I find it alot easier and quicker and faster on the site, and experiment with a few clans, pick either a full deck or a mono(half) deck. The full deck contains 1 clan and mono contains 2 clans. Then you can get decks which have a 'splash' which is 7 characters of 1 clan and use 1 card of a separate clan.
First pick wich you wont a mono for half deck.
mono: 8 cards from one clan this deck can have a leader an be easly to still handle.
half: 4 cards from 2 diffrent clans ghiest / piranas haven a leader in this type of deck is harder to handle.
then also start usen the collection pro its the best.
make use you know the clan test out a few an see wich bounes you like the best.
