You can easily buy a decent deck for the money you got, you got Lucky
on pulling kallindra, really nice way to start out as she
imediatly give you some amount of cash to work with!
try some of the atk manipulation clans, they are beginner friendly. As you play more you will figure out how to build
your decks better and your ability to predict your opponent will go up.
Try a 4/4 split mabey, you can get the 4 strongest cards from one clan, and the 4 strongest from another.
giving you either stronger characters or 8 strong characters for a cheaper price a lot of the time. Ofcourse as a disadvantage
you won't always have your bonus on all your characters.
