When designing the four aforementioned cards, Blizzard were thinking about new players' first experiences playing Hearthstone. The new Classic cards were designed to be relatively straightforward while still creating some exciting moments, and give players a chance to see and play with cards that they don't own. At the same time, it's important that the new Classic cards aren't so powerful that they limit future design or cause problems since they're intended to permanently remain in Standard.[1]
