Chthonian Blast — Power Evaluation
Final Score: 45 ± 8 · Confidence: Medium
- Intrinsic: 46 · Deck: 47 · Meta: provisional
- Primary role: Removal
Why it scores here
Chthonian Blast is a reactive trap: it needs one of your face-up monsters destroyed and sent to the Graveyard before it does anything, then destroys the lowest-ATK face-up monster on the field and deals half that monster's ATK to both players. Its score comes from that conditional removal and its one-for-one trade, not from its nature as a trap. No combo or guide evidence was supplied, so combo conversion stays low, and the ATK of the monsters it can hit earns nothing. The recorded decks (4 of 5 Exosister, mostly 1 copy) show the role is real, but the sample is dated 2023 and cannot confirm current play.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 40 | Set trap that needs a destruction trigger on your own monster; no searcher or access route is supplied in the evidence (inferred from text). |
| Combo & Conversion | 30 | No combo boards recorded (appearances 0); it only converts a destruction event into one removal and damage (inferred from text). |
| Resource Economy | 45 | One opponent-or-field monster removed for one trap and one destroyed monster, roughly an even exchange; no refuel or draw (inferred from text). |
| Effect & Interaction | 45 | Hard removal for the lowest-ATK monster on any side, but gated by the destruction trigger and vulnerable to trap negation (verified text, inferred strength). |
| Material Utility | 10 | A trap card is never a material body and cannot be used as material (verified card type). |
| Resilience & Flexibility | 35 | Usable from set at any point the trigger fires, but a single negation ends it and its target choice is fixed to lowest ATK (inferred from text). |
| Deck-Building Efficiency | 55 | Single trap slot, 1 copy in 4 decks and 2 in one (observed deck sample); the trigger condition makes it a conditional slot rather than a clean one (observed + inferred). |
Calculation
Weight profile: Removal / Negation primary; no secondary role blended. Intrinsic ≈ 46, Deck ≈ 47, Meta = provisional. Modifiers: Duel Links not legal (-2). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Trigger and effect read cleanly from the card text (verified)
- Removal can hit any side's lowest-ATK face-up monster (verified text)
- Run in 4 of 5 recorded Exosister decks, so the role is practical (observed)
Weaknesses
- Requires one of your own monsters to be destroyed and sent to the Graveyard first (verified text)
- Can select your own lowest-ATK monster (verified text)
- Deck sample is from Jan–Jun 2023 and no usage statistics exist (verified from evidence)
- No combo or guide evidence, so conversion value is unverified (verified from evidence)
Counters / choke points
- Trap negation or removal of the setter before the trigger (inferred from text; no counter evidence supplied)
Best use
Reactive removal trap that punishes a destruction event by clearing the weakest face-up monster. Decks: Exosister. Suggested copies: 1.
Evidence & gaps
- Verified: Card text: destroy lowest-ATK face-up monster after your face-up monster is destroyed and sent to the GY; damage equal to half its ATK to both players; Card type is Trap Card; cannot be material; legal copies.duellink is 0; 5 decks in sample; 4 Exosister, 1 Ojama
- Observed: Present in 5 of 5 sampled decks (4 main-deck Exosister, 1 Ojama); 1 copy in 4 decks, 2 copies in 1; Top partners appear in 4 of 5 decks (80%)
- Inferred: Primary role is Removal from the conditional destroy-and-damage effect; Negation of the set trap would stop the effect; Accessibility is limited by the destruction trigger because no searcher is supplied
- Data gaps: No combos supplied: combo conversion is text-only inference No guides supplied No usage statistics (StatisticsCard) available Deck sample dated 2023-01-31 to 2023-06-28, about three years old Legality in TCG, OCG and Master Duel not supplied beyond the format list Only 5 decks in the sample
