1 Beast-Type Tuner + 1 or more non-Tuner monsters Once per turn, during your Main Phase, you can select 1 face-up monster your opponent controls.

Why it scores here
Thunder Unicorn is a Level 5 Synchro that converts a Tuner plus non-Tuner base into one 2200 ATK body. Its real value is a once-per-turn Main Phase effect that cuts one opponent monster's ATK by 500 for each monster you control, plus a turn-long lock on other attackers. That is soft board-breaking, not a clean removal or negation. The 2200 ATK and 1800 DEF earn no points on their own, and the 27-deck sample only confirms it is consistently run at about one copy across 12 archetypes; it does not raise the score. Combo data is absent, so conversion is text-only and the score stays in the mid range.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 60 | Run in 27 of the sampled decks across 12 archetypes at an average of 1.11 copies, with staple partners such as Monster Reborn and One for One (observed; the Synchro route itself is verified from text). |
| Combo & Conversion | 40 | No recorded boards exist, so the one-card-to-full-board conversion is inferred only from text: one body plus a debuff (inferred). |
| Resource Economy | 30 | No card advantage, draw, or recursion appears in the text, so the card is roughly even at best (verified from text). |
| Effect & Interaction | 55 | Its once-per-turn ATK reduction scales with monsters you control and is paired with an attack lock on other monsters, giving soft interaction in the Main Phase only (verified from text; the scaling is an inference about impact). |
| Material Utility | 45 | Usable as a Level 5 LIGHT Beast body, but no material-use evidence was supplied, so the value of its body after the effect is negated stays inferred. |
| Resilience & Flexibility | 40 | The effect is once per turn and Main-Phase only, and the card has no second zone or turn of value, so one response can stop it (inferred from text). |
| Deck-Building Efficiency | 70 | Typically runs as a single copy with no garnet, lock, or floodgate cost; the Tuner plus non-Tuner requirement is the only restriction (verified from deck copy counts and text). |
Calculation
Weight profile: 0.7 Board breaker + 0.3 Boss/End-board. Intrinsic ≈ 56, Deck ≈ 54, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Consistent single-copy inclusion across 12 archetypes and 3 gameplay types
- Main-Phase ATK reduction that scales with the controller's board, plus an attack lock on other monsters
- Cheap to run, with no garnets or locks in its requirements
Weaknesses
- Once per turn and Main-Phase only, so it cannot act as a response
- No card advantage or recursion
- No recorded combo evidence showing it converts into a full board
Counters / choke points
- Any response that stops the Synchro Summon or removes the target before the effect resolves (inferred from the once-per-turn, Main-Phase timing; no specific counter cards are in the evidence)
Best use
Board breaker that shrinks a single opposing monster and locks other attackers for a turn. Decks: Synchro-based decks that run Monster Reborn and One for One alongside it. Suggested copies: 1.
Evidence & gaps
- Verified: Effect text: once-per-turn Main Phase ATK reduction of 500 per monster you control, plus a turn-long attack lock on other monsters; 27 sampled decks, average 1.11 copies, 12 distinct archetypes, 3 gameplay types; Synchro requirement: one Beast-Type Tuner plus one or more non-Tuner monsters
- Observed: Top partners (Monster Reborn 81.5%, One for One 77.8%) co-occur in the sampled decks but are generic staples, so they do not show power by themselves
- Inferred: The ATK reduction makes it a board breaker, not a removal card; Its body still provides a Level 5 LIGHT Beast material after the effect is negated
- Data gaps: no combos supplied — combo conversion is text-only inference no guides supplied no banlist token — assumed 3 copies (unlimited) no usage statistics (StatisticsCard) — archetype inclusion % inferred from deck sample only no starter-count data — deck resilience is inferred from archetype spread alone no material-use data — material utility is inferred from text
