More info on YCS #100
More information about the 100th YCS has gone up on the official Yu-Gi-Oh! TCG site, including prize support etc.
You can find all the info you need by hitting this link (there's a lot there, so have a read). Below are the 2 special playmats that will be given out at the event. One of the cool things about the Tour Bus mat are the 3 "circles of light" surrounding the YCS logo. Those are in fact the names/locations of all 100 YCS events to take place so far, a nice touch.
