So far there are four expansion sets. The first is Quidditch. This has a new lesson and type of card in it. First is the lesson card, which is the Quidditch Lesson. The snitch represents it and its color is yellow. This brings in a whole new variety of cards. A few new character cards come into play such as several Quidditch players and professors. Among them are the Match cards. The rules for Match cards are as follows: 1.) To play a Match card, you need the required amount of Power and you use up only 1 of your Actions to put it into to play. 2.) There can only be one Match in play at a time. Meaning if you have a Match in play, neither of you can play another one till the first one is won. 3.) Both players (or all if there is more than 2 players in the game) can win the Match. Winning a Match is not limited to the person who played the Match card. 4.) Where it says, “To Win”, is what a player needs to do to win the Match. Unlike Adventure, it doesn’t have to be done all at once. For example on Practice Match it says you have to do 5 damage to your opponent to win. A player can do 2 on one turn and 2 on another and then 1. You just have to keep track of the damage being done (the pop-out counter chips that come in the pre-built decks are useful for these times). 5.) Where it says, “Prize”, it is what the winner gets. Once a Match card is won it goes into it’s owner’s discard pile. A helpful hint to playing Match cards is to make sure you have plenty of direct hit cards. Such cards are Fouled!, Ouch!, Out of Control (which only drawback is that you need 10 lessons in play to play it), and Power Play among many others. To know more about these cards visit the Quidditch spoiler. Another part of this set is that the Uniqueness rule does apply to two different unique cards that represent the same character. For example, if Harry the Seeker is in play, nobody can play Harry Potter or Harry the Seeker.
The next expansion set is the Diagon Alley set. This set is more advanced than Quidditch and the Base set. New additions arrive for the previous sets cards including a new Match card, Gryffindor Match, where the first player to do 12 damage gets two more Actions on their turn. Lee Jordan and Griphook make an appearance in this set as well. Packing some hard-hitting creatures like Hebridean Black Dragon and River Troll among others, your deck will have more of an edge to it than it did before. To check those cards out check out the Diagon Alley spoiler. As well, the uniqueness rule in the Quidditch set applies to this set.
In the Hogwarts set; new characters come to life as well as other new additions to other types of cards. You can be Albus Dumbledore with ability: If you have at least 4 Lessons in play, your Spell cards with a printed Power cost of 6 or more need 2 less Power to play. (You still need at least 1 Power that matches.) Making it easier for you to pull out bigger and better cards than you normally would. Another special card is the Philosopher’s Stone card. It’s ability as follows: You may use 2 Actions and discard this card from play to put all Lesson cards in your discard pile into play. Then shuffle all non-Healing cards from your discard pile into your deck. When you build your deck, you can put only 1 Philosopher’s Stone in it. Even though being able to have only one of it in your deck is a drag, it’s abilities makes up for it.
The newest expansion set is the Chamber of Secrets set. New set of spell cards called password, where your opponent guesses the card you have in your. Guessing right protects them, guessing wrong inflects them with a hefty amount of damage. Then a new location taking you to Greenhouse Three, where Harry, Ron and Hermione study and take care of fascinating and unusual plants. Also more of the Weasley family is seen, such as the youngest one, Ginny, and their mom, Molly. This set has just been released so look out for it!
