decks, but its value is heavily gated by strict archetype dependence and lack of combo potential. The persistent nature of the -500 ATK/DEF penalty is valuable for attrition-based control, but without hard removal or negation capabilities, it remains a soft interaction tool. Evidence shows only one Earthbound deck running it in the current sample, indicating limited meta presence despite theoretical potential in Beast-Type strategies.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 35 | Continuous Trap requiring Beast-Type monsters to activate; accessible card type but archetype-specific gating significantly reduces practical accessibility (inferred) |
| Combo & Conversion | 15 | No combo potential; purely passive effect that neither starts, extends, nor generates board presence independent of Beast-Type offense (verified) |
| Resource Economy | 45 | 1 card investment with repeated -500 ATK/DEF returns across multiple turns, roughly balancing resource cost without generating card advantage (inferred) |
| Effect & Interaction | 65 | Persistent -500 ATK/DEF debuff survives card removal and provides meaningful control in grindy games, though lacks hard removal or negation (verified) |
| Material Utility | 5 | Trap card cannot serve as Synchro/Xyz/Link material and retains zero utility when negated or removed (verified) |
| Resilience & Flexibility | 50 | Continuous Trap persists on field providing multi-turn value, but vulnerable to trap removal and limited to Beast-Type offense for activation (inferred) |
| Deck-Building Efficiency | 40 | Beast-Type archetype requirement restricts splashability; run at 2 copies in the single Earthbound deck sample (observed) |
Calculation
Weight profile: Floodgate/Control (single role). Intrinsic ≈ 49, Deck ≈ 48, Meta = provisional. Modifiers: Niche archetype requirement (-3); Limited deck sample (-2); No combo confirmation (-1). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Persistent ATK/DEF reduction survives card removal, providing long-term attrition value
- Synergizes clearly with Beast-Type monsters that attack Defense Position boards
- Continuous Trap mechanic enables multi-turn value generation without new activations
- Perfect inclusion rate in Earthbound sample (100% when deck runs it)
Weaknesses
- Archetype-exclusive design with no splashability outside Beast-Type
- Requires active Beast-Type offense to generate value; purely passive reactionary card
- Soft interaction only; -500 ATK/DEF reduction does not remove threats or negate plays
- Vulnerable to trap removal; cannot function if removed from field
Counters / choke points
- Trap removal (MST, Twin Twisters, Cosmic Cyclone)
- Non-attacking strategies avoiding Defense Position monsters
- Beast-Type engine disruption or suppression
Best use
Continuous trap providing persistent control and piercing damage in Beast-Type offense strategies. Decks: Earthbound. Suggested copies: 2.
Evidence & gaps
- Verified: Card type: Continuous Trap; Primary effect: Beast-Type monsters attacking Defense Position inflict piercing battle damage; Secondary effect: Reduce target face-up opponent monster ATK/DEF by 500 (persistent penalty survives card removal); Only 1 Earthbound deck in sample runs this card at 2 copies; Earthbound is the sole archetype represented in deck evidence
- Observed: 100% inclusion in the single Earthbound deck (1 of 1); Co-occurs exclusively with Beast-Type monsters (Uniflora, Ape Magician, King Tiger Wanghu, Berserk Gorilla, Green Baboon, Behemoth, Earthbound Immortal Cusillu); Top partners include Beast-Type creatures and field support (Closed Forest, Terraforming)
- Inferred: Primary role: Floodgate/Control based on continuous trap mechanic and persistent debuff; Accessibility gated by Beast-Type archetype requirement; Combo conversion near-zero; purely passive effect unsuitable as starter or extender; Not a generic staple; Beast-Type exclusive design; Soft control tool providing attrition, not hard removal or negation
- Data gaps: No combos supplied; combo conversion is text-only inference No guides supplied; no expert evaluations available No banlist information; assumed unlimited (3 copies) No usage statistics (StatisticsCard); archetype inclusion % limited to single-deck sample No top-card rankings; unable to assess format-wide meta presence Limited deck sample (1 deck) prevents confident generalization beyond Earthbound
