D2 Shield — Power Evaluation
Final Score: 44 ± 8 · Confidence: Medium
- Intrinsic: 42 · Deck: 45 · Meta: provisional
- Primary role: Utility
Why it scores here
D2 Shield is a Normal Trap that doubles the DEF of one face-up Defense Position monster you control. It reliably turns a defensive board into a harder-to-attack one, and it is run in 16 of 16 sampled decks across 9 archetypes, which confirms it is a real, playable defensive trick. The score stays low because the text converts nothing into card advantage, board presence, or negation, and no combo evidence exists to show it doing more than a single buff; its high deck count reflects a generic defensive staple, not intrinsic power.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 50 | A set Trap that needs a face-up Defense Position monster; 16 of 16 decks run it at a 2.38 average copy count, so it is live often but conditional on a DEF monster being present (observed, inferred). |
| Combo & Conversion | 25 | The text only doubles one monster's DEF; no combo boards were supplied, so the conversion is text-only inference of a single buff (inferred). |
| Resource Economy | 20 | Spends a card to add DEF with no draw, search, or recovery in the text, so it is at best card-neutral (verified). |
| Effect & Interaction | 35 | Makes attacks into the buffed monster fail more often, which is soft defensive interaction rather than negation or removal (inferred). |
| Material Utility | 10 | A Trap card cannot be used as Xyz, Link, Fusion, or Synchro material, so it contributes nothing as a material body (verified). |
| Resilience & Flexibility | 35 | Depends on a monster surviving on the field and on the trap staying set; no negation-resistance data supplied (inferred). |
| Deck-Building Efficiency | 75 | A single Normal Trap with no garnets or locks, run at 1 to 3 copies across 16 decks, so it is cheap and clean to include (observed). |
Calculation
Weight profile: Utility / no clear role (default) profile. Intrinsic ≈ 42, Deck ≈ 45, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Cheap, clean defensive trick that fits 9 archetypes
- Doubling DEF makes attacks into the buffed monster fail more often
- Recurring partners are defensive support cards (Big Shield Gardna, Stone Statue of the Aztecs, Mirror Wall)
Weaknesses
- Needs a face-up Defense Position monster to target
- No card advantage, search, or negation in the text
- Contributes nothing as material and no combo evidence supports a larger role
Counters / choke points
- Anything that removes or moves the targeted monster, or stops the Trap being activated (inferred from text, not from evidence)
Best use
Defensive DEF-position support trap. Decks: Destiny HERO, Guardian, Labrynth, Solemn. Suggested copies: 2.
Evidence & gaps
- Verified: Text: doubles the DEF of one face-up Defense Position monster you control; Normal Trap with no material or search clauses; legal in TCG, OCG, MasterDuel, and DuelLinks; Run in 16 of the sampled decks at an average of 2.38 copies
- Observed: Appears in 9 distinct archetypes; Recurring partners are DEF-support and defensive cards (Big Shield Gardna, Stone Statue of the Aztecs, Mirror Wall, Wall of Disruption)
- Inferred: Works as a generic defensive trick rather than a core engine piece; Conditional accessibility on having a DEF-position monster out
- Data gaps: no combos supplied — combo conversion is text-only inference no guides supplied no banlist token — assumed 3 copies (unlimited) no usage statistics (StatisticsCard) — archetype inclusion % inferred from deck sample only
