Attempt to get and maintain a neutral or favorable board state going into turn 5, then go wide repeatedly to either finish the quest or to smack your opponent with a Sea Giant.
Nine Lives is the main reload tool and it fits the game plan very well, since you can hit Replicating Menace or Scarab Egg, which will generate 7 minions for 7 mana. Questing Explorer and Halazzi, the Lynx provide extra reload.
Leeroy Jenkins is cute since he sneakily counts for 3 minions, which can give you a huge burst if you play him, complete the quest, and hero power in the same turn.
Note to myself. This probably wants Knife Juggler. Most cuttable are likely Fireworks Tech and 1 Swarm.
