tokens are eye candy :smile::smile::smile::smile::smile:
seriously though
they will be a currency with which you will be able to pay for your trades-see PTCGO's multiplayer screenshots thread.
The duration of your trade(how long your trade will be shown in the trade section) will be determined by how many tokens you will pay for,for a maximum of 24 hours if i remember correctly.
and before you ask when that will be available--->"soon", "coming soon" :lol:
