Each turn, 1 Level 5 or higher Gemini monster you Normal Summon can be Summoned without Tributing. During your Main Phase, you can Normal Summon 1 Gemini monster in addition to your Normal Summon/Set. (You can only gain this effect once per turn.) Once per turn: You can target 1 card your opponent controls; banish 1 Gemini monster you control, that is treated as an Effect Monster and has gained its effects, until your opponent's End Phase, and if you do, destroy that card.
Catalyst Field — Power Evaluation
Final Score: 46 ± 8 · Confidence: Medium
- Intrinsic: 48.3 · Deck: 45.3 · Meta: provisional
- Primary role: Extender · Secondary: Removal
Why it scores here
Catalyst Field gives a Gemini board extra Normal Summons and tribute-free Summons of Level 5+ Gemini, and its once-per-turn removal costs a Gemini body, so it converts a Gemini board into tempo and one targeted destroy rather than card advantage. Its 43-deck presence (15 Geminis, 14 Dual Avatar) confirms it is a reliable staple of its home, not that it is intrinsically strong; that frequency did not inflate the score. No combo data was supplied, so combo conversion rests on card text alone, and the attached guide does not name this card.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 60 | Live in 43 of 43 sampled decks at 1.77 copies on average, and the guide describes Golknight enabling Gemini Spell/Trap searches, which may reach this card (observed deck frequency; search route inferred). |
| Combo & Conversion | 50 | The text enables extra Summons and a targeted destroy, but no recorded boards show what it builds from a realistic start (inferred from text; no combo data). |
| Resource Economy | 35 | No draw, search or recursion; the banish-to-destroy cost trades a Gemini body for one card, so it is roughly even at best (verified from text). |
| Effect & Interaction | 55 | Once-per-turn targeted destroy of an opponent card until the opponent's End Phase, paid by banishing a Gemini you control (verified from text). |
| Material Utility | 25 | A Field Spell with no material or level-provider role of its own; it does not convert into material when blanked (verified from text). |
| Resilience & Flexibility | 40 | A single field-zone card that the opponent can remove or negate in response, and its effect is lost if the field is taken (inferred from text). |
| Deck-Building Efficiency | 60 | One slot, no garnets or locks, and copies are flexible at 1 to 3 (observed in decks), but it is restricted to Gemini-based decks (observed; self-restriction modifier applied). |
Calculation
Weight profile: 0.7 Extender + 0.3 Removal/Negation. Intrinsic ≈ 48.3, Deck ≈ 45.3, Meta = provisional. Modifiers: Gemini-locked self-restriction (-3). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Enables extra Normal Summons and tribute-free Summons of Level 5+ Gemini, which the Gemini home relies on
- Targeted once-per-turn destroy paid by a Gemini body, with real presence in 43 sampled decks
- Single slot with no garnets and flexible copy counts
Weaknesses
- No card advantage or recursion; the destroy costs a Gemini body
- Gemini-only restriction limits it to one archetype family
- Removal is conditional on a banishable Gemini being on the board
- No recorded combo data to confirm how far it converts
Counters / choke points
- Opponent negation of the activated effect in response (inferred from text)
- Opponent removal or field-destruction effects that take the card out of the Field Zone (inferred from text)
Best use
Extender with a once-per-turn removal option, supporting the Gemini board. Decks: Geminis, Dual Avatar.
Evidence & gaps
- Verified: Field Spell restricted to Gemini monsters; Level 5+ Gemini you Normal Summon can be Summoned without Tributing, once per turn; Extra Normal Summon of 1 Gemini in the Main Phase, once per turn; Once-per-turn: target 1 opponent card and banish 1 Gemini you control to destroy it, until the opponent's End Phase
- Observed: Present in 43 of 43 sampled decks, 1.77 copies on average (max 3); Most common in the Geminis (15 decks) and Dual Avatar (14 decks) archetypes; Frequent partners include Gemini Ablation (79.1%) and Supervise (74.4%)
- Inferred: The Golknight Gemini Spell/Trap search route may reach this card, since the guide names it for Gemini spells and traps generally; Its removal and summon boosts convert a Gemini board into tempo rather than card advantage
- Data gaps: No combo data was supplied, so combo conversion is text-only inference The guide snippet does not name Catalyst Field, and this card's passcode is absent from the guide section's co-card list No banlist token was supplied; unlimited copies assumed No usage statistics (StatisticsCard) available; inclusion is from the deck sample only No rulings supplied for the banish-treated-as-effect-monster interaction
