My favourite skin in all of overwatch including the events so far is the sombra summer games skin
I like the winter one as well but that summer games is mighty good
I was dying to get it once i saw it and for the entirety of the event i never got it so i lost hope that will ever get it until 2 days before the event was going to end
Late at night i got a lootbox and i got that skin
It was a glorious moment for me
