Triangle Ecstasy Spark

Triangle Ecstasy Spark — Power Evaluation

Final Score: 47 ± 7 · Confidence: Medium

• Intrinsic: 45 · Deck: 49 · Meta: provisional
• Primary role: Board breaker / Going-second · Secondary: Utility, Removal / Negation

Why it scores here

Triangle Ecstasy Spark converts into one turn of Trap lockdown — the opponent cannot activate Trap Cards and all their on-field Trap effects are negated — which clears a path for an OTK, while also setting any 'Harpie Lady Sisters' already on the field to 2700 ATK. That is a real but narrow interaction: it builds no board, generates no card advantage, and its ATK clause only matters if the specific 'Harpie Lady Sisters' body is already sitting on the field. Because there is no body, no search route to the card itself, and no combo data showing boards it appears in, its score is driven by the trap-lock utility and by how cleanly it slots into Harpie decks — its stats (0 ATK/DEF) and 66-deck popularity earn it nothing.

Axis scores

Calculation

Weight profile: 0.7 Board breaker/Going-second + 0.3 Utility (multi-role blend). Intrinsic ≈ 45, Deck ≈ 49, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

• One-turn blanket Trap lockdown plus negation of all on-field opponent Trap effects, strong for going-second OTK turns.
• Raises 'Harpie Lady Sisters' on the field to 2700 ATK for a damage push.
• No activation cost, no restriction, and it fits the Harpie core cleanly at 1-3 copies.
• Main-decked in 66 of 66 sampled decks, confirming the role is practical, not theoretical.

Weaknesses

• ATK clause applies only to 'Harpie Lady Sisters' already on the field (and only currently on the field).
• The anti-Trap effect lasts a single turn and does nothing against monster or hand-trap interaction.
• No body, no card advantage, no board building — it is a pure tempo/utility slot.
• Dependent on an opponent who has committed Traps to be worth its slot.

Counters / choke points

• Spell/Trap negation that resolves before this card (e.g. Counter Traps chained to its activation) still stops the whole effect.
• Monster-effect negation (Apollousa, Borreload Savage, etc.) can invalidate the Spell without needing a Trap.
• Hand traps and monster-based disruption are entirely unaffected by the Trap-only clause.
• Decks that do not rely on Traps (or that win before the damage step) make the card near-blank.

Evidence & gaps

• Verified: Card text: until end of turn, all 'Harpie Lady Sisters' on the field become 2700 ATK.; Card text: opponent cannot activate Trap Cards, and all opponent's on-field Trap effects are negated.; Card is a Normal Spell, archetype Harpie, legal in TCG, OCG, Master Duel, and Duel Links.
• Observed: 66/66 sampled decks run it in the Main Deck at 1.86 average copies (distribution 33x1, 9x2, 24x3).; 60.6% of those decks are Harpie; top partners are Elegant Egotist (100%), Harpies' Hunting Ground (98.5%), and Harpie Lady Sisters (97%).; 0 combo appearances and 0 guide mentions across the supplied evidence.
• Inferred: Its practical role is a one-turn anti-Trap tempo card that clears a path for an OTK turn.; The ATK clause is dead unless 'Harpie Lady Sisters' is already on the field when it resolves.; The card is archetype-bound and provides no advantage or board development.
• Data gaps: no combos supplied — combo conversion is text-only inference no guides supplied no banlist token — assumed 3 copies (unlimited) no end-board or power-index data to confirm the impact of the resolved effect
