Coveted Arms Cache

Promo Edition
A promotional edition of this set was given out to players who purchased an Economy Card from the shop venue at The International 2014. These editions came in quality, and included an Autograph Rune of its creator. Promotional bundles have the word "Promo" in their names. Cards purchased from the Secret Shop contain only the Ziedrich autograph rune.

Gems
Special card sets given by Valve directly to the artists contain two autograph runes: Jeremy Klein and Ziedrich.
