War Rock Mammud — Power Evaluation
Final Score: 52 ± 8 · Confidence: Medium
- Intrinsic: 50 · Deck: 54 · Meta: provisional
- Primary role: Board breaker · Secondary: Utility
Why it scores here
Mammud is a Level 5 EARTH Warrior whose only interaction is a once-per-turn destroy of one opponent Spell/Trap, and only after its own EARTH Warrior battles. That is a conditional one-for-zero trade with no card advantage, so the effect earns a moderate interaction score rather than a high one. Its 2000 ATK and 2000 DEF do not earn points; the score comes from its live presence in 142 recent decks, its clean single-copy slot cost, and its usefulness as a Level 5 Warrior body. No combo evidence exists, so the combo axis is kept low and rests on card text alone.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 55 | Appears in 142 of the recent decks across 21 archetypes, mostly War Rock, and is Normal Summonable without tribute under a Warrior-only condition, but no searcher or combo routes are recorded (observed, inferred). |
| Combo & Conversion | 35 | No recorded boards; the text only converts a battle into a Spell/Trap destruction plus a +200 ATK buff for War Rock monsters, with no board building (inferred). |
| Resource Economy | 40 | Destroys one Spell/Trap after battle with no recursion or draw, so the trade is roughly even at best and gives no repeated advantage (verified). |
| Effect & Interaction | 40 | Single once-per-turn destroy of one Spell/Trap, gated on the card battling, which is soft and easy to play around (verified). |
| Material Utility | 50 | A Level 5 EARTH Warrior is a generic material body that keeps its Level and attribute if its effect is negated, but no material usage is recorded (inferred). |
| Resilience & Flexibility | 40 | The effect requires a battle, is once per turn, and offers no redundancy across zones, so one negate or removal ends the effect (inferred). |
| Deck-Building Efficiency | 75 | Average 1.23 copies per deck with 119 of 142 decks running one copy, and the summon restriction is mild, so it is cheap to run (observed). |
Calculation
Weight profile: 0.7 Board breaker + 0.3 Utility. Intrinsic ≈ 50, Deck ≈ 54, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Live in 142 recent decks, mostly War Rock shells
- Single-copy slot cost, cheap to run
- Level 5 Warrior body usable as Synchro, Xyz or Fusion material
Weaknesses
- Effect requires its own EARTH Warrior to battle
- Once-per-turn limit and a single Spell/Trap destruction
- No recorded combo boards to confirm conversion
Counters / choke points
- Opponent Spell/Trap removal or set-trap bait prevents the destroy from having a target worth hitting
- Negating the effect leaves only a 2000 ATK body
Best use
Board breaker with a Warrior-only Normal Summon option. Decks: War Rock (archetype 389), War Rock (archetype 619), War Rock (archetype 192). Suggested copies: 1.
Evidence & gaps
- Verified: Effect text: Normal Summon without tribute under a Warrior-only condition; Effect text: once-per-turn destroy of one Spell/Trap after an EARTH Warrior battle; Average 1.23 copies per deck, 119 of 142 decks at one copy
- Observed: 142 recent decks run the card, 93.7% of them alongside War Rock Mountain; Top partner co-occurrence is high across War Rock support cards
- Inferred: Board-breaker role is the best fit for the battle-triggered destroy; Accessibility depends on the War Rock shell rather than a searcher
- Data gaps: no combos supplied, so combo conversion is text-only inference no banlist token, assumed 3 copies (unlimited) no rulings or metagame sample supplied guide evidence is one mention with no strength assessment
