Crystal Skull — Power Evaluation
Final Score: 49 ± 8 · Confidence: Medium
- Intrinsic: 50 · Deck: 48 · Meta: provisional
- Primary role: Searcher/Tutor · Secondary: Material body
Why it scores here
Crystal Skull's power is its conditional search: at End Phase, if it took no effect damage that turn, it adds or Special Summons a 0-ATK Rock from the Deck. That is a modest, once-per-turn tutor with a real cost (1000 damage on Summon, which also forces Defense Position) and a timing condition that must be checked each turn. The body is a Level 1 Water Rock with no interaction, so it earns little beyond accessibility and cheap deck slots. It appears in 9 of the sampled decks at about 2.1 copies each across 3 archetypes, which confirms it is a practical pick, but that frequency does not raise the score. No combo evidence was supplied, so conversion is scored from text only.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 55 | Summoned on its own with a 1000-LP cost and an End Phase no-damage condition; it appears in 9 decks at avg 2.11 copies, so it is routinely reachable (observed + inferred). |
| Combo & Conversion | 35 | The text only converts into a 0-ATK Rock from the Deck and no further board is described; no combo boards exist to confirm more (inferred). |
| Resource Economy | 45 | Converts one card into one card, paying 1000 LP and gaining no advantage on the field; a modest, conditional refuel at best (verified from text). |
| Effect & Interaction | 5 | No negation, removal, or hand-trap effect is described in the text (verified from text). |
| Material Utility | 40 | Level 1 Water Rock with no Tuner text; a usable low-level body, but nothing in the text makes it a clean generic material (inferred). |
| Resilience & Flexibility | 35 | Its effect fires only at End Phase under a damage condition, and it is a single-spot body with no redundancy shown in the sample (inferred). |
| Deck-Building Efficiency | 75 | Runs 1–3 copies with no garnet or lock restriction, so it is cheap to include in a deck that can use it (observed). |
Calculation
Weight profile: Primary role Searcher/Tutor (0.7 weight) blended with secondary Material body (0.3) — 0.7·Searcher + 0.3·Material. Intrinsic ≈ 50, Deck ≈ 48, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Conditional End Phase tutor for a 0-ATK Rock monster from the Deck
- Cheap to run with no garnet or restriction, and copies are routinely 1–3
Weaknesses
- Costs 1000 LP and forces Defense Position on Summon
- Search only triggers if no effect damage was taken that turn
- No interaction and no combo evidence to show board conversion
Counters / choke points
- Effect damage taken earlier in the turn blocks the End Phase search
- Standard hand traps and negations do not need to target it to remove its value
Best use
Conditional Searcher / 0-ATK Rock tutor. Decks: Adamancipator, Exosister. Suggested copies: 2.
Evidence & gaps
- Verified: Crystal Skull's on-Summon 1000 damage and Defense Position change, and its End Phase conditional search of a 0-ATK Rock, are stated in the card text; Card is Level 1 Water Rock Effect Monster with 0 ATK/DEF
- Observed: Appears in 9 sampled decks, 4 at 3 copies and 4 ... distribution 1:4, 3:5, avg 2.11; Spans 3 archetype buckets (Adamancipator x2, Exosister) and 2 gameplay types
- Inferred: Practical accessibility is real but conditional on the End Phase no-damage check; Searched 0-ATK Rock access is the core value; no combo evidence confirms the route
- 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 no banlist token — assumed 3 copies (unlimited)
