Why it scores here
Earthshattering Event is a conditional Continuous Spell: whenever a card is sent from a Deck to the Graveyard, it can shuffle one Graveyard card from either player back into its Deck and stops any Deck-to-Graveyard sends for the rest of the turn. Its value is situational GY control and a turn-wide lock on Deck-to-GY engines, not board-building or card advantage. The 26-deck sample (11 archetypes, mostly 1 copy) confirms it is a realistic, low-cost sideboard-style staple across homes, but there are no combo records, so its power is text-inferred. High ATK-independent stats or deck count did not earn points beyond what the interaction and deck-cost axes support.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 45 | 26 of the 26 sampled decks run it in the main deck at an average of 1.46 copies, so it is reliably included, but it has no searcher or starter data to show it is drawn on time (observed; the combo starter count is 0). |
| Combo & Conversion | 25 | No recorded boards, so no structural conversion data exists; the text only shuffles a single Graveyard card and builds no board (verified from text; no combo evidence). |
| Resource Economy | 40 | It returns one Graveyard card to the Deck with no draw, search or summon, so it is roughly card-neutral and exchanges one card for one card (inference from text). |
| Effect & Interaction | 50 | It answers Graveyard resources for both players and locks Deck-to-GY sends for the turn, a soft and conditional interaction whose trigger depends on a prior Deck-to-GY event (verified from text, inferred for timing). |
| Material Utility | 5 | It is a Spell with no material body, so it contributes nothing as material (verified from card type). |
| Resilience & Flexibility | 40 | As a face-up Continuous Spell it is removed by a single destruction or bounce effect, and the trigger needs a Deck-to-GY event each time, which limits it to certain turns (inferred from text; the 11-archetype spread is observed). |
| Deck-Building Efficiency | 60 | It is a single-copy, non-garnet Spell that is cheap to run, though its turn-wide lock also restricts the player's own Deck-to-GY effects, a mild self-restriction (verified from text, inferred for the self-lock). |
Calculation
Weight profile: 0.7 Floodgate/Control + 0.3 Recovery/Recursion. Intrinsic ≈ 48.9, Deck ≈ 47.6, Meta = provisional. Modifiers: Self-restriction (-2). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Broad utility across 11 archetypes, so it is not tied to one home
- Cheap single-copy slot with no garnet or lock on deck building
- Hits Graveyard resources from either player, including opponent recursion
- Turn-wide Deck-to-GY lock shuts down Deck-to-GY engines for the rest of the turn
Weaknesses
- The trigger requires a prior Deck-to-GY event, so it is dead in many spots
- No draw, search or summon, so it does not generate board or advantage on its own
- A face-up Continuous Spell is removed by a single destruction or bounce
- No combo data, so conversion value is text-inferred only
Counters / choke points
- Graveyard-free or GY-light decks that never send cards Deck-to-GY
- Continuous Spell removal or bounce effects
- Opponent plays that avoid Deck-to-GY sends
Best use
Situational GY control and Deck-to-GY lock in a fair-to-control shell; a single-copy flex staple. Decks: Sự kiện Limit 1, Relinquished, Millennium, Gate Guardian, Dark Magician, Galaxy-Eyes, Mathmech, @Ignister. Suggested copies: 1.
Evidence & gaps
- Verified: Card text: conditional on a Deck-to-GY send, targets one card in either Graveyard, shuffles it into the Deck, and stops Deck-to-GY sends for the turn; Card type is a Continuous Spell with no ATK, DEF, or material value; Present in 26 of 26 sampled decks at 1.46 average copies, max 3; Spread across 11 distinct archetypes and 3 gameplay types
- Observed: Top partners include Harpie's Feather Duster (17 co-decks), Monster Reborn (13), and Dark Magician (12); Gameplay split is 50% type 7, 30.8% type 4, and 19.2% type 6
- Inferred: The lock is mostly a conditional GY-control tool, with its value depending on opponent Deck-to-GY plays; Its turn-wide lock also restricts the controller's own Deck-to-GY effects; Resource value is roughly neutral because it recycles one card without drawing
- 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 % is inferred from the deck sample only
