Sunny Castform

Sunny Castform is a rare card from the Delta Species set, part of the EX series that featured Pokémon with altered types due to scientific experimentation. While Delta Species cards have nostalgic appeal among collectors who appreciate the unique alternate-type mechanic, Castform variants generally maintain lower popularity compared to more iconic Pokémon. The complete absence of pricing data indicates this card has seen minimal market activity and likely trades infrequently.
