Strategy & play
How Castform plays — derived from its stats and the rules of the game, not an opinion.
- Not a main attacker — its job is search / tutoring. Run it as a consistency hub and protect it, because opponents will target the engine.
- Inflicts Sleep — they flip each turn to wake, so it’s a coin-flip lock: disruptive but unreliable on its own.
- Attacks on any Energy (Colorless cost) — splashable into any deck regardless of type.
- Colorless type, weak to Fighting ×2 — a Fighting attacker doing ≥35 effectively one-shots it.
- A single-prize attacker — prize-trade-positive against ex / V decks that give up two at a time.
How to beat Castform
- Exploit its Fighting weakness — ≥35 damage one-shots it.
- KO it to choke their draw / search engine.
- On the receiving end of a condition? Retreat, switch, or evolve to wipe it — conditions only stick to the Active.

Frequently asked
How can I tell if my Castform is real?
Castform 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.
