During the End Phase of your turn, if you did not attack, you can make your opponent send cards equal to the number of face-up "Iron Chain" monsters you control from the top of their Deck to the Graveyard.
Poison Chain — Power Evaluation
Final Score: 26 ± 7 · Confidence: Medium
- Intrinsic: 29 · Deck: 32 · Meta: provisional
- Primary role: Utility · Secondary: Floodgate/Control
Why it scores here
Poison Chain scores in the low range because its recurring mill effect is gated behind two simultaneous conditions — controlling face-up Iron Chain monsters and forgoing attacks that turn — locking it into dedicated stall-mill builds. Within those narrow homes (primarily Naturia and Runick hybrids using the Iron Chain package), it contributes a repeatable end-phase win condition rather than immediate tempo or disruption. It cannot interact with the opponent during their turn at all, and one spell-removal response ends the entire engine. The card earns no credit from ATK or DEF; its score is driven by its niche but real strategic role confirmed by 9 decks averaging 2.78 copies each.
Axis scores
| Axis | Score | Evidence |
|---|---|---|
| Accessibility | 35 | Run as 3-of in 8 of 9 recorded decks requiring Iron Chain monsters already on field plus a raw draw; no confirmed spell searcher cited in evidence. (inferred) |
| Combo & Conversion | 20 | Zero combo appearances recorded; the card provides slow accumulative end-phase mill rather than board extension or immediate board presence. (verified) |
| Resource Economy | 30 | Persistent Continuous Spell mills opponent each end phase at no recurring cost once placed, but generates zero hand advantage for the controller. (inferred) |
| Effect & Interaction | 15 | Effect activates only during your own End Phase after forgoing attacks, providing zero disruption to opponent's actions at any other point in the turn. (verified) |
| Material Utility | 5 | Continuous Spell has no monster body and cannot serve as Synchro, Xyz, Link, or Fusion material under any circumstance. (verified) |
| Resilience & Flexibility | 25 | A single Spell destruction ends the entire mill engine, and both conditions — Iron Chain board and no-attack — must hold simultaneously every turn to generate value. (inferred) |
| Deck-Building Efficiency | 25 | Requires a dedicated Iron Chain monster engine and a passive non-attacking stall strategy; archetype-locked and only functional in specific hybrid builds. (inferred) |
Calculation
Weight profile: Utility (primary, 1.0). Intrinsic ≈ 29, Deck ≈ 32, Meta = provisional. Modifiers: No-attack condition (-3); Iron Chain archetype lock (-2). Final formula: 0.40*Intrinsic + 0.60*Deck
Strengths
- Provides a recurring end-phase mill engine with zero ongoing resource cost once placed on field
- Mill count scales directly with the number of face-up Iron Chain monsters controlled
- Synergizes naturally with control/stall archetypes (Naturia, Runick) that already avoid attacking
- Effective mill-to-deck-out win condition in reduced deck-size formats like DuelLinks (20-card decks)
Weaknesses
- Zero disruption during the opponent's turn — cannot respond to threats or interrupt plays
- Requires multiple face-up Iron Chain monsters to be meaningful, adding significant deck-building overhead
- A single Spell removal (MST, Twin Twisters, etc.) permanently ends the mill engine
- The no-attack condition is a serious ongoing tempo sacrifice in most game states
- Slow win condition that gives the opponent multiple turns to search answers or set up counters
Counters / choke points
- Mystical Space Typhoon, Twin Twisters, or any Spell/Trap removal immediately ends the mill engine
- Mass monster removal (Torrential Tribute, Dark Hole) clears the Iron Chain board and stops all milling
- Cards that benefit from or recycle the GY (Skull Servant, Necroworld Banshee) convert milled cards into opponent advantage
- Banishing effects (Macro Cosmos, Dimensional Fissure) prevent mill from being a viable win condition
Best use
Mill win condition in stall-oriented Iron Chain hybrid builds that naturally avoid attacking. Decks: Iron Chain, Naturia + Iron Chain (DuelLinks), Runick + Iron Chain (MasterDuel). Suggested copies: 3.
Evidence & gaps
- Verified: Continuous Spell Card belonging to the Iron Chain archetype; Effect requires face-up Iron Chain monsters on field and no attack declared that turn; Mill count scales with number of Iron Chain monsters controlled at End Phase; Nine decks in evidence run it in the main deck, averaging 2.78 copies; Appears in Naturia, Runick (Mysterune), and ZEXAL-themed builds; Zero combo appearances in any recorded board
- Observed: Run as 3-of in 8 of 9 recorded decks, indicating it is a core piece rather than a 1-of tech in those strategies; Consistently paired with the full Iron Chain monster suite (Blaster, Coil, Repairman, Snake) in 88.9% of decks; Dominant gameplay type is ID 7 (88.9% of decks), consistent with a single format home (inferred DuelLinks based on Naturia partner cards)
- Inferred: Naturia and Runick archetypes provide a natural no-attack framework enabling the condition without significant tempo loss; In a 20-card DuelLinks deck, 3-4 end-phase mills per turn can deck-out an opponent within 5-7 turns with a full Iron Chain board; No confirmed search route for Poison Chain itself; the deck relies on drawing it naturally across 3 copies
- Data gaps: No combos supplied — combo conversion is text-only inference No guides supplied — role confirmation relies entirely on the 9-deck sample No banlist token — assumed 3 copies (unlimited) across all formats No usage statistics (StatisticsCard) — archetype inclusion percentages inferred from small 9-deck sample only Gameplay type IDs not explicitly labeled — DuelLinks vs MasterDuel distinction is inferred from partner card identities, not from metadata
