Time Thief Perpetua — Power Evaluation
Final Score: 60 ± 6 · Confidence: Medium
- Intrinsic: 53 · Deck: 64 · Meta: provisional
- Primary role: Boss/End-board · Secondary: Recovery/Recursion
Why it scores here
Perpetua does not score for its 1900 ATK or its Rank 4 body. It scores because its Standby effect converts a spent material into a Time Thief from the Graveyard, and its Quick effect pulls a Time Thief from the Deck as new material, so one Xyz keeps producing card advantage and board presence. Combo evidence supports this as a payoff in all 4 recorded boards (power index 100 in the 2-card lines, net card advantage +4), and its partners are near-universal in the attached decks. It scores low on effect interaction and material utility, because it has no negation or removal and is a poor generic material.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 58 | Live through Time Thief Xyz summons in 124 of 400 decks plus 27 more Time Thief-labelled decks, but never a searcher or starter in combos (observed). |
| Combo & Conversion | 78 | Payoff in 4 of 4 recorded combos with average power index 88 and end-board presence (observed). |
| Resource Economy | 80 | Standby effect recycles a Time Thief from the GY and the Quick effect adds a Time Thief from the Deck as material, giving repeated advantage (verified text, observed net +4 in boards). |
| Effect & Interaction | 15 | No negation, removal, or hand-trap reach in its text; the body only pressures the board (verified). |
| Material Utility | 25 | Rank 4 Xyz with no recorded use as material; it is not a clean generic material (inferred). |
| Resilience & Flexibility | 50 | Two once-per-turn effects in different phases give multi-turn value, but nothing protects the effects from a single negate (inferred). |
| Deck-Building Efficiency | 62 | Usually 1 copy and no garnet or lock evidence, but it needs Time Thief support to run (observed plus inferred). |
Calculation
Weight profile: 0.7 Boss/End-board + 0.3 Recovery/Recursion. Intrinsic ≈ 53, Deck ≈ 64, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Recurs a Time Thief from the GY each Standby Phase, so one Xyz keeps producing value
- Quick effect adds a Time Thief from the Deck as material, a deck-to-board conversion
- Appears as payoff in every recorded combo sample with a high average power index
- Near-universal partners in the attached decks (Winder 96.8%, Regulator 95.5%)
Weaknesses
- No negation, removal, or hand-trap reach
- Weak as material for other summons (no recorded use)
- Effects depend on Time Thief support in the Graveyard and Deck
- Combo sample is thin (4 boards), so the conversion read is uncertain
Counters / choke points
- The evidence pack names no specific counter cards; the body and effects carry no opponent-facing interaction that would need to be played around.
Best use
Boss/End-board piece that recurs Time Thief value each turn. Decks: Time Thief (Xyz gameplay, type 7), Time Thief Rush and Duel Links variants. Suggested copies: 1.
Evidence & gaps
- Verified: Standby Phase effect: detach 1 material, Special Summon a Time Thief from the GY (not itself); Quick effect: target another Xyz you control, attach a Time Thief from the Deck as material; Each effect is once per turn; Rank 4, 1900 ATK / 2500 DEF, DARK Psychic Xyz; Used as a Time Thief payoff in 400 of 400 sample decks
- Observed: Payoff and end-board role in 4 of 4 recorded combos, average power index 88; Net card advantage +4 in the example boards; Partner rates: Winder 96.8%, Regulator 95.5%, Bezel Ship 93.2%; Time Thief Xyz inclusion 100% across the usage statistics for the main Time Thief homes
- Inferred: Accessibility depends on Rank 4 summons from Time Thief-compatible monsters; Material utility is poor because the card is a Xyz body with no recorded material use; Resilience is limited because one negate can stop the two effects
- Data gaps: no banlist token; assumed 3 copies (unlimited) combo sample is only 4 boards, so combo conversion is thin no rulings or counter evidence in the pack no dated metagame sample; meta power left null
