Heavy Slump — Power Evaluation
Final Score: 50 ± 8 · Confidence: Medium
- Intrinsic: 49 · Deck: 51 · Meta: provisional
- Primary role: Hand trap
Why it scores here
Heavy Slump is a single trap whose effect is a forced hand reset: if the opponent holds 8 or more cards, they shuffle their whole hand into the Deck and draw 2. The effect axis is held to 40 because that 8-card threshold is conditional and, by the text alone, rarely met in ordinary play. Its spread across 400 sampled decks and 97 archetypes confirms it is an accessible, cheap tech slot, but that frequency did not raise the score. As a non-monster it has no ATK, material or combo value, so those axes stay low.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 45 | Trap that must be drawn or set; no searcher or recursion route appears in the evidence, and it is in 400 of 400 sampled decks (observed, with a suspected sampling artifact noted in data_gaps). |
| Combo & Conversion | 15 | No combo boards recorded (total_combos 0) and no combo-level text beyond its hand reset, so conversion is text-only inference (inferred). |
| Resource Economy | 45 | Costs one card and disrupts the opponent's hand tempo, but gives the opponent 2 draws, so it is roughly even in card terms (inferred from text). |
| Effect & Interaction | 40 | Strong hand disruption when its 8-card condition is met, but that condition is conditional and not commonly met per the text (verified text, inferred frequency). |
| Material Utility | 5 | A trap card cannot be used as material and has no level, attribute or name-providing role (verified from card type). |
| Resilience & Flexibility | 30 | Single-copy trap with no redundancy or recovery; one negation ends it, and its trigger depends on opponent hand size (inferred). |
| Deck-Building Efficiency | 75 | Single-copy trap with no garnet, lock or restriction, and it sits in a generic slot across many archetypes (observed, deck spread). |
Calculation
Weight profile: Hand trap primary, no secondary role. Intrinsic ≈ 49, Deck ≈ 51, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Forces a large hand reset against hand-heavy opponents
- Cheap, single-copy slot that fits many archetypes
- Trap card with no ATK, level or material requirements to satisfy
Weaknesses
- 8-card hand condition is conditional and rarely met in ordinary play
- Gives the opponent 2 draws after the reset
- No combo or starter role; scoring rests on text alone
Best use
Hand trap / tech trap against hand-heavy opponents. Decks: Synchron, Onomat, Ryzeal, Junk. Suggested copies: 1.
Evidence & gaps
- Verified: Card text: opponent with 8 or more cards in hand shuffles their hand into the Deck and draws 2; Card type is Trap Card; no ATK, DEF, level or link; Formats: TCG, OCG, MasterDuel, DuelLinks; Sampled decks: 400 of 400 run it, average 1.33 copies, 97 distinct archetypes; usage_statistics: Utopia (gameplay 4) at 100% inclusion, typical 1 copy
- Observed: Top partners by co-deck share: Ash Blossom & Joyous Spring 91%, Mulcharmy Fuwalos 88.8%, Called by the Grave 88.2%; Archetype spread: Synchron 9%, Onomat 8.5%, Ryzeal 7.2%, Junk 7.2%
- Inferred: Role is a hand trap: it punishes hand size rather than negating or removing cards; The 8-card condition is rarely met in ordinary play, which caps the effect axis; Net effect is tempo and hand reset rather than card advantage for the controller
- Data gaps: No combos supplied (total_combos 0); combo conversion is text-only inference No guides supplied 400 of 400 sampled decks running it looks anomalous and should be checked against the matching reference legal_copies lists only duellink; no copy limits given for TCG, OCG or MasterDuel usage_statistics has only one Utopia row, which does not reconcile with 97 archetypes in decks_evidence No hand-size rules for MasterDuel or DuelLinks in the evidence, so the 8-card threshold's real-game frequency is inferred No rulings or Rulling/Point data available
