[5] The game was praised for the way it immersed children in the Harry Potter universe.

Other common keywords include designations representing each of the four Hogwarts houses: Gryffindor, Ravenclaw, Hufflepuff, and Slytherin.

These expansions include Quidditch Cup (November 2001), Diagon Alley (March 2002), and Adventures at Hogwarts (June 2002).

The fourth and final expansion released was Chamber of Secrets, which has 140 cards plus 55 Foil or Hologram Portrait Premium rares (October 2002).

[citation needed] After releasing the last expansion set in 2003, Wizards of the Coast discontinued making HPTCG cards.

"Foil premium" cards are partially "shiny", having thunderbolts and stars as theme for the "additional covering".

They are similar to foils, except that the picture of the character has a holographic quality that gives the impression of "popping out".

Theme decks, a special kind of starter pack, were released to the public with the Chamber of Secrets set.

The packaging for two additional theme decks (Hannah Abbott's Spellcaster and Dean Thomas' Restrike) was made for a toy fair in 2001, but the products were never produced.

[15] In 2002, Wizards of the Coast filed a lawsuit against former vice president of operations Charles Federline, alleging that he cost the company more than $93,000 by undermining the bidding process for the print work for the cards.
