Reactor Slime — Power Evaluation
Final Score: 60 ± 5 · Confidence: Medium
- Intrinsic: 60 · Deck: 63 · Meta: provisional
- Primary role: Combo enabler · Secondary: Starter, Searcher/Tutor, Material body
Why it scores here
Reactor Slime is a specialized combo enabler for Egyptian God decks, primarily valued for tutoring Metal Reflect Slime and generating token material for the archetype's Divine-Beast summon lines. The card's 500/500 stats and Level 4 body are not power drivers; instead, its utility comes from enabling the archetype's specific engine through tutoring and token generation. However, the main effect's severe summon lock—preventing non-Divine-Beast summons for the rest of the turn—significantly constrains flexibility and deck-building options, offsetting the tutoring value and limiting its applicability.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 65 | Runs at 2.46 copies per deck with 65% of decks running 3 copies, making it consistently available; however, it relies on hand draw as a Level 4 Effect Monster with no built-in search. (Observed) |
| Combo & Conversion | 62 | Generates 2 Level 1 Aqua tokens and tutors Metal Reflect Slime during the Battle Phase, but the main effect's Divine-Beast-only summon lock severely constrains the turn's plays; no combo boards supplied to verify practical lines. (Inferred) |
| Resource Economy | 60 | Token generation provides roughly +1 card advantage (1 card into 2 bodies), while the tutor effect is card-neutral; neither draws nor refuels, limiting resource gains beyond token generation. (Inferred) |
| Effect & Interaction | 20 | Card provides no negation, removal, or disruption on its own; relies entirely on Metal Reflect Slime and partner cards for interaction support. (Verified) |
| Material Utility | 68 | Level 4 body with low stats (500/500) is clean generic material for Synchro, Xyz, and Link summons; generates Level 1 tokens useful as Tuner fuel or tribute fodder, especially in Divine-Beast-heavy decks. (Verified) |
| Resilience & Flexibility | 55 | Offers dual-phase effects (Main Phase token engine, Battle Phase tutor) for some flexibility, but the main effect's summon lock greatly reduces in-turn flexibility and the card has no built-in protection. (Inferred) |
| Deck-Building Efficiency | 58 | Essential to Egyptian God (3 copies in 65% of decks), but the summon lock imposes a hard deckbuilding constraint to Divine-Beast synergy, limiting splashability and making it unsuitable for decks not built around that theme. (Observed) |
Calculation
Weight profile: Combo enabler (primary role). Intrinsic ≈ 60, Deck ≈ 63, Meta = provisional. Modifiers: Summon lock constraint (-3); High core redundancy (1). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Efficient tutoring of Metal Reflect Slime (91.9% co-deck rate confirms tight synergy)
- Generates additional material (2 Level 1 tokens) for Divine-Beast combo lines
- Dual-effect design provides token generation and tutoring in separate phases (Main and Battle)
- Level 4 body is generic material for Synchro, Xyz, and Link summons
- Consistent inclusion in Egyptian God (39.9% of deck sample, 3 copies standard)
Weaknesses
- Summon lock to Divine-Beast-only restricts deck-building and limits flexibility during the turn of use
- Low base stats (500/500) provide no combat value and minimal impact if effect is negated
- No effect interaction; card provides zero negation, removal, or board disruption on its own
- Relies on hand draw for accessibility (no built-in search or tutoring into hand)
- No card advantage, draw, or refuel mechanisms beyond token generation
Counters / choke points
- Negation of either effect prevents tutoring and token generation
- Removal of the card before activating either effect
- Cards restricting Divine-Beast summons (e.g., aggressive combo interruption affecting the lock's intended targets)
Best use
Combo enabler and Metal Reflect Slime tutoring engine. Decks: Egyptian God, Divine-Beast support.
Evidence & gaps
- Verified: Runs in 371 decks at 2.46 copies average, mostly 3 copies (243 decks, 65%); Primary home is Egyptian God archetype (148 decks, 39.9%); Highest co-deck partner is Metal Reflect Slime (341 decks, 91.9%); Card text provides two once-per-turn effects: token generation with Divine-Beast-only summon lock, and Battle Phase tutoring
- Observed: 66 distinct archetypes run this card, though heavily concentrated in Egyptian God; High copy inclusion rate confirms core status in home archetype; Top partners align with Egyptian God archetype (Ra variants, Slifer, Soul Crossing, Ancient Chant); Gameplay type distribution shows control-heavy usage (56.6% control, 25.9% combo)
- Inferred: Combo enabler role inferred from dual effects (tutoring + token generation) and tight Metal Reflect Slime synergy (91.9% co-inclusion); Summon lock imposes deckbuilding constraint that limits flexibility and splashability outside Divine-Beast-focused builds; Material utility confirmed as Level 4 body with low stats, perfect for tribute and link material; Combo conversion measured from card text alone due to absence of combo boards; practical lines unknown; Resource economy is slightly positive via token generation (+1 net card) but tutor effect is neutral
- Data gaps: No combos supplied (0 boards) — combo conversion is inferred from card text only, with no observed practical combo lines to verify No guides supplied — no human strategy context or archetype-specific guidance available No usage statistics (StatisticsCard) — archetype inclusion percentages inferred from deck sample only No banlist token — assumed unlimited (3 copies legal in all formats) Metal Reflect Slime card text not supplied — cannot verify what interaction or disruption it provides
