From esreality thread:
After a long hiatus the Promode community has revived the classic Challenges duel series. Initially spawned as a platform to place the best duelers in the Promode community against one one another, the latest edition of the cup will look to provide a similar level of excellence as displayed in the very early 2000s.
Challenges-EU 2016 is a European open duel cup, that will be played on 12:00 EDT, 8 October 2016. This will be a single-elimination tournament, with all matches consisting of one best-of-three (BO3) game. The Grand Finals will be played as a best-of-five. To play please sign-up via Challonge, and join the Challenges-EU 2016 Discord server.
More complete information can be found in the esreality thread such as admins, map pool, prize pool, general rules, and server information. Note that while this is a primarily European tournament North Americans are allowed to play provided that they are willing to play on European servers. If you have any questions about the event or CPMA in general feel free to ask.
