Apply the following effect, 3 times, in sequence. ● Each player reveals 1 monster from their Deck that does not have ? ATK. Add the monster with the higher ATK to the hand of the player that revealed it, also destroy the monster with the lower ATK and inflict 500 damage to the player that revealed it. If tied, shuffle those monsters into the Decks. For the rest of this turn, neither player can activate the effects of monsters with any of their revealed monsters' names. You can only activate 1 "Subspace Battle" per turn.

Why it scores here
Subspace Battle reliably converts a deck's monster density into hand monsters: each activation can return the higher-ATK revealed monster to its owner's hand, at the cost of a destroyed monster and 500 damage when the revealer loses. It is a 3-copy staple in 400 of 400 sampled decks, so its accessibility and deckbuilding cost score well, but the observed board conversion is thin (2 combos, both starter with no board or end-board) and it is a non-body Spell, so its high inclusion does not buy power. Its strength is breadth across 114 archetypes, not a single powerful line.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 78 | Running in 400/400 sampled decks at an average of 2.57 copies, and starter in 2/2 recorded combos, so it is live in hand in most spots (observed). |
| Combo & Conversion | 35 | Its effect turns one revealed monster into a hand monster, and the recorded combos show no board or end-board output (average power index 26) (observed). |
| Resource Economy | 50 | Each activation is roughly symmetric: the revealer gains the higher-ATK monster and loses the lower one with 500 damage, so net advantage is about even (inferred from text). |
| Effect & Interaction | 30 | It adds only a symmetric per-turn lock on monster effects for both players, and it has no targeted disruption or negation (verified from text). |
| Material Utility | 5 | It is a Spell with no body, so it provides no material or level value (verified from card type). |
| Resilience & Flexibility | 40 | It is a once-per-turn Spell with no backup or recursion, so one negate ends its activation for that turn (inferred from text). |
| Deck-Building Efficiency | 80 | It is a 3-copy staple with no garnet or lock on the rest of the deck, and it needs only monsters the deck already runs (observed from decks, verified from text). |
Calculation
Weight profile: 0.7 Searcher/Tutor + 0.3 Starter. Intrinsic ≈ 56, Deck ≈ 59, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Live in 400/400 sampled decks across 114 archetypes, so it fits almost any monster-heavy build
- Cheap to run at 3 copies with no garnet or self-lock beyond once-per-turn
- Conditional search converts the deck's highest-ATK monster into hand value each activation
Weaknesses
- Thin board conversion: no board or end-board output in the recorded combos
- Symmetric risk: a lower-ATK revealed monster is destroyed and the revealer takes 500 damage
- A non-body Spell with no material value and a once-per-turn limit
Counters / choke points
- Spell negation: a once-per-turn Spell can be stopped by one negate, which ends that turn's activation (inferred from card type)
Best use
Searcher/Tutor (conditional monster-to-hand). Decks: Malefic, Enneacraft, Ryu-Ge, Diabellstar. Suggested copies: 3.
Evidence & gaps
- Verified: Card text: 3 sequential applications, monster reveal and ATK comparison, 500 damage, shuffle on tie, once-per-turn activation, and the revealed-name effect lock; Card type: Spell with no body or material value
- Observed: Included in 400/400 sampled decks, average 2.57 copies, 114 distinct archetypes; 2 of 2 recorded combos show it as starter and end-hand piece, average power index 26, no boards; Usage statistics show 100% inclusion in several archetypes at 2-3 copies
- Inferred: Net card advantage is roughly symmetric per activation; Once-per-turn Spell is negated by one spell negate
- Data gaps: No banlist token; assumed 3 copies (unlimited) Only 2 recorded combos, so combo conversion rests on a thin sample Guide evidence is one general mention that calls the deck non-meta, with no card-specific ruling
