Why it scores here

Sunseed Shadow scores on its role as an Extra Deck extender for Sunavalon and Sunvine: it can be Special Summoned from hand only while you control a Plant Normal Monster, and from the GY it banishes itself to bring a same-named monster out of the Extra Deck as a negated copy. Its 0 ATK and 400 DEF earn nothing, and the card's effects give it no opponent interaction. The strongest signal is deck-level: it sits in 165 of 165 sampled decks with 100% overlap with Sunseed Genius Loci, Sunvine Sowing and Sunavalon Dryas, which supports a real, practical home but is not proof of intrinsic strength.

Axis scores

Axis Score Evidence
Accessibility 55 Hand summon needs a Plant Normal Monster, and the GY route needs it to be in the GY first; it runs in 165/165 decks at 1.19 average copies, so access is live but conditional (observed).
Combo & Conversion 50 Its GY effect turns a Link-2 or lower Sunavalon/Sunvine into a negated same-name Extra Deck body, a fair board step with help rather than a one-card board; no combo boards were supplied (inferred from text).
Resource Economy 45 No card advantage: the hand summon is free and the GY route costs the card itself, with no search or draw (verified from text).
Effect & Interaction 15 No negation, removal or hand-trap effect against the opponent; the negation applies only to the copy it summons (verified from text).
Material Utility 35 Level 1 Earth Plant non-Tuner is a modest generic material, and the GY effect banishes it from the GY, which limits its value as material (inferred).
Resilience & Flexibility 40 Both effects are once per turn and gated by the Plant Normal condition and a Link monster on board, so one interruption can shut the line down (inferred from text).
Deck-Building Efficiency 55 Runs at one copy in most decks with no garnet or lock, but the Sunavalon/Sunvine shell is needed to make it worthwhile (observed from deck data).

Calculation

Weight profile: 0.7 Extender + 0.3 Starter. Intrinsic ≈ 47.5, Deck ≈ 50.75, Meta = provisional. Modifiers: Self-restriction on Special Summon (-2). Final formula: 0.40*Intrinsic + 0.60*Deck

Strengths

  • Hand summon is free and needs only a Plant Normal Monster to be on the field.
  • GY effect brings a same-name monster out of the Extra Deck as a negated copy, extending the Sunavalon/Sunvine line.
  • Appears in 165/165 sampled decks with 100% overlap with Sunseed Genius Loci, Sunvine Sowing and Sunavalon Dryas.

Weaknesses

  • Hand summon requires a Plant Normal Monster you control.
  • GY effect banishes the card itself, so it is a one-shot cost, not repeatable value.
  • The copy it summons is negated and the rest of the turn is restricted to Plant Special Summons.
  • Target is limited to a Link-2 or lower Sunavalon/Sunvine monster you control.

Best use

Hand-started extender that puts a Link-2 or lower Sunavalon/Sunvine body into the Extra Deck line. Decks: Sunavalon (archetype 1727), Sunavalon (archetype 867). Suggested copies: 1.

Evidence & gaps

  • Verified: Card text: hand summon needs a Plant Normal Monster; GY banish targets a Link-2 or lower Sunavalon/Sunvine; the summoned copy is negated; each effect is once per turn.; 165 of 165 sampled decks run it, average 1.19 copies, 100% overlap with Sunseed Genius Loci, Sunvine Sowing and Sunavalon Dryas.
  • Observed: Sunavalon archetype 1727 is in 60.6% of decks; gameplay type 3 is 62.4% of decks.; Most copies are 1 (139 of 165 decks).
  • Inferred: Extender is the primary role because the GY effect is the Extra Deck summon.; Combo conversion is text-only with no combo boards supplied.
  • Data gaps: No combos supplied, so combo conversion and starter/material shares are text-only inference. No banlist token; assumed 3 copies. No usage statistics (StatisticsCard); inclusion is inferred from the 165-deck sample only. No counter evidence supplied. Card's own archetype field says Sunseed, but deck evidence is almost entirely Sunavalon/Sunvine; archetype membership not verified.
