If you want to play competitively then you should have the majority of good staple cards, which are extemely hard to come by (talking about Leeroy, Faceless Manipulator etc), then you should buy a lot of packs with real money and pray for the best. If you don't have any money to throw away, you can always try some F2P decks from the internet, which require a couple of expert blues and whites.

Then there is the problem of competitive play in a casual-oriented game. The game is 75% luck and 25% copying other people's decks from the internet. You can't climb the ladder faster even if you're truly good and using your own "super awesome unique deck", because the game is a cleverly designed grinding system that won't let you get legend until you have won a certain number of matches.

It's still a fun game if you're trying it out for the first time and you aren't aiming for competitive play.
