Check out this awesome fan made Sonic the Hedgehog card game!
There are 2 starters decks and 3 booster packs that will give you random cards with different rarities each time you click on a pack! There is also a rule book that comes and shows you how to play the game! You can actually print off the cards and play them anywhere you want like say at your friends or anywhere on the go!
I would choose the Hero Deck because I like the cards that comes with it!
