While you have no cards in your Extra Deck and you are the only player that controls a Tribute Summoned monster, your opponent cannot Special Summon monsters from the Extra Deck. If a Tribute Summoned monster you control attacks an opponent's monster, it gains 800 ATK during damage calculation only. Once per turn: You can reduce the Level of 1 monster with 2800 ATK and 1000 DEF in your hand by 2 until the end of this turn (even after they are Summoned/Set, and even if this card leaves the field).

Final Score: 49 ± 8 · Confidence: Medium
- Intrinsic: 46.5 · Deck: 50.6 · Meta: provisional
- Primary role: Floodgate/Control · Secondary: Extender
Why it scores here
The card's power is conditional. Its summon lock only applies while you have no Extra Deck cards and you are the only player controlling a Tribute Summoned monster, and its level-reduction effect is a narrow, once-per-turn enabler for one hand monster. Deck evidence is broad (400 decks, 24 archetypes, 135 decks at 3 copies) and confirms the card is a reliable staple, not that it is intrinsically strong. The 2800 ATK / 1000 DEF condition and the card's general reputation earned no points; the score comes from the field's conditional lock and the broad deck adoption.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 60 | Played in 400 of 400 sampled decks at an average of 1.72 copies, mostly in Monarch and True Draco shells, but no searcher or starter evidence is supplied (observed, with inference on routes). |
| Combo & Conversion | 35 | The level reduction converts one hand monster into a lower-level body, but no combo boards are recorded, so conversion is text-only (inferred). |
| Resource Economy | 20 | The text gives no draw, refuel, or card advantage, and the level reduction costs the monster's level rather than a card (verified). |
| Effect & Interaction | 35 | The summon lock only restricts opponent Extra Deck Special Summons while two strict conditions hold, which is situational soft interaction (verified). |
| Material Utility | 30 | The card is a Field Spell and is not a material body; its only material-adjacent effect is the level change on a hand monster (verified text, inferred use). |
| Resilience & Flexibility | 45 | The once-per-turn effect is stated to work even if the card leaves the field, which adds some redundancy, but the lock itself is lost when the field is removed (verified text, inferred). |
| Deck-Building Efficiency | 60 | Run at 1 to 3 copies with no garnet or lock restriction and wide archetype spread, so slot cost is modest (observed). |
Calculation
Weight profile: 0.7 Floodgate/Control + 0.3 Extender. Intrinsic ≈ 46.5, Deck ≈ 50.6, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Broad adoption across 24 archetypes, showing the card is a reliable staple rather than a niche pick
- Field-based lock stays active across turns while its conditions hold
- Once-per-turn level reduction works on a hand monster and is not tied to the card staying on the field
Weaknesses
- Summon lock requires an empty Extra Deck and a single Tribute Summoned monster, which is narrow
- No card advantage or refuel
- Combo evidence is absent, so conversion value is unproven in real boards
Counters / choke points
- Removal or destruction of the Field Spell ends the lock (inferred)
- Opponent controlling their own Tribute Summoned monster disables the lock condition (verified text)
Best use
Floodgate / conditional Extra Deck lock with a level-reduction enabler. Decks: Monarch, True Draco, Morganite.
Evidence & gaps
- Verified: Effect text: Extra Deck Special Summon lock with two conditions; Effect text: +800 ATK during damage calculation for attacking Tribute Summoned monster; Effect text: once-per-turn Level reduction by 2 on a 2800 ATK / 1000 DEF hand monster
- Observed: Present in 400 of 400 sampled decks; 1.72 average copies; 135 decks at 3 copies; Spread across 24 archetypes; 89.2% in gameplay type 7; Top partner The Monarchs Erupt in 76.2% of decks; Usage statistics: Morganite 66.7% inclusion, Monarch 57.1% inclusion
- Inferred: Level reduction is a hand-based enabler that converts a body into a lower-level material or summon; Lock value depends on the board state and is weak when the opponent controls their own Tribute Summoned monster
- Data gaps: No combos supplied, so combo conversion is text-only inference No banlist token; assumed 3 copies (unlimited) No searcher or starter evidence for accessibility Timing of 'even if this card leaves the field' is not confirmed by rulings
