Ice Knight — Power Evaluation
Final Score: 53 ± 6 · Confidence: Medium
- Intrinsic: 54 · Deck: 52 · Meta: provisional
- Primary role: Extender · Secondary: Material body
Why it scores here
Ice Knight is a clean Level 4 WATER Aqua body. Its once-per-turn effect adds one extra Normal Summon of a WATER monster in the Main Phase, which is tempo rather than card advantage. Its ATK gain and the 1300 ATK stat earn nothing on their own. The self-restriction that blocks non-WATER summons for the rest of the turn is scored as a deck-building cost. The 105-deck spread across 27 archetypes confirms accessibility and portability but does not inflate the score, and the absence of combo data keeps the combo axis moderate.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 55 | Present in all 105 sampled decks at about 2.24 copies each across 27 archetypes, but no searcher or starter data is supplied (observed, inferred). |
| Combo & Conversion | 45 | Extra WATER Normal Summon adds one body on the field, but there are zero recorded combo boards to confirm a payoff (verified text, inferred). |
| Resource Economy | 40 | No card advantage or refuel is stated in the text; the benefit is tempo from the extra summon (verified text, inferred). |
| Effect & Interaction | 10 | No negation, removal or opponent interaction in the text; the only restriction hits the controller's own non-WATER summons (verified text). |
| Material Utility | 70 | Level 4 WATER Aqua body is a clean generic material, and the body remains usable even when its effect is negated (verified text, inferred). |
| Resilience & Flexibility | 45 | A single monster on the field with no recovery or redundancy beyond the deck copies; removal or a negate ends the body (inferred). |
| Deck-Building Efficiency | 55 | Low slot cost with a once-per-turn gate, but the self-lock on non-WATER summons is a real restriction on deck composition (verified text, observed). |
Calculation
Weight profile: 0.7 Extender + 0.3 Material body. Intrinsic ≈ 54, Deck ≈ 52, Meta = provisional. Modifiers: Self-locking restriction (-3). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Clean Level 4 WATER Aqua body that serves as generic material (verified text)
- Extra WATER Normal Summon adds Main Phase tempo once per turn (verified text)
- Played in 105 of 105 sampled decks across 27 archetypes at about 2.24 copies (observed)
- Strong recorded partner overlap with Ice Barrier, Harpie's Feather Duster and Stealth Kragen (observed)
Weaknesses
- Self-restriction blocks non-WATER Normal and Special Summons for the rest of the turn (verified text)
- ATK gain is conditional and not a power driver (verified text)
- No combo evidence, so payoff and board conversion stay unconfirmed (data gap)
- As a single monster body it is exposed to removal and negation (inferred)
Counters / choke points
- Monster removal or negation in response to the activation (inferred, speculation)
Best use
Tempo extender and Level 4 WATER material body. Decks: Water-focused Shark, Penguin and Ice Barrier builds (observed). Suggested copies: 2.
Evidence & gaps
- Verified: Level 4 WATER Aqua effect monster, 1300 ATK / 1200 DEF, per card text; Once-per-turn extra WATER Normal Summon in Main Phase, per card text; Self-restriction blocking non-WATER Normal and Special Summons this turn, per card text
- Observed: Present in 105 of 105 sampled decks, 2.24 average copies, 27 archetypes; Top partners Ice Barrier and Harpie's Feather Duster at 52.4 percent co-occurrence; Staple section mention in one guide
- Inferred: Tempo-extender role from the extra summon clause; Material body role from Level 4 WATER attribute; Deck-building cost from the self-lock restriction
- Data gaps: no combos supplied, so combo conversion is text-only inference no banlist token, assumed 3 copies (unlimited) no usage statistics (StatisticsCard), so archetype inclusion is inferred from the deck sample only no rulings supplied for the once-per-turn and summon-restriction interaction
