Dear Blizzard,

Learn the lesson MTG did a decade ago: free-playing cards is inherently almost impossible to balance. The card is either too weak to have a real impact or absolutely busted and meta-distorting (e.g. Patches, Corridor Creeper, Naga Sea Witch + Giants, etc). If it's the former, nobody plays it, and, if it's the latter, nobody wants to play against anybody playing it.
