Electromagnetic Turtle — Power Evaluation
Final Score: 55 ± 6 · Confidence: Medium
- Intrinsic: 56 · Deck: 54 · Meta: provisional
- Primary role: Board breaker / Going-second · Secondary: Recovery/Recursion
Why it scores here
Electromagnetic Turtle is a graveyard-activated Quick Effect that ends the opponent's Battle Phase once per Duel, so its value is a single defensive stop that only works after the card is already in the graveyard. The card does not build a board, gain card advantage, or negate anything, so the score sits in the interaction and deckbuilding axes. Its 400-of-400 deck inclusion and 74 archetypes confirm it is a cheap, portable one-copy slot, but that frequency is not treated as proof of strength; the sample also looks anomalous and needs checking. The high ATK-free body and DEF 1800 earn no points on their own.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 55 | Live only once it is in the graveyard, which the text does not provide a route for beyond discards or sends; widely run in the sample (verified deck count, observed, but unverified as a route). |
| Combo & Conversion | 20 | No combo boards are recorded and the effect does not add bodies or build a board (verified from text; observed absence in combos). |
| Resource Economy | 25 | Banishes itself from the graveyard as its cost for a single stop, with no draw, search, or recovery (verified from text). |
| Effect & Interaction | 58 | Ends the opponent's Battle Phase at instant speed, a strong stop against attack-based turns but limited to one use per Duel (verified from text, inferred strength). |
| Material Utility | 45 | A Level 4 LIGHT Machine that can be used as a generic material, but the text gives no material-specific value and the body is 1800 DEF (verified from stats, inferred use). |
| Resilience & Flexibility | 45 | Its one-shot graveyard effect can be answered by the opponent in response and is unusable once spent (verified from text, inferred). |
| Deck-Building Efficiency | 85 | A single-copy slot with no garnet, brick, or self-lock restriction, and 394 of 400 sampled decks run exactly one copy (observed, verified copy distribution). |
Calculation
Weight profile: Board breaker / Going-second profile, primary role only (no secondary blend applied). Intrinsic ≈ 56, Deck ≈ 54, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Cheap single-copy slot that is run widely across many archetypes
- Instant-speed Battle Phase stop that punishes attack-based turns
- Level 4 LIGHT Machine body that can still serve as generic material after use
Weaknesses
- Only works from the graveyard, so it is dead in hand or on the field until sent there
- Once per Duel, so it is a single answer rather than a repeatable interaction
- Adds no board, card advantage, or combo value on its own
Counters / choke points
- Opponents who do not enter the Battle Phase or who attack in Main Phase 1 give the effect no window to act
- Removing the card from the graveyard before the Battle Phase, where the rules allow it, denies the cost
Best use
Battle Phase stopper / one-shot graveyard interaction. Decks: Cyber Dragon, Lightsworn, Dark Magician, Cyberdark, Galaxy Photon, Diabellstar. Suggested copies: 1.
Evidence & gaps
- Verified: Quick Effect, once per Duel: banish from GY to end the opponent's Battle Phase; Level 4 LIGHT Machine Effect Monster, DEF 1800, ATK 0; Legal in TCG, OCG and MasterDuel; Copy distribution: 394 of 400 decks run 1 copy, 6 run 2
- Observed: Present in all 400 sampled decks across 74 archetypes, with 86.5% in gameplay type 7; Top partners include Called by the Grave (64.2%) and Harpie's Feather Duster (63.5%); No combo boards recorded for this card
- Inferred: Primary role is a Battle Phase stopper, so the Board breaker / Going-second profile applies; Real accessibility depends on the card reaching the graveyard, which the evidence does not quantify; Strength is situational and limited to one use per Duel
- Data gaps: no combos supplied, so combo conversion and starter/material shares are text-only inference no guides supplied deck data shows the card in all 400 of 400 sampled decks, which looks anomalous and may reflect a sampling artifact; treated as weak signal usage statistics lists one archetype (Spellbook, 100% inclusion) that does not match the deck archetypes, so the sample is likely very small no banlist token; assumed 3 copies (unlimited) no rulings supplied for the Battle Phase timing interaction
