E-Card

The E-Card series spans Japan’s e-Card era of December 2001 to October 2002 and the English Expedition, Aquapolis and Skyridge sets. Its cards carry dot codes for the Game Boy Advance e-Reader, and Aquapolis and Skyridge added Crystal type Pokémon such as Lugia and Charizard. Skyridge, the last Wizards of the Coast set, is widely reported to have had a single print run, which helped push its prices up.
