The first time a monster(s) is Summoned to your opponent's side of the field each turn, inflict 800 damage to your opponent. During the Battle Phase of the turn this effect is activated, you can negate the attack of 1 monster your opponent controls. You can send 1 face-up "Trap Reactor・Y FI", 1 face-up "Spell Reactor・RE" and this face-up card you control to the Graveyard to Special Summon 1 "Flying Fortress SKY FIRE" from your hand, Deck, or Graveyard.
Summon Reactor SK — Power Evaluation
Final Score: 48 ± 8 · Confidence: Medium
- Intrinsic: 49 · Deck: 47.5 · Meta: provisional
- Primary role: Extender · Secondary: Board breaker, Recovery/Recursion
Why it scores here
Summon Reactor SK converts its on-field presence into a fixed 800 damage per opponent Summon and a one-attack negate in the Battle Phase, then pays three cards (itself, Trap Reactor Y FI, Spell Reactor RE) to Special Summon Flying Fortress SKY FIRE from hand, Deck or Graveyard. The recursion line is the main value, but it costs three cards for one body and the card has no combo evidence showing what that body does next, so the score stays in the middle band. The 2000 ATK and Level 5 body earn no points on their own; the score rests on the text-supported Extender line and the observed 16-deck usage.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 55 | Needs to be face-up on the field and relies on Cyber Dragon and Machina shells (8 and 5 of 16 decks), but no starter or searcher data exists to show how it is reached (observed deck presence, inferred route). |
| Combo & Conversion | 50 | The text lets it summon a Flying Fortress SKY FIRE from hand, Deck or Graveyard, but no recorded board confirms the resulting line (inferred from text). |
| Resource Economy | 35 | Three cards are sent to the Graveyard for one Special Summon, a poor cost ratio that is only partly recovered by the body coming back from the Deck or Graveyard (inferred from text). |
| Effect & Interaction | 45 | The Battle Phase negate hits one attacking monster per activation and the 800 damage is a steady ping, but both are situational and need the card on the field (verified from text). |
| Material Utility | 45 | A Level 5 DARK Machine is a usable material, but the card must be face-up and sent away for its own effect, which makes it awkward as material (inferred from text and stats). |
| Resilience & Flexibility | 35 | The whole effect lives on the field, so one removal or bounce ends the damage and negate, with no hand or Graveyard backup (inferred from text). |
| Deck-Building Efficiency | 40 | Three copies run in 15 of 16 decks with no garnet, but it needs two specific Reactor partners that co-occur in 93.8% of the sample (verified: deck stats). |
Calculation
Weight profile: 0.7 Extender + 0.3 Board breaker/Going-second. Intrinsic ≈ 49, Deck ≈ 47.5, Meta = provisional. Modifiers: Specific partner dependence (-3). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Deals 800 damage on each opponent Summon, a repeatable effect while it stays on the field
- Can negate one attacking monster in the Battle Phase
- Recursion line brings a Flying Fortress SKY FIRE back from hand, Deck or Graveyard
- Low-cost role within its own deck: 3 copies in 15 of 16 decks, no garnet
Weaknesses
- Requires three cards to be sent for one Special Summon, which is card-disadvantageous
- Depends on two named Reactor partners
- Effects need the card face-up on the field, so one removal or bounce ends the line
- No combo evidence showing a finished board
Counters / choke points
- Generic on-field removal or bounce, since the effects need the card face-up (inferred from text)
Best use
Extender / summon-punisher with a Battle Phase negate. Decks: Cyber Dragon, Machina. Suggested copies: 3.
Evidence & gaps
- Verified: Card text: 800 damage on opponent Summon, Battle Phase attack negate, send three cards to Graveyard to Special Summon Flying Fortress SKY FIRE; Ran in 16 of 16 decks, 3 copies in 15 of them, average 2.88 copies; Co-occurs in 93.8% of decks with Trap Reactor Y FI and Spell Reactor RE
- Observed: Archetype split: Cyber Dragon 8 decks, Machina 5, Cyberdark 2, RaidRaptor 1; Formats listed: TCG, OCG, MasterDuel, DuelLinks
- Inferred: Primary role Extender, with Board breaker as secondary; Summon route is not tabled; accessibility rests on archetype shells; Effects are weak against removal because they need the card face-up
- Data gaps: no combos supplied: combo conversion is text-only inference no guides supplied no banlist token: assumed 3 copies (unlimited) no usage statistics (StatisticsCard): archetype inclusion is inferred from the deck sample only Flying Fortress SKY FIRE stats and text are not in the evidence pack
