Dominion Summer Icon Clarification, someone please reply.

So I just got the warning that dominion's retiring, and people with 100 wins get an icon. Ofc I've played hide and seek customs since the beginning of time but those dont count I have 76 wins, and i'm grinding for 100 before it closes to get the icon. Do I have to have the 100 wins now? Is it still possible for me to get? Or am I just wasting my time over a lost cause. Cause i'm grinding dominion wins atm and if they already gave them out then i'll just move on with my life
