Duel Tower — Power Evaluation
Final Score: 54 ± 8 · Confidence: Medium
- Intrinsic: 54.5 · Deck: 53.5 · Meta: provisional
- Primary role: Board breaker · Secondary: Extender
Why it scores here
Duel Tower scores mid-range. Its value is a delayed, symmetrical field wipe (destroy all cards on the field, active one End Phase after activation) plus a Battle Phase trigger that banishes a deck monster and lets the higher-ATK revealer Special Summon from hand. Its presence in 112 of 112 sampled decks was used only to confirm it is practically playable, not to raise the score. High ATK and popularity earned nothing, and the absence of combo data keeps combo conversion at a text-only inference.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 60 | Appears in 112 of 112 sampled decks at an average of 1.2 copies, so access is reliable, but no searcher or starter counts were supplied (observed). |
| Combo & Conversion | 40 | The text describes a delayed mass-destruction effect and a Battle Phase summon trigger, but no combo boards were supplied to confirm a conversion line (inferred). |
| Resource Economy | 50 | Each Battle Phase reveal banishes a deck monster to enable a hand summon, a board-for-deck trade with no clear net card advantage (inferred). |
| Effect & Interaction | 60 | The destroy-all-field effect is strong but symmetrical, takes a full turn to resolve, and also destroys the controller's own cards (verified). |
| Material Utility | 5 | It is a Spell card with no level, attribute, or material value, so it provides no material body (verified). |
| Resilience & Flexibility | 45 | It must stay on the field through a full turn to resolve, so it is exposed to field-spell removal and disruption (inferred). |
| Deck-Building Efficiency | 65 | One slot at 1.2 average copies with no garnet or lock clause, and it is listed as legal in TCG, OCG and MasterDuel (verified). |
Calculation
Weight profile: 0.7 Board breaker + 0.3 Extender. Intrinsic ≈ 54.5, Deck ≈ 53.5, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Clears the entire field, including boards the opponent built, in one activation
- Appears in 112 of 112 sampled decks across 15 archetypes, confirming it is reliably playable (observed)
- Battle Phase trigger gives the higher-ATK revealer a free hand summon that can attack directly
Weaknesses
- Destroys the controller's own cards as well as the opponent's
- Must survive to the next End Phase, giving the opponent a full turn to answer it
- Each Battle Phase reveal banishes a deck monster, and the opponent benefits when they reveal the higher ATK
- No combo or guide evidence, so real conversion value is unverified
Counters / choke points
- Field-spell removal or destruction effects
- Spell-negation or disruption during the delay window before the End Phase trigger resolves

Evidence & gaps
- Verified: Card text: Battle Phase reveal/banish/summon trigger and once-per-turn End Phase destroy-all-field effect; Type is Spell Card; legal in TCG, OCG and MasterDuel; 112 of 112 sampled decks run it at 1 copy in the majority of cases (avg 1.2)

- Inferred: Primary value is a symmetrical, delayed board wipe; The one-turn delay gives the opponent a window to answer; Battle Phase trigger is a card-for-board trade with no clear net advantage; Field-spell persistence exposes it to removal
- Data gaps: no combos supplied; combo conversion is text-only inference no guides supplied no starter/searcher counts for accessibility no usage statistics (StatisticsCard); inclusion inferred from the 112-deck sample only no rulings supplied for the reveal-tie and End Phase timing the identical 31-deck counts for Hieratic, Galaxy Photon and Blue-Eyes may be a sample artifact no banlist token; assumed 3 copies (unlimited)
