Why it scores here
Tannhauser Gate is a generic Normal Spell that converts two same-Type monsters with 1000 or less ATK into a pair of matching Levels equal to their combined total, unlocking Xyz Ranks that the board could not otherwise reach. Its accessibility is poor because it does nothing from an empty or mismatched board and has no archetype or generic searcher route, and it is a pure minus-one with zero interaction against the opponent. It still earns real points for being fully generic (no archetype lock) and for appearing in 14 decks across 10 distinct archetypes at only 1.14 copies, which confirms it is a cheap, splashable enabler rather than a brick. Its 0 ATK and lack of stats are irrelevant here — nothing in the score comes from ATK, DEF, rarity, or view count.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 30 | No archetype and no searchable route: it is drawn blind and only live once two same-Type monsters with 1000 or less ATK are already on board (verified from card text). |
| Combo & Conversion | 35 | Text converts a two-monster board into a Rank equal to the summed Levels, but combo data shows 0 appearances and 0 starter role, so the payoff is text-only inference (inferred). |
| Resource Economy | 28 | Using the Spell is a straight minus-one with no search, draw, or GY refuel attached to the effect (verified from card text). |
| Effect & Interaction | 5 | The effect only changes Levels of your own monsters and provides no disruption, negation, or removal against the opponent (verified from card text). |
| Material Utility | 40 | Its entire function is to make two existing monsters usable as matching Xyz materials by normalizing their Levels, so it boosts material conversion rather than supplying a body itself (inferred). |
| Resilience & Flexibility | 28 | A single Spell/Trap negation or a missing pair of valid targets blanks it, and nothing recurs it from the GY or re-uses it across turns (verified from card text). |
| Deck-Building Efficiency | 55 | Observed at avg 1.14 copies (12 decks at 1, 2 decks at 2) and 14 main-deck appearances across 10 archetypes, so it is a low-slot generic tech, though it demands small same-Type bodies (observed). |
Calculation
Weight profile: 0.7 Combo enabler + 0.3 Utility. Intrinsic ≈ 42.7, Deck ≈ 41.4, Meta = provisional. Modifiers: Narrow activation requirement (-4); Compact one-off tech (1). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Fully generic Normal Spell with no archetype lock, confirmed by 14 main-deck appearances across 10 distinct archetypes
- Normalizes the Levels of two monsters into a single matching value, enabling Xyz Ranks unreachable from the original Levels
- Level change is permanent and applies to both targeted monsters, so the board stays usable after resolution
- Cheap to run: avg 1.14 copies, 12 of 14 decks use only a single copy
Weaknesses
- Requires two monsters you already control of the same Type with 1000 or less ATK — it is not a starter and does nothing on an empty board
- Pure minus-one: no search, draw, recursion, or card advantage attached
- Provides no interaction with the opponent's plays
- No recorded combos, so its practical ceiling is unmeasured and rests on text inference
- No archetype or generic searcher route, so it is drawn blind
Counters / choke points
- Spell/Trap negation such as Solemn Judgment or any generic Spell negate
- Removing either targeted monster before resolution so the intended Rank cannot be assembled
- Disruption that prevents the two small same-Type monsters from ever coexisting on board
Best use
Generic Level-manipulation enabler for Xyz summons of combined Ranks. Decks: Egyptian God, Train, Deep-Space Cruiser IX / Level-1 engine decks, Black Luster Soldier, Mimighoul. Suggested copies: 1.
Evidence & gaps
- Verified: Card text: target 2 monsters you control of the same Type with 1000 or less ATK; both monsters' Levels become the combined Levels of those 2 monsters; Card is a Normal Spell with no archetype, 0 ATK / 0 DEF, listed in TCG, OCG, MasterDuel and DuelLinks; The effect grants no card advantage and no opponent-facing removal or negation
- Observed: 14 decks run it, all in the main deck, avg 1.14 copies (12 decks at 1 copy, 2 decks at 2 copies); Spread across 10 distinct archetypes, most frequently Egyptian God (4 decks, 28.6%) and Train (2 decks, 14.3%); Top observed partners: One for One (64.3%), Foolish Burial (50%), Deep-Space Cruiser IX (42.9%), Gustav Max (35.7%); combo data contains 0 appearances, so starter role / material role / payoff role are all 0%
- Inferred: Because both monsters take the combined Level, the card converts a two-monster board into an Xyz of that combined Rank; It is not a starter: with no field it is dead, so its accessibility depends on already having two qualifying small same-Type bodies; Its main risk is losing a target to removal during the chain window, which would prevent the intended Rank; The 10-archetype spread suggests it functions as a portable tech card rather than an archetype engine piece
- 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 average power index or average starter count when present, so DeckSynergy and DeckResilience rest on deck counts alone
