tried mill druid, ran into a malchezzar deck with 60 cards.. just conceded right away.
Swapped to shaman for a quest. Went with tinyfin, tidehunter and everyfin and it's great against mill druid heh. I held back turn 1 to not reveal what I was doing, he goes off with innervates, 2 coldlights and then naturalizes both, milling me for like 2-3 cards. I drop 4 tinyfins and tidehunter next turn, he refills my hand and mills me for 2 again next turn, but I fill the rest of board with tinyfins and cast 4x everyfins for free. Had four 9/9s able to swing on turn 3.
