Megaroid City — Power Evaluation
Final Score: 53 ± 5 · Confidence: Medium
- Intrinsic: 54 · Deck: 53 · Meta: provisional
- Primary role: Searcher / Tutor · Secondary: Support, Resource generator
Why it scores here
Megaroid City excels as a Roid-specific searcher and resource manager, enabling consistent access to Roid support cards with minimal garnet risk. However, it provides no opponent-facing disruption and zero combo evidence suggests it is primarily a support utility piece rather than a board-builder. Its value is concentrated in dedicated Roid homes like Speedroid, where the tutor-into-searcher loop and Extra Deck Fusion compatibility create a clean, efficient package.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 72 | Plays as a field spell with minimal activation barriers; runnable at 2–3 copies in 104 decks across Roid and hybrid archetypes without brick risk. (observed) |
| Combo & Conversion | 28 | Zero recorded combo appearances and no board-building capability; functions as a support/tutoring tool, not a combo driver or extender. (verified) |
| Resource Economy | 58 | Destroys a card you control and tutors 1 from Deck, maintaining resources; GY send provides secondary utility without generating advantage. (inferred) |
| Effect & Interaction | 12 | Entirely self-supportive with no negation, removal, or opponent interaction; exists only to assist Roid monsters in combat and searches. (verified) |
| Material Utility | 8 | Field Spell type precludes use as material for Fusion/Synchro/Xyz; no body value even when effect is negated. (verified) |
| Resilience & Flexibility | 55 | Persists as a field spell and provides ongoing battle support, but fragile to field wipes; Extra Deck restriction is minor in Fusion-centric Roid homes. (inferred) |
| Deck-Building Efficiency | 77 | Fills a clean slot in Roid decks with standard 2–3 copies; minimal lock-in effects since Roid is already Fusion-focused and benefits from GY setup. (observed) |
Calculation
Weight profile: Primary role: Searcher/Tutor. Intrinsic ≈ 54, Deck ≈ 53, Meta = provisional. Modifiers: none. Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Tutor effect ensures minimal garnet risk in Roid decks
- Runs cleanly at 2–3 copies; establishes redundancy and consistency
- Enables Roid searcher loops alongside dedicated Roid support cards
- Battle effect (ATK/DEF swap) provides combat flexibility
- Appears across 14 archetypes, suggesting broader applicability than pure Roid
Weaknesses
- Zero combo evidence; no role as a board-builder or combo driver
- Provides no opponent-facing disruption or interaction
- Extra Deck restriction limits flexibility in non-Fusion strategies
- Field Spell type is fragile to removal (Twin Twisters, etc.)
- Tutoring is Roid-specific; limited generic utility outside Roid homes
- Battle effect is niche, requiring active combat to generate value
Counters / choke points
- Field Spell removal (Twin Twisters, Heavy Storm, Cosmic Cyclone)
- Cards that prevent spell activation (Shifter, Dimension Shifter in edge cases)
- Decks with no Roid cards cannot leverage the tutoring effect
Best use
Roid tutor and resource manager; field spell support. Decks: Speedroid, Pure Roid, Invoked Roids. Suggested copies: 3.
Evidence & gaps
- Verified: Card tutors roid cards from Deck to hand on activation (card text); Extra Deck restricted to Fusion Monsters when either effect is used (card text); HOPT on both effects (card text); Appears in 104 decks, primarily at 2–3 copies (deck data)
- Observed: Speedroid is primary home at 25% of deck sample (deck data); Commonly paired with Roid Fusion enablers (Power Bond, Ready Fusion) and Roid support (Submarineroid, Mixeroid) (deck data); Guide mentions as core Roid support card (guide data)
- Inferred: Searcher role enables Roid deck consistency when chained with other Roid tutors; Battle effect (ATK/DEF swap) provides combat flexibility in damage calculation; Extra Deck restriction is minimal cost in Fusion-centric homes like Speedroid; Cross-archetype appearances in Therions, Kashtira, Gandora suggest hybrid Roid inclusion or suboptimal play
- Data gaps: No combos supplied — cannot measure true combo conversion, role as board-builder, or appearance frequency in recorded lines No StatisticsCard usage data — archetype inclusion percentages beyond the 104-deck sample No explicit confirmation of cross-archetype appearances (Therion, Kashtira, Gandora, Gadgets) as hybrid Roid builds or alternative uses Limited guide context (3 guides in Vietnamese with minimal English detail)
