So the goal of the pruning was to drop cards that went face? To make the game more minion-focused then - and maybe games less super quick with aggro?
But cards like Blizzard went away too - lot of freeze cards so I guess they don't want that anymore?
It seems like the goal is to get rid of non interactive design space. It isn't fun to play when your opponent stops you from doing anything or wins without interacting with you.
