Hi,
For new players the events have been changing on and off for some time , they either start after you have made 15 wins in adventure , then it was changed 3 days after you make you account, then it was changed back to 15 stars (wins) in adventure . Then the next event should start in 1 week after the last one ended , or sometimes even sooner. For the rest who have had all of the events so far , it is usually 1 event per month
As i see now on a brand new account starts after you made 15 battles in adventure , so idk why on yours states as coming soon ...very odd ,
