When an opponent's Xyz Monster declares a direct attack: Special Summon 1 LIGHT Dragon-Type Xyz Monster from your Extra Deck in Attack Position, then the attacking monster attacks it instead, and you proceed to damage calculation. Its ATK becomes equal to the attacking monster's, also its effects are negated. You can only activate 1 "Double Dragon Descent" per turn.
Double Dragon Descent — Power Evaluation
Final Score: 49 ± 8 · Confidence: Medium
- Intrinsic: 50.3 · Deck: 48.2 · Meta: provisional
- Primary role: Removal / Negation · Secondary: Board breaker
Why it scores here
Double Dragon Descent is a narrow, reactive trap: it only triggers when an opponent's Xyz Monster declares a direct attack, and it converts that moment into a free LIGHT Dragon Xyz Monster from the Extra Deck plus a battle redirect and effect negation on the attacker. The score comes from that interaction (effect_interaction) and from a cheap, clean deck slot, not from any ATK value. The 4-deck sample and the absence of combo data keep the card from scoring higher, and the requirement of a live LIGHT Dragon Xyz in the Extra Deck caps accessibility.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 45 | Set-trap access is normal, but the card is live only when an opponent Xyz attacks and needs a LIGHT Dragon Xyz in the Extra Deck; 4 decks, all Galaxy/Photon-leaning (verified text; observed deck count; inferred narrowness). |
| Combo & Conversion | 30 | No combo boards recorded (0 appearances); it only turns one defensive trigger into one free Xyz body, so the conversion is text-only inference. |
| Resource Economy | 50 | Spends the trap and returns one Extra Deck monster for free, roughly card-neutral and a small gain only if the summoned Xyz is useful (verified text; inferred net value). |
| Effect & Interaction | 55 | Negates the attacking monster's effects and forces a battle redirect with ATK matched, which is strong against Xyz attacks but limited to that single trigger, once per turn (verified text). |
| Material Utility | 45 | The summoned body is a LIGHT Dragon Xyz that can itself act as Xyz material, but the option is narrow to one attribute and type (verified text; inferred). |
| Resilience & Flexibility | 35 | A trap can be negated before resolution, and it works only on one attack trigger per turn, so it is brittle against interruption (inferred from trap timing). |
| Deck-Building Efficiency | 60 | A single trap slot with no garnets or self-lock, but it presumes a LIGHT Dragon Xyz in the Extra Deck (verified text; inferred cost of the Extra Deck requirement). |
Calculation
Weight profile: 0.7 Removal/Negation + 0.3 Board breaker. Intrinsic ≈ 50.3, Deck ≈ 48.2, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Negates the attacking Xyz monster's effects and redirects the battle to a summoned Xyz, so it stops a direct Xyz attack cleanly.
- Summons a free body from the Extra Deck, so it costs no field space beyond the trap slot.
- Sits in a real Galaxy/Photon line: it appears in 3 of 4 sampled decks and co-occurs with Galaxy staples.
Weaknesses
- Triggers only on an opponent's Xyz direct attack, so it is dead against non-Xyz attackers and non-attacking turns.
- Requires a LIGHT Dragon Xyz Monster in the Extra Deck, which is a hard condition.
- Once per turn limit and trap timing leave it exposed to negation and to the opponent choosing not to attack.
Counters / choke points
- Negation traps that answer the activation before it resolves.
- Opponent non-Xyz attackers or effect-based removal that avoids the attack step.
Best use
Defensive trap for Galaxy/Photon Xyz decks facing a direct Xyz attack. Decks: Galaxy Photon. Suggested copies: 1.
Evidence & gaps
- Verified: Card text: Xyz direct-attack trigger, LIGHT Dragon Xyz Special Summon from Extra Deck, battle redirect, effect negation, once per turn.; Formats: TCG, OCG, MasterDuel, DuelLinks.
- Observed: Appears in 4 sampled decks, 3 of them Galaxy Photon, with 1.25 average copies per deck.; Top partners are Galaxy and Photon cards that co-occur in 3 of 4 decks.
- Inferred: Narrow trigger and Extra Deck requirement limit real accessibility.; Free summon offsets the trap's card cost, roughly even resource economy.; Trap timing and negation exposure lower resilience.
- Data gaps: no combos supplied — combo conversion is text-only inference no guides supplied no usage statistics (StatisticsCard) — archetype inclusion % inferred from deck sample only deck sample is only 4 decks, so deck synergy and resilience are weakly supported no banlist token — assumed 3 copies (unlimited)
