All in card «Whizbang the Wonderful»*
*This card has entered free mode, in standard mode it will not be playable.
STRONGLY recommend to everyone who doesn’t have a playful deck to create a card «Whizbang the Wonderful». In the video I clearly show how to create it. This card contains to date 18 actual decks, of which you probably do not have a card. This card costs 1,600 dust. To get enough dust, you’ll have to spray out unnecessary cards that you have.
When Whizbang is added to a player’s deck in the collection manager, he replaces the hero for that deck in the deck screen, removes all other cards from the deck, and renames it to «Whizbang is Wonderful». When the player starts a game, their deck will be one of the 18 current non-classic Deck Recipes, chosen at random, using the class’s standard hero (not necessarily your favorite hero for that class). You will not be shown which of the class’s decks you have.
