During the turn they are Special Summoned, Xyz Monsters you control cannot be destroyed by your opponent's card effects, also your opponent cannot target them with card effects. You can target 1 face-up Xyz Monster you control; it gains 300 ATK for each material currently attached to it, until the end of this turn, and if it does, and also has a material that is owned by your opponent, it can attack directly this turn (even if this card leaves the field). You can only use this effect of "Time Thief Hack" once per turn.
Time Thief Hack — Power Evaluation
Final Score: 46 ± 6 · Confidence: Medium
- Intrinsic: 45.3 · Deck: 46.5 · Meta: provisional
- Primary role: Boss / End-board · Secondary: Utility
Why it scores here
Time Thief Hack is a Continuous Spell whose value is conditional: it protects face-up Xyz Monsters from opponent card effects and, once per turn, adds 300 ATK per attached material to one face-up Xyz, granting a direct attack if that Xyz also holds an opponent-owned material. Its power comes from converting Xyz material into damage and board protection, not from its own stats, and it earns little for card advantage or material use. Its deck presence (400 of 400 sampled decks, typically one copy) confirms it is a practical single-slot support, but the absence of combo evidence keeps the combo and resilience scores moderate.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 55 | Present in all 400 sampled decks at a typical 1 copy across 50 archetype labels, but no searcher or starter route appears in the combo evidence (observed; the route itself is inferred). |
| Combo & Conversion | 45 | Text shows +300 ATK per material and a conditional direct attack, but no recorded board confirms its conversion rate (inferred from text). |
| Resource Economy | 20 | The card gives no draw, search, or GY refuel, so it produces no card advantage (verified from text). |
| Effect & Interaction | 40 | Protection from opponent card effects is real but limited to Xyz Monsters and only applies while it is on the field (verified from text). |
| Material Utility | 5 | As a Spell it cannot be used as material, so the score is near zero (verified from card type). |
| Resilience & Flexibility | 45 | It is a single face-up Continuous Spell and is removable; the direct-attack clause persists after it leaves the field, which helps slightly (verified from text). |
| Deck-Building Efficiency | 60 | It is a one-slot card with no garnet or lock and typically runs 1 copy, though it is tied to Xyz-based builds (observed from deck copies and text). |
Calculation
Weight profile: 0.7 Boss/End-board + 0.3 Utility. Intrinsic ≈ 45.3, Deck ≈ 46.5, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Protects face-up Xyz Monsters from opponent card effects and from being targeted by them, while it stays on the field
- Once-per-turn ATK boost scales with the number of materials on the chosen Xyz
- Direct-attack clause persists even if this card leaves the field
- Runs as a single copy in 400 of 400 sampled decks across 50 archetype labels
- No garnet or lock cost; cheap to include in Xyz builds
Weaknesses
- Only useful with a face-up Xyz Monster that already has materials
- Direct attack requires an opponent-owned material on the target Xyz
- No recorded combo evidence, so its real conversion rate is unmeasured
- No card advantage or recovery
- Vulnerable to Spell/Trap removal since it is a Continuous Spell
Counters / choke points
- Spell/Trap removal or negation of this Continuous Spell (inferred from its card type)
- Targeting or destroying the Xyz Monster by means that the protection does not cover, such as non-card effects (inferred from the text's scope)
Best use
Xyz protection and ATK-boost finisher. Decks: Time Thief (Xyz), Xyz-heavy builds seen in the sample: Utopia, Performage, RaidRaptor, Phantom Knights. Suggested copies: 1.
Evidence & gaps
- Verified: Continuous Spell with Xyz protection clause and once-per-turn ATK boost of 300 per material (card text); Legal in TCG, OCG, MasterDuel and DuelLinks (card formats)
- Observed: Present in 400 of 400 sampled decks, 1 copy in 362 of them, average 1.15 copies (deck evidence); Spread across 50 archetype labels, with 82.8% in gameplay type 7 (deck evidence); Usage statistics show 100% inclusion in 5 archetypes at typical 1 to 2 copies (usage statistics); Mentioned in 4 guides (guides evidence)
- Inferred: Finisher role comes from the ATK boost plus conditional direct attack (text plus rules reasoning); Accessibility from Time Thief search support, since partners are not confirmed as searchers in the evidence
- Data gaps: No combos supplied: combo conversion is text-only inference No banlist token; copy limit assumed 3 (unlimited) legal copies is empty for every format The 400-deck sample is 400 of 400, which suggests it was filtered on this card, so the 100% presence is not a population rate No searcher or starter evidence in the combo data No ruling or top-card ranking data The card text's first clause about the turn it is Special Summoned is ambiguous for a Spell and was read as given
