I am the creator of Heroes of Karth:Deathmatch. After researching various print-on-demand game sites I quickly came to the conclusion TGC was my best option. My best surprise was to find an extremely built game editor to work from. I am also very pleased to see improvements on shipping and the API code to enable me to sell directly from my website!
With my proofs received I feel my card quality is equal to Magic the Gathering!
Also like that there are contests: I plan to enter the dungeon one as my RPG Mines of Taas Dungeon Pack fits the criyeria very well!
I am impressed so far and highly recommend TGC!!
