Cyber Dragon Sieger — Power Evaluation

Final Score: 51 ± 6 · Confidence: Medium

  • Intrinsic: 48.7 · Deck: 56.4 · Meta: provisional
  • Primary role: Boss/End-board · Secondary: Material body

Why it scores here

Cyber Dragon Sieger is a 2-rating Link body with 2100 ATK. Its one effect gives a Machine monster 2100 ATK and blocks battle damage from that monster's attacks during the Battle Phase, so its value lies in the end-board and battle-phase pressure it adds to the Cyber Dragon engine. It is in all 400 sampled decks, and it appears in all 13 recorded boards, but it is a starter or searched piece in none of them and is a payoff or end-board piece in 3. High ATK and the 100% deck inclusion did not earn points by themselves; the score comes from the consistent end-board role and the cheap, single-copy deckbuilding cost.

Axis scores

Axis Score Evidence
Accessibility 55 The card is in 400/400 sampled decks at 1.03 copies on average, but its combo appearances show no starter or searched role, so access depends on the Link summon from the Cyber Dragon engine (observed; inferred for the Link route).
Combo & Conversion 65 It appears in 13/13 recorded boards with an average power index of 80.5 when present, and as a payoff in 3 of them (observed); the boards are driven by partner pieces, not by this card alone.
Resource Economy 30 Its text contains no draw, search, or refuel, and no recorded board attributes card advantage to this card (verified from text; inferred for the combos).
Effect & Interaction 15 The effect is a battle-phase pump with a no-damage clause and provides no negation, removal, or hand-trap reach (verified from text).
Material Utility 40 It is never recorded as material (material role 0%), and as a Link-2 it is a weak material; its name becomes Cyber Dragon in the GY, which a guide cites for Chimeratech Fusion (observed for the 0%; inferred for the GY name route).
Resilience & Flexibility 45 Its effect is once per turn and needs a Machine target with 2100+ ATK, and the card is a single body with no recursion, so one negate ends it (verified from text; inferred from the once-per-turn wording).
Deck-Building Efficiency 70 It runs at 1 copy in 389 of 400 decks with no garnet or lock, and the Machine requirement is met by the engine it already runs in (observed).

Calculation

Weight profile: Primary role Boss/End-board, no secondary blend (Material body secondary noted but not blended; the combo evidence puts it on the Boss/End-board side). Intrinsic ≈ 48.7, Deck ≈ 56.4, Meta = provisional. Modifiers: Machine-dependent summon restriction (-2). Final formula: 0.40*Intrinsic + 0.60*Deck, then -2 modifier applied to Final

Strengths

  • Present in all 400 sampled decks and in all 13 recorded boards
  • Cheap and clean to run at a single copy, with no garnet or lock
  • Adds 2100 ATK end-board pressure and blocks battle damage from that monster during the Battle Phase
  • Name becomes Cyber Dragon in the GY, which supports Cyber Dragon material routes

Weaknesses

  • No starter, searcher, or draw role in any recorded board
  • No negation, removal, or hand-trap reach
  • Needs Machine materials on the field, so it is dead without the engine
  • Weak as Link material (Link-2) and never recorded as material

Counters / choke points

  • Negating the effect or removing the Machine monsters it needs (inferred from the effect's dependence on a Machine target)
  • Battle-phase interaction against the monster it targets (inferred from the once-per-turn effect)

Best use

Link-2 end-board and battle-phase pump. Decks: Cyber Dragon (archetype 716, 161, 545), Cyberdark (archetype 672). Suggested copies: 1.

Evidence & gaps

  • Verified: Link-2, LIGHT Machine, ATK 2100, arrows Left and Bottom; Effect: Battle Phase pump of 2100 ATK/DEF with no battle damage, once per turn, Quick Effect; Name becomes Cyber Dragon on the field or in the GY

  • Inferred: Access depends on the Link summon from the Cyber Dragon engine; Counters are limited to negating its effect or removing its Machine materials
