Strategy & play

How Silcoon plays — derived from its stats and the rules of the game, not an opinion.

  • Not a main attacker — its job is Ability-based draw/search. Run it as a consistency hub and protect it, because opponents will target the engine.
  • Needs Grass Energy to attack — your line must supply that color.
  • Grass type, weak to Fire ×2 — a Fire attacker doing ≥45 effectively one-shots it.
  • A single-prize attacker — prize-trade-positive against ex / V decks that give up two at a time.
  • Retreat cost 3 — gets stranded Active if gusted; run Switch / Escape Rope or a Float Stone-style Tool.
  • A Stage 1 — one step up from Wurmple; doesn’t help your opening hand, but quick to set up.

How to beat Silcoon

  • Exploit its Fire weakness — ≥45 damage one-shots it.
  • KO it to choke their draw / search engine.
  • Gust it before the evolution is set up.
  • Trap it Active — 3 retreat means it can’t escape without help.

Frequently asked

How can I tell if my Silcoon is real?

Silcoon is not on our list of commonly-counterfeited cards, but counterfeits exist across every set. Check the back-light test (real cards have a black inner layer that blocks light; counterfeits glow through), the rosette dot pattern on the back under magnification, font weight and kerning on the card name, and the holofoil pattern if applicable. For high-value copies we recommend submitting to a professional grader (PSA, BGS, CGC) for tamper-evident authentication.

What is Silcoon worth?
