RE: Contest – Choose your theme and win 500 DEC! #3

A post for new players on how can one trade cards smartly to grow their account. Like which cards to bug and in what order. It took me 2 years or so to build a deck for champion league. I'm sure it would be much easier and faster if I were guided well.
Even if I'm a 2 year old player I don't own a lord A. That's the biggest regret I have.
