Mulligan for Alleycat, Crackling Razormaw, Candleshot, Corridor Creeper, Southsea Deckhand, Kindly Grandmother and also Golakka against aggro. Against Warlock I also tend to keep Spellbreaker and with Aggro Druid and Paladin it's nice to keep Rexxar even though it may slow your start. I've won lots of games by having it in hand by turn 6 when you really need to clear the board.
I wanted to play around with Hunter and Spiteful summoner so I
experimented and ended up with this deck. With minor alterations I
managed to climb from rank 15-5 in only one day and still climbing.
I’ve had lots of fun with it!
