Mulligans
Hit legend for season 42 pretty decent agasnt the meta now with midrange game versus priests and rogue decks
Pro having a lot of taunt minions helps to midrange game with stone hill defender and end gaming with your Tirion 5/3 weapon.
Try hold the game and go with the flow until turn 7/8 and try to go for face and end game.
Lich king is an optional card it helps on ending game vs control deck.
