Brain Control — Power Evaluation
Final Score: 57 ± 6 · Confidence: Medium
- Intrinsic: 58 · Deck: 56 · Meta: provisional
- Primary role: Board breaker · Secondary: Utility
Why it scores here
Brain Control converts one face-up opposing monster that can be Normal Summoned or Set into a temporary body for its controller until the End Phase, paid for with 800 LP. Its inclusion in all 400 sampled decks across 79 archetypes confirms it is a live, cheap, single-slot card, but that frequency does not add points on its own. The score is held down by the absence of any combo data, the 800 LP cost, the Normal-Summon-only target restriction, and the lack of resource gain; the high ATK of a stolen monster earns nothing.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 68 | Spell in hand with no searcher needed and 100% sampled deck inclusion, but the 800 LP cost and a valid target requirement cap it (verified, deck stat; play routes inferred from text). |
| Combo & Conversion | 45 | No recorded combo boards, so conversion is text-only: it steals one monster for a tribute or attack swing, not a full board (inferred). |
| Resource Economy | 40 | A single-card swing with no graveyard refuel or search, and the LP cost offsets any monster gained (inferred from text). |
| Effect & Interaction | 55 | Strong temporary control of an opposing monster, but limited to Normal Summonable or Settable targets and ends at End Phase (verified, card text). |
| Material Utility | 15 | A Spell body has no material, level, or attribute value, so this axis is low by design (verified, card type). |
| Resilience & Flexibility | 40 | No once-per-turn or redundancy; a single spell can be negated and the control effect ends at End Phase (inferred from text). |
| Deck-Building Efficiency | 80 | Typically one copy (avg 1.1), no garnet or lock, and splashable into any deck (verified, deck copy distribution). |
Calculation
Weight profile: 0.7 Board breaker + 0.3 Utility. Intrinsic ≈ 58, Deck ≈ 56, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck (decks present, combos absent, meta unknown)
Strengths
- Removes an opposing Normal-Summonable monster for the turn, usable directly from hand with no searcher.
- Generic and portable: present in 79 distinct archetypes in the sample, typically one copy.
- No garnet, lock, or self-restriction; easy to fit into most decks.
Weaknesses
- Costs 800 LP before the target is chosen.
- Target must be face-up and Normal Summonable or Settable, excluding Special-Summon-only monsters.
- Control ends at the End Phase, so the stolen monster is temporary.
- No combo evidence, so its real conversion rate is unmeasured.
Counters / choke points
- Generic spell negation and monster-removal responses (inferred; no counter data in evidence).
Best use
Temporary monster steal for tribute or attack swing, a one-slot tempo card. Decks: Blackwings, Lightsworn, Monarch. Suggested copies: 1.
Evidence & gaps
- Verified: Card text: pay 800 LP, target one face-up opposing monster that can be Normal Summoned or Set, take control until the End Phase.; Deck evidence: in 400 of 400 sampled decks, avg 1.1 copies, 79 distinct archetypes.; Usage statistics: 100% inclusion in Flamvell and Elemental HERO, 85.7% in Nephthys, 75% in Frog, 62.5% in Blackwings (typical 1 copy).
- Observed: Top partners by co-occurrence: Mystical Space Typhoon 91%, Heavy Storm 85.5%, Mirror Force 82.8%.
- Inferred: Hand-live accessibility with no search needed, but limited by the LP cost and target restriction.; Combo conversion is a one-monster swing (text-only; no board data).; Resilience is limited because it is a single Spell that can be negated and ends at End Phase.
- Data gaps: no combos supplied — combo conversion is text-only inference no guides supplied no banlist token — assumed 3 copies (unlimited) decks_evidence is 400/400 inclusion, which looks like a selection-biased sample; treated as accessibility, not strength usage_statistics covers only 5 archetypes
