you can get a starter pack at the firehouse
this pack will include a map and a key/keyhole card.
That key is your "identifier" for the game. Meaning you'll need to use it to resume your adventure.
For example, if you visit MK twice during your stay, you'll need your keyhole card to resume the game where you left off. If you forget that key, you can get a new one at the firehouse, but you'll start a new game and lose any level you've gained during your first play.
Getting new cards can be done in several ways.
You can get one pack of cards per day (and per playing guest) at the firehouse. But some CMs will only give those packs if you've actually played the game. (used at least one game window inside the park)
some CMs will give the packs anyway.
(in that regard, some CMs will require that a guest be old enough to play to register that guest on the game. For example our son who was 5 then was not registered as a player, and did not receive cards)
You can also get a pack of card on the same day if you have levelled up.
you can also buy a booster pack from the Emporium (or
disneystore) this will be a board game to play at home, but will include 7 cards that can also be used in the park for the interactive game. (pricey, at $14)
There are exclusive and rare cards distributed during
MNSSHP and
MVMCP
CMs at the firehouse can walk you through a sample game to learn the basic rules.
You can get one pack per Magic Band (or ticket) per day. I can't remember off hand how many cards in a pack - about a dozen I think.
IIRC it's 5 cards per pack.
we were buying party cards online and also swapping party cards
