Saturday Night Clash is an event that begins at 08:00 Server time (GMT) on Saturday and ends at Midnight PST (08:00 Server Time on Sunday). Prior to January 15th, 2013, it started at 20:00 server time and ended at 08:00 server time the following day.
When it was first introduced on August 14th, 2012 during the weekly update, anyone who competed in a Draft would receive the award, regardless of how they placed in the draft or how many drafts they joined. However, the September 18th, 2012 update changed to a progressive system, offering rewards for participating in a variable number of drafts.
Unless otherwise noted, participants receive only ONE (1) copy of the reward, irrespective of how many drafts they complete.
