Long before Hearthstone was announced in March of 2013, the development team had been making cards to go into the game. In the six-plus years since, thousands upon thousands of cards have been theorycrafted, designed, coded, tested, implemented, played and enjoyed. Cards with a more basic "pack filler" design may take only a few man-hours to create, design and test before they go live. And others, the development cycle can be much longer. In the most recent Hearthstone card expansion Saviors of Uldum the development team pushed their creative limits to new heights by creating a card that took more man-hours than any other in the game's history, Zephrys the Great. A unique design that combines skill and luck, this genie means business and has captured players interest since the expansion went live in recent weeks.
