Why it scores here
Half Shut is a quick-play spell that protects one face-up monster from battle destruction and halves its ATK for the turn. It converts into a combat trick rather than a board or a card-advantage engine, so it has no combo, refuel or material value. Its score comes mainly from being a cheap, clean spell that 71 recent decks run at about 2.2 copies, with 63% of them in Numeron. The text alone does not earn points for being a generic card, and the 45 Numeron decks show concentration in one archetype rather than broad power.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 55 | Quick-play spell that can be held in hand and used on the opponent's turn; 71 recent decks run it at 2.23 average copies, but no starter or searched observations exist (inferred). |
| Combo & Conversion | 20 | No recorded combo boards include it, so it builds nothing on its own beyond protecting an existing monster (observed: 0 combos; text-based inference). |
| Resource Economy | 25 | A one-for-one spell with no draw, search or graveyard refuel in its text (verified). |
| Effect & Interaction | 35 | Targeted protection and ATK halving for a single monster, which is situational combat interaction rather than negation or removal (verified text, inferred strength). |
| Material Utility | 10 | It is a spell and cannot be material, so this axis scores only the lack of body value (verified). |
| Resilience & Flexibility | 30 | Works on any face-up monster and only for one turn, but it can be answered by effect removal or negation on the target (inferred). |
| Deck-Building Efficiency | 75 | Three copies of a generic spell cost few slots, and the 1-3 copy spread in decks shows it is easy to run (observed). |
Calculation
Weight profile: Utility default profile (no secondary blend applied). Intrinsic ≈ 45, Deck ≈ 44, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck

Evidence & gaps
- Verified: Quick-Play Spell: target 1 face-up monster, cannot be destroyed by battle this turn, ATK halved until end of turn; 71 recent decks run it, 2.23 average copies, 63.4% Numeron
- Observed: Zero combo appearances in the supplied boards; Top partners are Numeron support and generic staples, not a combo line
- Inferred: Its value is a combat trick, not a combo enabler; Effect negation on the target answers it
- Data gaps: no combos supplied, so combo conversion is text-only inference no guides supplied no banlist token, assumed 3 copies (unlimited) no usage statistics (StatisticsCard), so archetype inclusion is inferred from the deck sample only
