Earthbound Geoglyph — Power Evaluation
Final Score: 53 ± 8 · Confidence: Medium
- Intrinsic: 52 · Deck: 54 · Meta: provisional

Why it scores here
Earthbound Geoglyph is a Field Spell whose value is a once-per-turn search of one Earthbound Immortal Spell/Trap when a Synchro Monster is Special Summoned, plus a Synchro-as-two-Tributes enabler. It converts Synchro summons into card advantage and tribute support, but it does not build a board or interact with the opponent, so its ATK-less body earns little on its own. The 48-deck footprint (62.5% in the Earthbound archetype) confirms the card is reliably played in its home, but per guardrail 3 that frequency reflects the archetype lock rather than inflating the score, and the Level 10 protection clause adds little to the rating.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 60 | Played in 48 of 48 sampled decks at an average of 1.75 copies, with 17 decks at 3 copies, but it is only live after a Synchro Summon, so it is not a free opening-hand card (observed; decks_evidence). |
| Combo & Conversion | 50 | The text converts one Synchro Summon into a Spell/Trap search and a Tribute enabler; no recorded boards exist to confirm the conversion depth (inference from text; combos_evidence is empty). |
| Resource Economy | 55 | The once-per-turn search is a net +1 card per qualifying Synchro Summon, and the Field Spell itself is not spent to use it (verified from text). |
| Effect & Interaction | 25 | Its only protection is conditional on Level 10 monsters being on the field and it does not affect the opponent's cards, so interaction is minimal (verified from text). |
| Material Utility | 25 | As a Field Spell it is not a material body; its only material-adjacent role is treating one Synchro Monster as two Tributes (verified from text). |
| Resilience & Flexibility | 40 | It stays on the field across turns, but a Field Spell is removed by field-removal effects and its protection depends on a Level 10 monster being present (inference from text). |
| Deck-Building Efficiency | 70 | A single slot with no garnet or lock requirement, and up to 3 copies appear in 17 decks, so redundancy is cheap (observed; decks_evidence copies_per_deck). |
Calculation
Weight profile: 0.7 Searcher/Tutor + 0.3 Extender. Intrinsic ≈ 52, Deck ≈ 54, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Searches an Earthbound Immortal Spell/Trap on each qualifying Synchro Summon, a net +1 card with no card cost
- Field Spell stays on the field, so the effect is reusable across turns (once per turn)
- Widely run in the sampled decks (48 of 48) at low copy counts, so it is cheap to include
- Tribute enabler lets a Synchro Monster count as two Tributes for Earthbound Immortal Tribute Summons
Weaknesses
- Search only triggers after a Synchro Summon, so it does nothing in a hand without a Synchro line
- Does not affect the opponent's board or cards; its interaction value is minimal
- Protection clause depends on Level 10 monsters being on the field
- No recorded boards, so its real conversion depth in practice is unconfirmed
Counters / choke points
- Field Spell removal, which removes the search and tribute enabler at once (inference)
- Disrupting the Synchro Summon itself, since the search requires the Synchro Summon to resolve (inference)
Best use
Field Spell searcher and Synchro-based tribute enabler for Earthbound Immortal lines. Decks: Earthbound (archetype 828), Earthbound (archetype 1408). Suggested copies: 1.
Evidence & gaps
- Verified: Searches one Earthbound Immortal Spell/Trap from the Deck when a Synchro Monster is Special Summoned, except during the Damage Step, once per turn (card text); Treats one Synchro Monster as two Tributes for an Earthbound Immortal Tribute Summon (card text); Cannot be targeted or destroyed by card effects while any Level 10 monster is on the field (card text)
- Observed: Included in 48 of 48 sampled decks, 62.5% in archetype 828 (decks_evidence); Copies distribution: 29 decks at 1, 2 at 2, 17 at 3; average 1.75 (decks_evidence); Top partner Earthbound Greater Linewalker appears in 68.8% of decks (decks_evidence)
- Inferred: The search is only reachable after a Synchro Summon, so its accessibility depends on the deck's Synchro line; As a Field Spell it is exposed to field-removal effects, which would end the search and tribute enabler; The archetype lock (Earthbound Immortal) limits its portability, so GenericUtility is capped despite 14 distinct archetypes
- 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 the deck sample only legal_copies not supplied per format
