Lapras

Lapras is just 18 days old and still in the steep part of the typical three-month post-release price decline, so patience might pay off if you're not in a rush. At £7.33, this card is worth monitoring over the coming weeks rather than buying on impulse, especially when newer Pokémon releases tend to soften considerably before stabilising.

• CautionSet is 2 weeks old. Prices typically fall for the first three months after release.
