Barrel Behind the Door — Power Evaluation
Final Score: 43 ± 6 · Confidence: Medium
- Intrinsic: 43 · Deck: 42 · Meta: provisional
- Primary role: Negation/Interaction
Why it scores here
Barrel Behind the Door redirects damage from a damage-inflicting effect to the opponent, but its activation condition is narrow and its text builds no board, material, or card advantage. No combo boards were recorded, so nothing confirms it converts into practical wins beyond a one-slot reaction. Its score rests on being a one-copy trap that appears in 57 decks across 37 archetypes and costs almost nothing to run; having no ATK or DEF earns it no points either way.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 50 | Set in the backrow and run in 57 decks, mostly at one copy, so it is reliably available but needs a set turn and an opposing damage effect to trigger (observed). |
| Combo & Conversion | 5 | No recorded boards or combo examples exist, and its text only redirects damage without building anything (inferred). |
| Resource Economy | 35 | It costs a card and returns no draw, search, or refuel, so the exchange is roughly even at best (inferred). |
| Effect & Interaction | 35 | It answers damage-inflicting effects cleanly but is blank to non-damage plays and to battle damage as the text is written (verified). |
| Material Utility | 0 | It is a Trap Card and cannot be used as material (verified). |
| Resilience & Flexibility | 30 | It is a single face-down trap with no redundancy or multi-zone reach, and nothing in the text protects it from backrow removal (inferred). |
| Deck-Building Efficiency | 80 | It is a single slot in 50 of 57 decks, carries no garnet or lock restriction, and splashes easily (verified). |
Calculation
Weight profile: Primary role Negation/Interaction only; no secondary blend. Intrinsic ≈ 43, Deck ≈ 42, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Clean, cheap answer to damage-inflicting effects
- Near-zero deckbuilding cost, one copy fits most homes
- Present in 57 decks across 37 archetypes, so it is a live tech choice
Weaknesses
- Narrow activation: only effects that inflict damage
- Creates no board, material, or card advantage
- No recorded combo boards to confirm practical conversion
Counters / choke points
- Opponent plays no damage-inflicting effects, so the card has no target
- Battle damage and non-damage plays fall outside the text
- Backrow removal or negation before it is needed
Best use
One-of anti-damage tech in interaction-heavy decks. Decks: Solemn, Hole, Greed. Suggested copies: 1.
Evidence & gaps
- Verified: Text: redirects damage from effects that would inflict damage to you, and only when such an effect is activated; Trap Card with no material use; Run as one copy in 50 of 57 decks
- Observed: Present in 57 of the attached decks across 37 archetypes; Co-occurs with Debunk, Drastic Drop Off, Ultimate Providence, and Wiretap in 38 of 57 decks
- Inferred: Narrow reactive role that adds no board or card advantage; Vulnerable to backrow removal since its text gives no protection; Deck value is limited to interaction-heavy shells
- Data gaps: no combos supplied, so combo conversion is text-only inference no guides supplied no banlist token, so 3 copies assumed no usage statistics (StatisticsCard), so inclusion is from the deck sample only no top-card data supplied no legal copies per format supplied starter count and power index unavailable without combos
