Grand Convergence — Power Evaluation
Final Score: 47 ± 8 · Confidence: Medium
- Intrinsic: 50.5 · Deck: 44.8 · Meta: provisional
- Primary role: Board breaker · Secondary: Removal
Why it scores here
Grand Convergence is a one-card mass destruction effect (all monsters on the field) with 300 damage, but it only resolves while you control Macro Cosmos, which is the card's real access gate. The decks evidence shows Macro Cosmos in 7 of 7 decks, so the line is consistently built around it, yet no combo boards are recorded, so the card's conversion value is text-only. Its high effect score comes from the wipe itself; the symmetric destruction of your own monsters and the field-state requirement pull the total down. Its usage data reflects consistent inclusion alongside Macro Cosmos rather than intrinsic strength.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 35 | Live only with Macro Cosmos on the field; Macro Cosmos is a partner in 7/7 decks (100%), but no combo starter or searched data exists (inferred, observed). |
| Combo & Conversion | 45 | The text converts one card into a full board wipe plus 300 damage, but there are 0 recorded combo appearances, so conversion is text-only (inferred). |
| Resource Economy | 40 | One card for the whole field with no recorded refuel or advantage, and the wipe also clears the player's own monsters (verified text, inferred). |
| Effect & Interaction | 65 | Strong, flexible mass destruction usable as a response on the opponent's turn, though conditional on Macro Cosmos (verified text, observed in 7 decks). |
| Material Utility | 5 | A Quick-Play Spell has no body and cannot be used as material (verified card type). |
| Resilience & Flexibility | 35 | Depends on a single field-state condition (Macro Cosmos) that can be negated or removed, and no redundant access route is evidenced (inferred). |
| Deck-Building Efficiency | 40 | Needs Macro Cosmos in the deck, and the typical 3 copies become dead without it; the field requirement restricts deck construction (observed in decks, inferred). |
Calculation
Weight profile: 0.7 Board breaker + 0.3 Removal. Intrinsic ≈ 50.5, Deck ≈ 44.8, Meta = provisional. Modifiers: Field-state restriction (-3). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Full-field mass destruction plus 300 damage from one Quick-Play Spell
- Used as a response, so it can punish an opponent's board on their turn
- Consistently played alongside Macro Cosmos in 7 of 7 sampled decks
Weaknesses
- Requires Macro Cosmos on the field; without it the card is dead
- Destroys all monsters, including your own
- No combo, starter, or searched data to show it converts beyond the wipe
Counters / choke points
- Negating or destroying Macro Cosmos removes the activation condition (inferred from the text)
- Interaction that stops Quick-Play activations on the opponent's turn (inferred)
Best use
Board breaker / reset response when the opponent has built a board and Macro Cosmos is already live. Decks: Macro Cosmos-based lines seen in the sample (Metaphys, Barrier Statue, Psy-Frame, Myutant, Cancer, Ritual Beast). Suggested copies: 3.
Evidence & gaps
- Verified: Text: if you control Macro Cosmos, inflict 300 damage to the opponent and destroy all monsters on the field; Card type: Quick-Play Spell with no body; Macro Cosmos appears in 7 of 7 sampled decks
- Observed: Average 2.43 copies per deck (max 3), 5 main-deck Gameplay type 7 decks and 2 type 4 decks; Usage statistics: 100% inclusion in Metaphys with typical 3 copies
- Inferred: Accessibility and deckbuilding cost follow from the Macro Cosmos field requirement; Symmetric wipe lowers resource economy; Counterplay via negating Macro Cosmos
- Data gaps: No combos supplied, so combo conversion is text-only inference No guides supplied No rulings supplied No banlist token, so 3 copies assumed (unlimited) Macro Cosmos's own card text is not in the evidence pack
