Fossil Warrior Skull Bone — Power Evaluation
Final Score: 50 ± 8 · Confidence: Medium
- Intrinsic: 49 · Deck: 50 · Meta: provisional
- Primary role: Searcher/Tutor · Secondary: Boss/End-board
Why it scores here
Fossil Warrior Skull Bone is a Fusion monster that only enters play through Fossil Fusion, so its value depends on that enabler and on two Fusion materials being available. Its real conversion is the graveyard effect: banishing it adds Time Stream from the Deck, which is a net card-advantage line that works after the body has been removed. Its 2000 ATK and two monster attacks per Battle Phase add board pressure but earn little on their own, and the score would be higher without the Fusion access cost. The 211-deck sample with 97% co-occurrence with Fossil Fusion shows the card is consistently played in Fossil-adjacent homes, but that frequency is not used to inflate the score.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 45 | Cannot be Normal Summoned or searched directly and needs Fossil Fusion plus two Fusion materials; Fossil Fusion co-occurs in 97.2% of decks, so the route is usually live (observed deck stat, partly inferred). |
| Combo & Conversion | 40 | Text gives a two-attack-on-monsters Battle Phase on a Fusion body, but no recorded combo boards exist, so conversion is text-only inference (inferred). |
| Resource Economy | 65 | The GY banish adds one card from the Deck, a net +1 with no cost beyond the body, limited to once per turn (verified text). |
| Effect & Interaction | 5 | No negation, removal, or hand-trap effect in the text (verified text). |
| Material Utility | 15 | No evidence the Fusion body is used as material, and its Fusion restriction limits its material use (inferred). |
| Resilience & Flexibility | 50 | The GY effect still works after the body is destroyed or banished, but there is no protection and the card is one copy in 90% of decks (verified text + observed deck stat). |
| Deck-Building Efficiency | 60 | A single Extra Deck slot tied to Fossil Fusion, with no garnet or self-lock recorded; redundancy comes from the 32-archetype spread (observed deck stat, inferred). |
Calculation
Weight profile: 0.7 Searcher/Tutor + 0.3 Boss/End-board. Intrinsic ≈ 49, Deck ≈ 50, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Its GY effect adds one card from the Deck to hand, a net +1 that still works after the body is removed
- Used across 32 distinct archetypes in the sample, so it fits many Fossil-adjacent homes
- Two monster attacks per Battle Phase give it a finishing role on a board
Weaknesses
- Cannot be summoned from hand or Deck directly and depends on Fossil Fusion plus two Fusion materials
- Its GY effect is once per turn, and it is a weak interaction card with no negation or removal
- Played as a single copy in 191 of 211 decks, so it has little redundancy
Counters / choke points
- Any removal or banish effect that stops the Fusion Summon before it resolves
- Hand traps or Fusion-stopping effects that negate Fossil Fusion
Best use
Fusion attacker with a GY search for the Fossil archetype's Time Stream line. Decks: Fossil, Adamancipator, Chronomaly. Suggested copies: 1.
Evidence & gaps
- Verified: Must be Special Summoned with Fossil Fusion (card text); Can make up to 2 attacks on monsters during each Battle Phase (card text); GY banish adds 1 Time Stream from Deck to hand, once per turn (card text); Co-occurs with Fossil Fusion in 205 of 211 decks (97.2%) (deck stat)
- Observed: Included in 211 recent decks across 32 archetypes (deck stat); Single copy in 191 of 211 decks (deck stat)
- Inferred: Primary role is Searcher via GY banish, with Boss/End-board as secondary from the double attack; Fusion-only access makes accessibility moderate rather than high; Little material value as a Fusion body
- Data gaps: no combos supplied; combo conversion is text-only inference no guides supplied no banlist token; assumed 3 copies (unlimited) no usage statistics (StatisticsCard); archetype inclusion inferred from deck sample only format 7 meaning not labelled in evidence
