Target 1 Link Monster you control; Special Summon 1 Beast, Beast-Warrior, or Winged Beast monster with a different Type from your hand or GY. If you control at least 1 each of Beast, Beast-Warrior, and Winged Beast monsters: You can banish this card from your GY, then target 1 face-up Spell/Trap your opponent controls; negate its effects until the end of this turn. You can only use 1 "Tri-Brigade Oath" effect per turn, and only once that turn.
Tri-Brigade Oath — Power Evaluation
Final Score: 43 ± 8 · Confidence: Medium
- Intrinsic: 42 · Deck: 43 · Meta: provisional
- Primary role: Extender · Secondary: Removal/Negation
Why it scores here
Tri-Brigade Oath converts a Trap in hand or the GY into one Beast, Beast-Warrior or Winged Beast monster of a different Type, but only while you control a Link monster. Its negation is a once-per-turn effect on a face-up Spell/Trap, and it needs all three Beast-family types present plus a GY banish, so it is conditional and soft. It has no ATK, DEF or material value, so those stats earn nothing. The 400/400 deck presence reflects how this sample was assembled and is not counted as strength.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 45 | The card is a Trap with no stated hand-activation clause, so it depends on being set and surviving a turn (inferred from the Trap frame); the decks show it running at 1.01 copies on average, but the 400-deck sample looks selected around this card (verified text; observed deck stats; inferred timing). |
| Combo & Conversion | 45 | One Beast-family body per activation from hand or GY, gated on a Link monster you control, with no combo boards in the evidence to confirm a larger line (verified text; combo data is empty, so this is text-only inference). |
| Resource Economy | 48 | Trap for a single monster is roughly card-neutral, and the GY banish for the negation is a cost rather than a refuel (verified text; inferred). |
| Effect & Interaction | 35 | The negation is limited to face-up Spell/Traps, needs all three Beast-family types, is once per turn and lasts only until end of turn, so it is soft interaction (verified text). |
| Material Utility | 0 | A Trap is not a monster and cannot be used as material; its only GY use is as a banish cost (verified frame and race fields). |
| Resilience & Flexibility | 40 | It is a single trap that can be negated in hand or set, and the GY banish gives a second use, but there is no redundancy (verified text; inferred). |
| Deck-Building Efficiency | 55 | It is a one-copy slot with no garnet or lock, but it requires a Link monster and Beast-family monsters, which is a mild restriction (verified text; observed copies per deck). |
Calculation
Weight profile: 0.7 Extender + 0.3 Removal/Negation. Intrinsic ≈ 42, Deck ≈ 43, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Converts a single trap into a Beast-family body from hand or GY without spending a monster
- Needs one copy only (observed avg 1.01 copies per deck), so it is cheap to run
- Negation is a second, independent use from the GY
Weaknesses
- Trap timing: needs to be set and survive a turn, which is a tempo cost
- Requires a Link monster you control and three distinct Beast-family types for the negation
- Negation is once per turn, shared across all Tri-Brigade Oath effects, and only hits Spell/Traps
- No material value: the card cannot contribute to Link or Xyz summons
Counters / choke points
- Hand traps that negate it while it is in hand or set (inferred from the Trap frame; no rulings in the evidence)
- Opponent Link or board disruption that removes the Link monster the effect needs (inferred from the target clause)
Best use
Extender. Decks: Tri-Brigade, Yummy, Radiant Typhoon. Suggested copies: 1.
Evidence & gaps
- Verified: Effect text: Link-monster target, Beast-family SS from hand or GY, conditional GY-banish negate, once-per-turn shared clause; Race Normal and frame trap (no ATK/DEF/material value); Copies per deck avg 1.01 across 400 decks
- Observed: Archetype spread: Tri-Brigade 135, Yummy 45, Radiant Typhoon 36 decks; Guide notes Spell/Trap use by these engine lines is rare, consistent with a support role
- Inferred: Trap set-turn timing applies (from the Trap frame, not stated in text); Extender-primary, Negation-secondary role blend; Deck presence reflects a sample selected around this card rather than measured inclusion
- Data gaps: No combos supplied, so combo conversion is text-only inference 400/400 deck presence looks selected around this card; true inclusion rate is not measured usage statistics has a single Bujin row (100%) that contradicts the deck sample and was discounted No rulings or timing clause in the text for the Trap's activation window No banlist token; assumed 3 copies (unlimited) Only one guide mention; it is thin context
