2019: Release of HS Battlegrounds. Firstly, it looked pretty boring... Until you got a chance to play ;)
2020: Finally getting whole classic set for free (or making it way easier to collect). Maybe this would encourage more new players to join.
My favourite moment was winning against big priest despite Barnes on turn four. With a small help of Emperor Thaurissan combo Brann Bronzebeard + Kazakus + Zola the Gorgon + Echo of Medivh turned out toto be pretty good! ;)
