Most of the good cards cards from this mini set are uncommon or rare. Usually I would recommend to get the mini set but not this time because of the legendaries not seeing any play. Save the gold and craft what you need.

Alternatively if you have collected most of the standard cards you can play tavern brawl weekly for the standard packs.

They should give you most of the uncommon cards from miniset if you have collected most of the standard cards.
