Hi I recently came across 8 packs of Evo-Crushers of Doom, Shobu's Fire Deck, and Kokujo's Darkness Deck in my storage. I am curious how I might be able to sell these cards at a reasonably fair value. My research tells me that I have some value here but the trading volume is thin so I would like to know what would make sense as a buyer and seller. Thanks!
