NeoDeck

The NeoDeck was the original online trading card game on Neopets. Players can collect their trading cards and place them in their NeoDeck, which can be shared and veiwed by others through a link in their User Lookup.

Originally, the cards had stats placed within them, to be used as part of a game within Neopets, but was taken down, and replaced with the concept of just card collacting.
