Hey Hearthstonians!
You can receive a free deck if you’re an existing player however it will require you to head on over to another server.
Eg:// If you’re currently playing on europe, just switch on america or asia in the battle.net region/account menu.
Complete the usual starting out quests and the tutorial then upon completion go into the settings menu and select the miscellaneous tab, then click skip to rank 25.
After that log out and then back in and then select a class from the pop up window for the free deck of your choice.
Your welcome.
