Goblins vs Gnomes is being retired! Once the Standard format is released with the launch of the first card expansion in 2016, GvG cards will no longer be available in the Store and will only be playable in the Wild format. Cards will still be obtainable using Arcane Dust.
You should consider updating this now that Wild Packs can be purchased in the Blizzard store.
