Why it scores here
Time Thief Flyback is a Time Thief-only trap whose value is converting Xyz material: it attaches a Time Thief from hand or Deck to a Time Thief Xyz, and from the GY it attaches an opponent's GY card, which gives it a recursion-style second use. It appears in 100% of the 4 recorded boards and in all 400 sampled decks, but it is never a starter or searched piece in those boards, so its score comes from being a steady engine in a single archetype. High ATK and popularity earned nothing here; the score rests on repeatable material conversion and the GY activation, while the lack of any negation keeps effect_interaction low.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 62 | Running in 400 of 400 sampled decks at 1.7 copies on average, with Time Thief partners at 100%, but it is never a starter or searched card in the 4 boards (observed; the GY banish route is verified from text). |
| Combo & Conversion | 60 | Present in 4 of 4 recorded boards with average power index 88, yet it is a non-starter piece in each (observed; the conversion is inferred from text). |
| Resource Economy | 60 | The GY banish plus opponent-GY material attach gives repeated material gain, and sampled boards show netCardAdvantage of 4 (verified from text; observed from boards). |
| Effect & Interaction | 25 | No negation or removal; only a mild denial by taking an opponent's GY card as material (verified from text). |
| Material Utility | 40 | A Trap that can be attached as material to Time Thief Xyz, but it is not a monster body and its value depends on the GY activation (inferred). |
| Resilience & Flexibility | 55 | The GY-activated effect survives a set-trap negation and works across turns, but it is capped at once per turn and only works with a Time Thief Xyz on board (verified from text; inferred). |
| Deck-Building Efficiency | 58 | Costs one or two slots in an archetype-locked deck with no garnet, but the Time Thief restriction limits splashing (verified from deck counts; inferred). |
Calculation
Weight profile: 0.7 Extender + 0.3 Recovery/Recursion. Intrinsic ≈ 55, Deck ≈ 58, Meta = provisional. Modifiers: Archetype-locked restriction (-2). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Present in every sampled Time Thief deck (400 of 400) and in 100% of recorded boards (observed)
- Converts opponent GY cards into Xyz material, a second use after banish from the GY (verified from text)
- Low slot cost at 1 to 2 copies per deck with no garnet (observed)
Weaknesses
- Never a starter or searched card in the recorded boards, so it does not start combos (observed)
- No negation or removal, so effect_interaction stays low (verified from text)
- Only once per turn, and the GY effect requires a Time Thief Xyz on board (verified from text)
Counters / choke points
- Negating the trap when it is set (inferred from text)
- Removing the Time Thief Xyz target before the GY effect resolves (inferred from text)
Best use
Material-adding trap that recurs from the GY to keep Time Thief Xyz monsters fed. Decks: Time Thief Xyz builds (archetype 644 and related Time Thief lines).
Evidence & gaps
- Verified: Text: attaches a Time Thief from hand or Deck to a Time Thief Xyz as material; Text: GY banish plus attach an opponent's GY card as material; Text: once per turn restriction; Deck running count 400 of 400, average 1.7 copies
- Observed: 4 of 4 combos present, avg power index 88, netCardAdvantage 4; Top partners at 100% co-occurrence (Time Thief Winder, Time Thief Regulator); Usage statistics show 100% inclusion in Time Thief lines
- Inferred: Recursion value from the GY banish route; Trap-based negation vulnerability
- Data gaps: Only 4 recorded combo boards, so combo centrality rests on a small sample No banlist token; assumed 3 copies (unlimited) No top-card ranking data for this card
