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
