All Cards in the list are free to anyone when you start the game.
The aim of this deck is to control the early game with your Inferno Cannon and White Tiger minions and then play an aggro late game with Hercules, Fury and Brute. You will also have decent draw power because of your Elder Harpy.
On Turn 1, you should always be focused on playing a White Tiger, this is because if you keep it around long enough, it should be very tanky and can kill some squishy enemy minions.
When opening packs, you are likely to come across some extra cards.
You should experiment with the deck with your own cards.
