Xyz Double Back — Power Evaluation
Final Score: 37 ± 8 · Confidence: Medium
- Intrinsic: 38 · Deck: 36 · Meta: provisional
- Primary role: Recovery/Recursion
Why it scores here
Xyz Double Back is a narrow recursion spell. It needs a face-up Xyz you control to be destroyed during your turn while you control no monsters, then Special Summons that Xyz and a monster with lower or equal ATK from your Graveyard, both destroyed in the End Phase. It returns bodies for one turn rather than building a lasting board or gaining card advantage. The score does not come from the Xyz or ATK values involved. The two-deck sample confirms the card is playable but does not raise the score beyond what the text supports.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 35 | The empty-board and destroyed-Xyz trigger make it dead in many spots, and it has no searcher in the evidence; the two decks confirm it is in hand-plausible shells (inferred). |
| Combo & Conversion | 40 | The text converts one destroyed Xyz plus one low-ATK Graveyard monster into two temporary bodies, but no combo boards were recorded to confirm what that builds (inferred). |
| Resource Economy | 40 | Both summoned monsters are destroyed in the End Phase, so it gives tempo and recursion with no net card advantage; the cost is a spell slot (verified). |
| Effect & Interaction | 5 | The card has no negation, removal, or disruption effect (verified). |
| Material Utility | 25 | The summoned bodies are temporary and die in the End Phase, so their material value is limited to the current turn (inferred). |
| Resilience & Flexibility | 30 | The trigger requires an empty board on your turn and the summoned monsters are removed at End Phase, so it has one window per use with no recovery in the evidence (inferred). |
| Deck-Building Efficiency | 55 | It is a single spell with no garnet or lock, but its conditional trigger makes it a likely dead draw without Xyz on board (inferred). |
Calculation
Weight profile: Recovery/Recursion primary only; no secondary blend. Intrinsic ≈ 38, Deck ≈ 36, Meta = provisional. Modifiers: Self-restrictive condition (-2). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Brings back a destroyed Xyz monster and a low-ATK Graveyard monster in one card
- Single spell slot with no garnet or lock requirement
Weaknesses
- Needs an empty board and a destroyed face-up Xyz on your own turn
- Summoned monsters are destroyed in the End Phase, so there is no lasting board or card advantage
- No interaction or negation effect
Counters / choke points
- Board-wipe or removal that leaves no Xyz destroyed on your turn leaves it with no target
- Opponent interaction on the Graveyard targets limits the revival options (inferred)
Best use
Recursion tool for Xyz-based shells that can clear their own board and rebuild from the Graveyard. Decks: Maliss, Spright. Suggested copies: 1.
Evidence & gaps
- Verified: Text: during the turn a face-up Xyz Monster you control was destroyed, if you control no monsters, you may Special Summon a destroyed Xyz from the Graveyard and a monster with ATK less than or equal to it; Text: both summoned monsters are destroyed during the End Phase; Format: Quick-Play Spell, legal in TCG, OCG, MasterDuel and DuelLinks
- Observed: Appears in 2 decks, one Maliss and one Spright, each with 1 to 2 copies; Co-occurs with Knightmare Phoenix, Knightmare Cerberus and Evenly Matched in both decks
- Inferred: Its main role is Xyz recursion with a conditional empty-board trigger; The empty-board requirement makes it hard to use in most game states; Repeated use is possible through the End Phase reset, but no evidence shows it in practice
- Data gaps: No combos supplied, so combo conversion is text-only inference No guides supplied Only 2 decks in the sample, so archetype fit rests on a very small base No rulings supplied for the interaction between the empty-board condition and Xyz destruction timing No usage statistics (StatisticsCard); inclusion is inferred from the deck sample only No banlist token, so unlimited copies are assumed
