You can only use each effect of "Machina Citadel" once per turn.
Machina Citadel — Power Evaluation
Final Score: 65 ± 5 · Confidence: Medium
- Intrinsic: 64 · Deck: 66 · Meta: provisional
- Primary role: Boss/End-board · Secondary: Board breaker, Recovery/Recursion
Why it scores here
Machina Citadel is a reliably accessible high-ATK boss that integrates cleanly into 51+ distinct archetypes, primarily as a finisher and board-control piece. Its quick-effect removal is flexible and its GY recursion provides strong resilience, making it a solid technical inclusion. However, limited combo evidence showing it as a starter in only 20% of recorded boards, combined with its dependence on other EARTH Machines to fully activate, prevents it from scoring higher. The card delivers steady value across Machina, Train, and Infinitrack strategies but lacks the explosive combo generation or resource acceleration of top-tier bosses.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 60 | Requires special summon setup and appears as starter in only 1 of 5 recorded combos, but searchable via Machina engine and present in 100% of Machina/Crystron/Machines decks (verified from decks_evidence). |
| Combo & Conversion | 48 | Appears in combos with 64.4 average power index but does not feature in end boards and is not listed as payoff or material in the recorded examples, suggesting incidental rather than core combo generation (observed from combos_evidence appearance patterns). |
| Resource Economy | 50 | The quick effect costs a Machine monster but clears opponent's field; the GY recursion returns the card to the field when EARTH Machines die, resulting in roughly neutral card economy (inferred from card text and recursion pattern). |
| Effect & Interaction | 65 | Quick-effect board wipe targeting opponent's monsters with ATK less than or equal to a Machine you control is flexible and plays around most interactive decks, though effectiveness depends on your own field state (verified from effect text). |
| Material Utility | 60 | Level 10 EARTH Machine with 3000 ATK makes it ideal for Rank 10 Xyz summons like Superdreadnoughts (80% co-deck rate with such cards), but evidence shows zero appearances as material in recorded combos (verified from material usage and co-partner stats). |
| Resilience & Flexibility | 68 | GY recursion triggered by destruction of EARTH Machines provides built-in comeback value across multiple turns, though it requires other Machines to be present to activate the effect (verified from card text and decks showing it as primary recursion engine). |
| Deck-Building Efficiency | 70 | Runs at 1.13 copies average with no reported garnet or bricking issues across 400 sampled decks and 51 distinct archetypes, integrating cleanly without deck restrictions (observed from deck statistics and zero garnet signals). |
Calculation
Weight profile: Boss/End-board primary role. Intrinsic ≈ 64, Deck ≈ 66, Meta = provisional. Modifiers: Splashability across archetypes (2). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Strong GY recursion that triggers whenever EARTH Machines you control are destroyed, providing reliable recovery and multi-turn flexibility
- Quick-effect board wipe allows removal of opponent monsters during their turn, enabling reactive board control
- Excellent stats (3000 ATK, Level 10) make it ideal for Rank 10 Xyz summons like Superdreadnoughts (72%+ co-deck rates)
- Seamlessly integrates into 51+ distinct archetypes with highest inclusion in Machina (100%), Earth Machine (100%), Machines (100%), Train (16.2%), and Infinitrack (9.8%)
- Minimal deck construction constraints; runs at 1.13 copies average with no bricking or garnet issues
Weaknesses
- Cannot be Normal Summoned; entirely dependent on special summon enablers that the deck must already support
- Quick-effect board wipe requires sacrificing one of your own Machine monsters, creating a −1 that only breaks even when opponent has larger monsters
- GY recursion only activates when EARTH Machine monsters you control are destroyed; non-functional without other EARTH Machines on field
- Weak combo presence: appears as a starter in only 20% of recorded combos and does not appear in end boards of any recorded combo, suggesting limited combo generation
- High level (10) makes it inaccessible in non-Machine decks lacking special summon support
Counters / choke points
- Graveyard removal (Macro Cosmos, Dimensional Fissure) prevents GY recursion while Citadel is in the yard
- Special summon negation (effect negation, Stardust Charge Warrior) stops both initial summon and GY recursion
- Field wipe before Citadel's summoning window allows opponent to reset board without triggering recursion
Best use
Boss/End-board finisher and reactive board control. Decks: Machina, Earth Machine, Train, Infinitrack, Crystron, R.B..
Evidence & gaps
- Verified: Card text: Cannot be Normal Summoned; must be Special Summoned by card effect; Quick effect destroys 1 Machine you control and all opponent monsters with ATK ≤ it, with once-per-turn limit; GY recursion when face-up EARTH Machine(s) you control (except Citadel) are destroyed by battle or effect; Level 10 EARTH Machine with 3000 ATK / 2500 DEF; Present in 400 decks across 51 distinct archetypes; 100% inclusion in Machina, Crystron, Machines, and Earth Machine deck archetypes
- Observed: Appears in 5 recorded combos with 64.4 average power index; Acts as starter in 1 of 5 combos (20%); appears in end hand in 1 of 5 combos (20%); No recorded appearances as material, payoff, or end-board piece; 80% co-deck rate with Therion King Regulus; 72% co-deck rate with Superdreadnought Rail Cannon bosses; Runs at 1.13 copies per deck average; distribution: 1-copy (89.5%), 2-copy (8%), 3-copy (2.5%); Featured in CORE sections of Earth Machine and Train guides
- Inferred: Level 10 EARTH Machine type makes it optimal for Rank 10 Xyz summons based on high Superdreadnought co-deck rates; GY recursion provides resilience to board wipes and removal during extended games; Quick-effect classification allows removal during opponent turn, enabling reactive plays; Searchable via Machina support engine given 100% inclusion in dedicated Machina decks
- Data gaps: No banlist token supplied; assumed unlimited (3 copies legal in all formats) Combo evidence thin (only 5 recorded combos) and skewed toward Earth Machine, limiting visibility into other archetypes' combo generation Card does not appear as material or payoff in any recorded combo, suggesting combo database may be incomplete for boss monster roles No edge-case rulings documented, though none indicated as problematic
